Guide to Bi~olar Logic
Device Families

Since the introduction of the first saturating logic bipolar integrated circuit family (DM54/DM74), there have been many
developments in the process and manufacturing technologies as well as circuit design techniques which have produced new generations (families) of bipolar logic devices.
Each generation had advantages and disadvantages over
the previous generations. Today National provides seven
bipolar logic families.

is sacrificed. The propagation delays are increased threefold. These devices have a typical power dissipation of 1
mW per gate and typical propagation delay of 33 ns, making
this family ideal for applications where power consumption
and heat dissipation are the critical parameters.
LOW POWER SCHOTTKY (DM54LS/DM74LS and 54LS)
The low power Schottky family features a combined fivefold
reduction in current and power when compared to the TTL
family. Gold doping commonly used in the TTL devices reduces switching times at the expense of current gain. The
LS process overcomes this limitation by using a surface barrier diode (Schottky diode) in the baker clamp configuration
between the base and collector junction of the transistor. In
this way, the transistor is never fully saturated and recovers
quickly when base drive is interrupted. Using shallower diffusion and soft-saturating Schottky diode clamped transistors,
higher current gains and faster turn-on times are obtained.
The National LS circuits and a majority of the former Fairchild LS circuits do not use the mUlti-emitter inputs. They
use diode-transistor inputs which are faster and give increased input breakdown voltage; the input threshold is
-O.1V lower than TTL. A few'of the former Fairchild LS
circuits use the traditional emitter inputs and thus have input
breakdown ratings of 5.5V. These circuits are the open-collector gate types 'LS03, 'LS05, 'LS22 and 'LS136; flip-flop
types 'LS74, 'LS109, 'LS112 and 'LS113; and the clock inputs of the 'LS490. Another commonly used input is the
vertical substrate PNP transistor. In addition to fast switching, it exhibits very high impedance at both the high and low
input states, and the transistor's current gain CP) significantly reduces input loading and provides better output performance. The output structure is also modified with a Darlington
transistor pair to increase speed and improve drive capability. An active pull-down transistor (03) is incorporated to

TTL LOGIC (DM54/DM74) and (54xx)
TTL logic was the first saturating logic integrated circuit family introduced, thus setting the standard for all the future
families. It offers a combination of speed, power consumption, output source and sink capabilities suitable for most
applications. This family offers the greatest variety of logic
functions. The basic gate (see Figure 1) features a multipleemitter input configuration for fast switching speeds, active
pull-up output to provide a low driving source impedance
which also improves noise margin and device speed. Typical device power dissipation is 10 mW per gate and the
typical propagation delay is 10 ns when driving a 15
pF/4000 load.
LOW POWER TTL (DM54L)
The low power family has essentially the same circuit configuration as the TTL devices. The resistor values, however,
are increased by nearly tenfold, which results in tremendous
reduction of power dissipation to less than "'Ao of the TTL
family. Because of this reduction of power, the device speed

yield a symmetrical transfer characteristic (squaring network). This family achieves circuit performance exceeding
the standard TIL family at fractions of its power consumption. The typical device power dissipation is 2 mW per gate
and typical propagation delay is IOns while driving a 15 pF I
2 k!l load.

In addition to the pin-to-pin compatibility of the ALS family, a
large number of MSI and LSI functions are introduced in the
high density 24-pin 300 mil DIP. These devices offer the
designers greater cost effectiveness with the advantages of
reduced component count, reduced circuit board real-estate, increased functional capabilities per device and improved speed-power perfomance.
The basiC ALS gate schematic is quite similar to the LS
gate. It consists of either the PNP transistor or the diode
inputs, Darlington transistor pair pull-up and active pulldown (squaring network) at the output. Since the shallower
diffusions and thinner oxides will cause ALS devices to be
more susceptible to damage from electro-static discharge,
additional protection via a base-emitter shorted transistor is
included at the input for rapid discharge of high voltage static electricity. Furthermore, the inputs and outputs are
clamped by Schottky diodes to prevent them from swinging
excessively below ground level. A buried N + guard ring
around all input and output structures prevents crosstalk.
The ALS family has a typical power dissipation of 1 mW per
gate and typical propagation delay time of 4 ns into a
50 pF/2 k!l load.

SCHOTTKY (DM54S/DM74S)
This family features the high switching speed of unsaturated
bipolar emitter-coupled logic, but consumes more power
than standard TIL devices. To achieve this high speed, the
Schottky barrier diode is incorporated as a clamp to divert
the excess base current and to prevent the transistor from
reaching deep saturation. The Schottky gate input and internal circuitry resemble the standard TIL gate except the resistor values are about one-half the TTL value. The output
section has a Darlington transistor pair for pull-up and an
active pull-down squaring network. This family has power
dissipation of 20 mW per gate and propagation delays three
times as fast as TIL devices with the average time of 3 ns
while driving 15 pF/280!l load.
ADVANCED LOW POWER SCHOTTKY
(DM54ALS/DM74ALS)
The advanced low power Schottky family is one of the most
advanced TIL families. It delivers twice the data handling
efficiency and still provides up to 50% reduction in power
consumption compared to the LS family. This is possible
because of a new fabrication process where components
are isolated by a selectively grown thick-oxide rather than
the P-N junction used in conventional processes. This refined process, coupled with improved circuit design techniques, yields smaller component geometries, shallower diffusions, and lower junction capacitances. This enables the
devices to have increased fT in excess of 5 GHz and improved switching speeds by a factor of two, while offering
much lower operating currents.

ADVANCED SCHOTTKY (DM54AS/DM74AS)
This family of devices is designed to meet the needs of the
system deSigners who require the ultimate in speed. Utilizing Schottky barrier diode clamped transistors with shallower diffusions and advanced oxide-isolation fabrication techniques, the AS family achieves the fastest propagati.on delay that bipolar technology can offer. The AS family. has
virtually the same circuit configuration as the ALS family. It
has PNP transistor or diode inputs with electrostatic protection base-emitter shorted transistors. The output totem-pole
consists of a Darlington pair transistor pull-up and an active

pull-down squaring network. The inputs and outputs are
Schottky clamped to attenuate critical transmission line reflections. In addition, the circuit contains the "Miller Killer"
network at the output section to improve output rise time
and reduce power consumption during switching at high
repetition rates. The AS family yields typical power dissipation of 7 mW per gate and propagation delay time of 1.5 ns
when driving a 50 pF/2 kO load.

chip sizes are substantially reduced. The base and emitter
ends terminate in the oxide wall; masks can thus overlap
the device area into the isolation oxide. This overlap feature
eliminates the extremely close tolerances normally required
for base and emitter masking, and the standard photolithographic processes can be used.
SELECTING A FAMILY
Two factors shoud be considered when choosing a logic
family for application, speed and power consumption. New
logic families were created to improve the speed or lower
the power consumption of the previous families. The following tables rate each family.

FAST® TECHNOLOGY
FAST (Fairchild Advanced Schottky TTL) circuits are made
with the advanced isoplanar II process, which produces
transistors with very high, well-controlled switching speeds,
extremely small parasitic capacitances and fT in excess of
5 GHz. Isoplanar is an established National process, used
for years in the manufacture of bipolar memories. CMOS,

The combination of National Semiconductor and Fairchild
Semiconductor provides the largest selection of Bipolar
Logic Devices available anywhere. Recognizing that two of
the major product lines overlap-Low Power Schottky and
Standard TTL-both the Mill Aero and Commercial products
were consolidated so as to have the least impact on their
customers.

pie, the QUAD 2-INPUT NAND Gates, DM54LSOO and
54LSOO are both available. The former's performance is described by RET's (Reliability Electrical Test specifications);
and the latter's by a Table I. This is done to prevent considerable inconvenience to our customers who would have had
to modify their Source Control Drawings were a change
made to the device or its name.
While the datasheets in this databook do not describe the
full performance of the Mill Aero devices, the Table I and lor
the RET's do, and may be obtained through your local Field
Sales Offices or Representatives.
In terms of nomenclature, National Semiconductor uses the
prefix "OM" to represent all National-origin MillAero devices. The Fairchild-origin Mill Aero devices uses no "OM" prefix. Ordering information is included as well.

MilitaryI Aerospace Products
All of the MillAero MIL-STD-883 devices were maintained
for both National and Fairchild. In other words, the same
mask set, fab processes and electrical tests and specifications were continued for all devices previously made by
Fairchild Semiconductor as well as National Semiconductor,
whether there was duplication of a device or not. For examOM

Commercial Products
The majority of products in the Low Power Schottky,
Schottky and TTL logic families produced by National and
Fairchild are nearly identical in performance and considerably overlap in portfolio size. All of the sole source functions
were retained after the consolidation to minimize the impact

to our customers. Fairchild devices that remain in the logic
family portfolios are now designated by the National nomenclature. Where a Fairchild device was named 74LS373PC, it
will now be referenced to as a DM74LS373N. Please refer

eQ

Understanding the intent and practice of IC device testing is
vital to insuring both the quality and proper usage of integrated circuits. All National Semiconductor data sheets list
the AC and DC parameters with min and/or max limits,
along with forcing functions. Understanding when a part
fails the limit, and which forcing functions are really tighter,
is critical when determining if an IC device is good or bad.

Certain other devices will have "triple sink" outputs that can
drive 3 times the standard IOL and IOH currents. These devices are generally bus drivers, or drivers intended to drive
highly capacitive loads. Finally, there are certain devices
that have PNP inputs that reduce the IlL loading to typically
-200 /-LA, thus allowing an increased DC fan-in of 20. One
must therefore be careful when interfacing many different
types of devices, even in the same family, and not Simply go
the "fan-out of 10" rule.
When dealing with any kind of device specification, it is important to note that there exists a pair of test conditions that
define that test: the forcing function and the limit. Forcing
functions appear under the column labeled "Conditions"
and define the external operating constraints placed upon
the device tested. The actual test limit defines how well the
device responds to these constraints. For example, take the
parameter VOH(min) for the DM74LSOO. It is tested at
VCC(min) = 4.75V commercial, using an IOH = -400 /-LA. If
we required an IOH = -BOO /-LA, this would be a "tighter"
test, as the output voltage drops with increased IOH. Hence,
a device that would pass the -800 /-LA IOH would also pass
the - 400 /-LA IOH' but not necessarily the other way around.
Futhermore, VOH tracks with Vcc, which is why VCC(min) is
the worst-case testing, and not VCC(max)' Finally, forcing inputs to threshold represents the most difficult testing because this puts those inputs as close as possible to the
actual switching point and guarantees that the device will
meet the VIHIVIL spec.

All of National's databook parameters are defined and guaranteed for "worst-case testing." Input loading currents (fanin) are tested at the input and Vcc levels that most increase
that loading, while the output drive capability (fan-out) is
tested at the input and Vcc levels that most decrease that
capability. Icc is tested with the input conditions and Vcc
level that yield the greatest Icc value, and VCLAMP is tested
such that the negative voltage is maximized for the given
clamp current. The fan-in and fan-out specs are contained
in the IIH, IOH' IlL and IOL values. To guarantee these fan-in
and fan-out limits at 10, the IOL must be at least 10 times
the IlL and the IOH must be at least 10 times the IIH. Be
aware that the fan-in and fan-out specifications are valid
only within a given device family. The standard input loading
and output drives are shown in Table I.
Notice that the IOL is at least 10 times the IlL and that the
IOH is greater than 10 times the IIH. Also notice that these
are "standard" drive and load currents for single sink outputs and inputs. Certain devices may have multiple load inputs where the input line goes to several input structures
and has, say, 2 or 3 times the normal IlL and IIH loading.

Tables II and III show the "direction" of the looser/tighter
testing for most common DC parameters. Notice that one
can tighten either the forcing function or the limit, or both.
Tightening either one is sufficient to insure a tighter test.
Also notice the difference between max and min limits. For
los (double-ended limits), even though -20 mA is more
positive than -100 mA, and is mathematically the max limit,

the magnitude of the number is the determining factor when
deciding which is the max limit. The negative sign simply
implies the direction that the current is going, with a negative current leaving the device, and a positive current entering the device. Table II shows the direction of tighter forcing
functions, while Table III shows the direction of tighter limits.

measured. For typical LS products, the military and commercial test points are indicated on the VOL vs IOl graph. In
each case, the device must not exceed the VOL spec when
the IOl current is being forced.

The indicated graphs are typical of LS products and are
simi liar to other bipolar logic families. The schematics
shown are for single inversion devices and represent generalized circuits.

OUTPUT VOLTAGE HIGH LEVEL (VOH)
One input is tied high (any value above 2.0V) and the other
input is forced at the Vil threshold (assuming a single inversion gate). The minimum Vee value is used. Each input is
tested independently and the IOH current is forced. The resulting VOH is measured. The VOH vs IOH graph shows the
military and commercial VOH/IOH test points for standard
LS products.

OUTPUT VOLTAGE LOW LEVEL (Vou
Both inputs are connected to logic "1" values (assuming an
inverting gate) and forced at the VIH specs. Vee minimum is
used, and IOl is forced on the output. The resulting VOL is

INPUT CURRENT HIGH LEVEL (IIH)
IIH tests the input leakage in the high state. For MET, diode,
and PNP input, the test set-up consists of all inputs except
the one under test tied high (greater than VIH). The remaIning input has the VIH value forced upon it, and the resultant
IIH is measured. This test checks for emitter-to-collector inverse transistor action for MET inputs, and reverse bias
leakage for diode and PNP inputs.
For MET Inputs, there is also an additional set-up for IIH
testing that checks for emitter-to-emitter transistor action.
This is done with all the other inputs tied to ground.

INPUT CURRENT LOW LEVEL (In)
One input at a time is tested with the other inputs tied to a
solid "1" value~Vcc is set to the maximum value and the
VIL value is forced. IlL is then measured.

MAXIMUM INPUT CURRENT (II)
liar BVIN testing is the same as the emitter-to-collector
leakage test (IIH) and guarantees that the input will not pass
more than the specified current at the stated specification
(100 /LA at 7V for LS).

IlL is intended to measure the value of the base pull-up resistor on the input, and to guarantee the maximum input
load an Ie presents.

OUTPUT SHORT CIRCUIT CURRENT (lOS)
loS is measured with VCC(max) and the OV forced on the
output while it is in the high state. The resultant current Is
measured. The purpose of this is to check the los resistor
that forms the Darlington's collector pull-up. This parameter
is important as it reflects both the maximum current the device will draw and the maximum drive it will provide when it
is switching from low to high.
Caution must be taken when measuring TTL, LS and S outputs as the power dissipated on the die will be substantial.
los shorts should not be maintained in excess of one second or damage to the device may result.

SUPPLY CURRENT HIGH LEVEL (ICCH) AND SUPPLY
CURRENT LOW LEVEL (ICCl)
Both ICCH and leeL are tested using the Vee maximum value. The inputs are set to the values necessary to achieve
the output in the desired state. All outputs are left open,
neither sourcing nor sinking current. The goal of this test is
to guarantee the maximum quiescent operating power that
the device will draw.

AC SWITCHING CHARACTERISTICS
The AC switching characteristics are generally measured in
units of time (commonly in nanoseconds), and define how
long it takes for the signal to propagate from the input to the
output. The definitions used in determining the pass/fail
status of each limit are not the same for AC as they are for
DC. The distinction lies in the fact that for DC operation
there exists one characteristic V-I curve on which the device
must operate. Devices are good if they operate on the correct side of the limit, and bad if they operate on the wrong
side of the limit. When dealing with certain AC parameters
(fMAX, tSET-UP tHOLD tRELEASE tpw), the device can, and
usually does, operate on both sides of the databook limit.
The limit really implies a boundary that all devices are guaranteed to exceed. Depending upon the parameter, the device will either operate at all values above and some below
the limit, or it will operate at all values below and some
above the limit. In each case, the device is only guaranteed
to operate for all values on one side of the limit. Although
the device will also operate beyond the limit, it is not guaranteed to. Furthermore, device operation beyond the limit is
not considered a failure. For instance, take the fMAX parameter with a min limit of 25 MHz. All devices are guaranteed
to operate at all frequencies below 25 MHz and will operate
in excess of 25 MHz, although this is not guaranteed. Now,
take the example of tSET-UP with a minimum limit of 25 ns.
All of the devices are guaranteed to operate with a set-up
time of 25 ns and longer, and will operate with set-up times
below 25 ns, although this is not guaranteed either. Be
aware that both of these specifications are listed in the minimum column in the databook, but the interpretation of what
is failing differs significantly.

ICEX Is tested with the output in the high state. Vee is set to
5.0V and the specified voltage (5.5V for LS) is applied to the
output. The inputs are at the threshold values (O.8V and
2.0V, depending upon the logic to put output in the high
state) and the resulting ICEX leakage current is measured.

Propagation delays (called prop delays and denoted by the
symbols tpHL and tPLH) are specified as maximum limits,
and guarantee the maximum time one must wait to insure
that the correct data has appeared at the device's output.
Each propagation delay is specified from one input to one
output only.

TUF16731-25

Vee MAX

I

Input set-up and hold times (including tRELEASE) specify
how long one input must be stable at a particular logic level
prior to an action occurring at another input. For example,
take the DM54174LS74 positive-edge-triggered D flip-flop.
The "set-up 1" specification defines how long a logic "1"
must be present and stable at the DATA input prior to the
positive edge of the CLOCK to insure that the device will
recognize that data as a "1". There also exists a "hold 1"
specification which specifies how long a logic "1" must be
held after the active edge of CLOCK for the device to recognize that logic "1". Both the set-up and hold times must
always be met or the device will not necessarily bring in the
proper data. Set-up times are generally pOSitive, while hold

times may be either positive or negative, usually negative.
The meaning of a negative hold time Is that the data may be
removed from the Input prior to the active edge of CLOCK,
and the CLOCK will still bring in the desired data. Set-up
and hold times are speciflad as minimum values, since this
defines the minimum time data must be stable prior to any
change at the CLOCK input. Removing the data sooner than
the minimum time may cause improper action on the part of
the device.
tRELEASE is specified on devices where there is an input
that must be set inactive prior to the active edge of CLOCK.
Such inputs are usually overriding inputs like CLEAR and
PRESET. With CLEAR active, it will prevent the device from
switching on the CLOCK signal. tRELEASE is defined as the
time it takes for the CLEAR input to "release" the device for
clocking action, and is specified as a minimum. This represents the maximum delay required between CLEAR going
inactive and the active edge of CLOCK to insure proper
device operation.
All devices that have a CLOCK input also have a specification that defines the maximum speed that the CLOCK can
be driven, called fMAX. This specification is defined as a
minimum specification and states that all of the devices will

be able to operate at frequencies up to 25 MHz. For the
DM54/74LS74 with an fMAX of 25 MHz, all of the devices
are guaranteed to operate at all clock frequencies, up to
and including 25 MHz. Aithough no devices are guaranteed
to operate above fMAX (only below it), most devices will
operate beyond the maximum speCification. The minimum
limit does not state that the device will not operate below
fMAX or that any devices that do are bad, but rather that all
the devices will operate up to the limit.
Table IV shows the direction of the tighter testing for the
more common AC parameters. All prop dealys (those AC
parameters that have the symbols tpLH or tpHU have simple
minImax limits. The device is guaranteed to operate within
the bounds of the minImax limits, and any operation outside
these limits denotes a device failure. tSET-UP, tHOLD, fMAX,
and tRELEASE parameters have limits that denote guaranteed operation boundaries (i.e., the device is guaranteed to
operate up to the boundary) but no guarantee is made concerning the device operation (or lack of it) beyond the
boundary.
For detailed information on the AC waveforms, please see

Glossary of Terms

DC Operating Conditions and Characteristics
GENERAL DEFINITIONS

OUTPUT CURRENT PARAMETERS

I: Current is the flow of electric charge from one potential to
another through a conductor. The unit of measure is the
Ampere, or Amp, abbreviated A. One Amp is equal to the
current flowing through one ohm of resistance when one
volt is applied across that resistance. Common units found
in the semiconductor industry are the milliampere, abbreviated mA, equal to 0.001A and the microampere, abbreviated p.A, equal to 0.000001 A. Negative current is defined as
current flowing out of a device terminal and positive current
is defined as current flowing into a device terminal.

ICEX Output Leakage Current: The current flowing into an
open collector output when input conditions have been applied that, according to the product specification, will cause
the output to be in the logic high state. This test checks the
reverse breakdown of the output transistor.
lo(off) OffoState Output Current: The current flowing into
an output with input conditions applied that, according to the
product specification, will cause the output switching element to be in the off state.
NOTE: This parameter is usually specHied for open collector outputs Intend·
ed to drive devices other than logic circuits, such as displays. Any
leakage current applied to a display may cuase the display to be
activated.

V: Voltage, or the electromotive force which causes current
to flow through a conductor. One Ampere of current flowing
through one ohm of resistance develops a potential difference of one volt across that resistance. The unit of measure
is the Volt, abbreviated V, and a common unit is the millivolt,
abbreviated mV, equal to O.OOW.

10H High Level Output Current: The current flowing out of
an output with input conditions applied that, according to the
product specification, will establish a logic high level at the
output. This test guarantees the current sourcing (drive) capability of the output and the fan-out specified for the family.

INPUT CURRENT PARAMETERS
II Maximum High Level Input Current: Current flowing into
an input when that input has the maximum voltage specified
for the family applied to it. This test is used to guarantee the
minimum reverse breakdown voltage of the input structure.

10L Low Level Output Current: The current flowing into an
output with input conditions applied that, according to the
product specification, will establish a logic low level at the
output. This test guarantees the current sinking capability of
the output and the fan-out specified for the family.

IIH High Level Input Current: The current flowing into an
input when that input has a high level voltage equal to the
minimum high level output voltage specified for the family.
This test is used to check the emitter-to-emitter leakage and
the inverse transistor action of a multi-emitter transistor input, the input leakage of a diode, PNP transistor, or CoB
short type of input, and to guarantee the fan-in specified for
the family.

los Output Short-CIrcuit Current: The current out of an
output when that output is shorted to ground, or another
specified potential, with input conditions applied that, according to the product specification, will establish a logiC
high level at the output.
loz High-Impedance State Output Current: These tests
guarantee that the device will not excessively load a bus
line when the device output is put into the TRI-STATE~
mode.

11K Input Clamp Current: The current flowing out of an input when that input is pulled below ground. This test is used
to guarantee the integrity of the input clamp diode. The input
clamp diode is used to limit the voltage swings on the input
by clamping the negative excursions to a level equal to one
diode drop below ground. This serves to reduce ringing on
an incoming Signal. Pulling the input below ground for an
extended length of time can cause parasitic transistor action
to occur between adjacent tanks on the die which can
cause erroneous data to occur on the outputs of the device.
To prevent this, voltages on the inputs during operation
(other than high speed ringing) should be limited to no more
than O.SV below ground at all times.

10ZH (or ISINK>: The current flowing into an output with input
conditions applied to the output control pin such that the
output is in the high impedance state and input conditions
applied to the other inputs that, according to the product
specification, will establish a logic low level at the output.

Functional Description
The 'LS47 decodes the Input data in the pattern Indicated in
the Truth Table and the segment identification illustration. If
the input data is decimal zero, a LOW signal applied to the
RBI blanks the display and causes a multidiglt display. For
example, by grounding the RBI of the highest order decoder
and connecting its BI/RBO to RBI of the next lowest order
decoder, etc., leading zeros will be suppressed. Similarly, by
grounding RBI of the lowest order decoder and connecting
Its BIIRBO to RBi of the next highest order decoder, etc.,
trailing zeros will be suppressed. Leading and trailing zeros
can be suppressed simultaneously by using external gates,
i.e.: by driving RBI of a intermediate decoder from an OR

gate whose Inputs are BIIABO of the next highest and lowest order decoders. Bi7RBO also serves as an unconditional blanking input. The internal NAND gate that generates
the RBO signal has a resistive pull-up, as opposed to a
totem pole, and thus BIIABO can be forced LOW by external means, using wired-collector logic. A LOW Signal thus
applied to BIIABO turns off all segment outputs. This blanking feature can be used to control display intensity by varying the duty cycle of the blanking Signal. A LOW Signal applied to LT turns on all segment outputs, provided that
BIIRBO is not forced LOW.

Note 1: Bl7li!ro is wire-AND logic serving as blanking Input (iii) andlor ripple-blanking output (ABO). The blanking out (ill) must be open or held at a HIGH level
when output functions 0 through 15 are desired, and ripple-blanking Input (RBi) must be open or at a HIGH level If blanking or a decimal 0 Is not desired. X = input
may be HIGH or LOW.
Note 2: When a LOW levalls applied to the blanking Input (forced condition) all segment outputs go to a HIGH level regardless of the state of any other input
condition.
Note 3: When ripple-blanking input (i'iBi) and inputs AO, AI, A2 and A3 are LOW level, with the lamp test input at HIGH level, all segment outputs go to a HIGH
leval and the ripple-blanking output (ABO) goes to a LOW level (response condition).
Note 4: When the blanking Input/ripple-blanking output (Bl7li!ro) is open or held at a HIGH level, and a LOW level Is applied to lamp test Input, all segment outputs
go to a LOW level.

DM54LS73A/DM74LS73A Dual Negative-Edge-Triggered
Master-Slave J-K Flip-Flops with Clear
and Complementary Outputs
General Description
This device contains two independent negative-edge-triggered J-K flip-flops with complementary outputs. The J and
K data is processed by the flip-flops on the falling edge of
the clock pulse. The clock triggering occurs at a voltage
level and is not directly related to the transition time of the
negative going edge of the clock pulse. The data on the J

and K inputs is allowed to change while the clock is high or
low without affecting the outputs as long as setup and hold
times are not violated. A low logic level on the clear input
will reset the outputs regardless of the levels of the other
inputs.

DM54LS75/DM74LS75 Quad Latches
General Description
These latches are ideally suited for use as temporary storage for binary information between processing units and input/output or indicator units. Information present at a data
(D) input is transferred to the
output when the enable is
high, and the output will follow the data input as long as
the enable remains high. When the enable goes low,

the information (that was present at the data input at the
time the transition occured) is retained at the output until
the enable is permitted to go high.
These latches feature complementary
and 0 outputs
from a 4-bit latch, and are available in 16-pin packages.

54LS83A/DM54LS83A/DM74LS83A
4-Bit Binary Adders with Fast Carry
General Description

Features

These full adders perform the addition of two 4-bit binary
numbers. The sum (l:) outputs are provided for each bit and
the resultant carry (C4) is obtained from the fourth bit.
These adders feature full internal look ahead across all four
bits. This provides the system designer with partial lookahead performance at the economy and reduced package
count of a ripple-carry implementation.
The adder logic, including the carry, is implemented in its
true form meaning that the end-around carry can be accomplished without the need for logic or level inversion.

• Full-carry look-ahead across the four bits
• Systems achieve partial look-ahead performance with
the economy of ripple carry
• Typical add times
Two 8-bit words 25 ns
Two 16-bit words 45 ns
• Typical power dissipation per 4-bit adder 95 mW
• Alternate Military/Aerospace device (54LS83A) is available. Contact a National Semiconductor Sales Office/
Distributor for specifications.

6. The retriggerable pulse width is calculated as shown below:

8. Under any operating condition Cx and Rx must be kept
as close to the one-shot device pins as possible to minimize stray capacitance, to reduce noise pick-up, and to
reduce I-R and Ldildt voltage developed along their connecting paths. If the lead length from Cx to pins (13) and
(11) is greater than 3 cm, for example, the output pulse
width might be quite different from values predicted from
the appropriate equations. A non-inductive and low capacitive path is necessary to ensure complete discharge
of Cx in each cycle of its operation so that the output
pulse width will be accurate.
9. Vee and ground wiring should conform to good high-frequency standards and practices so that switching transients on the Vcc and ground return leads do not cause
interaction between one-shots. A 0.01 /-LF to 0.10 /-LF bypass capaCitor (disk ceramic or monolithic type) from Vee
to ground is necessary on each device. Furthermore, the
bypass capaCitor should be located as close to the Vee
pin as space permits.

T = Tw + tpLH = 0.50 x Rx x Cx + TpLH
The retriggered pulse width is equal to the pulse width
plus a delay time period (Figure 4).

DM7 4LS 123 Dual Retriggerable One-Shot
with Clear and Complementary Outputs
General Description
The DM74LS123 is a dual retriggerable monostable multivibrator capable of generating output pulses from a few nanoseconds to extremely long duration up to 100% duty cycle.
Each device has three Inputs permitting the choice of either
leading edge or trailing edge triggering. Pin (A) is an activelow transition trigger input and pin (8) is an active-high transition trigger input. The clear (CLR) input terminates the output pulse at a predetermined time independent of the timing
components. The clear input also serves as a trigger input
when it is pulsed with a low level pulse transition (l...f'). To
obtain the best trouble free operation from this device
please read the operating rules as well as the NSC one-shot
application notes carefully and observe recommendations.

The basic output pulse width is determined by selection of
an external resistor (Rx) and capaCitor (Cx). Once triggered,
the basic pulse width may be extended by retriggering the
gated active-low transition or active-high transition inputs or
be reduced by use of the active-low or CLEAR input. Retrlggering to 100% duty cycle is possible by application of an
input pulse train whose cycle time Is shorter than the output
cycle time such that a continuous "HIGH" logic state is
maintained at the "a" output.

• DC triggered from active-high transition or active-low
transition inputs
• Retriggerable to 100% duty cycle

Operating Rules
4. The multiplicative factor K is plotted as a function of Cx
below for design considerations:
100 ~F

1. An external resistor (Rx) and an external capacitor (Cx)
are required for proper operation. The value of Cx may
vary from 0 to any necessary value. For small time constants high-grade mica, glass, polypropylene, polycarbonate, or polystyrene material capacitors may be used. For
large time constants use tantalum or special aluminum
capacitors. If the timing capacitors have leakages approaching 100 nA or if stray capacitance from either terminal to ground is greater than 50 pF the timing equations
may not represent the pulse width the device generates.

103 pF

2. When an electrolytic capacitor is used for Cx a switching
diode is oiten required for standard TTL one-shots to prevent high inverse leakage current. This switching diode is
not needed for the 'LS123 one-shot and should not be
used. In general the use of the switching diode is not
recommended with retriggerable operation.

TL/F/6386-5

FIGURE 6
9. Under any operating condition Cx and Rx must be kept
as close to the one-shot device pins as possible to minimize stray capacitance, to reduce noise pick-up, and to
reduce I-R and Ldildt voltage developed along their
connecting paths. If the lead length from Cx to pins (6)
and (7) or pins (14) and (15) is greater than 3 cm, for
example, the output pulse width might be quite different
from values predicted from the appropriate equations. A
non-inductive and low capacitive path is necessary to
ensure complete discharge of Cx in each cycle of its
operation so that the output pulse width will be accurate.
10. The CEXT pins of this device are internally connected to
the internal ground. For optimum system performance
they should be hard wired to the system's return ground
plane.
11. Vee and ground wiring should conform to good high-frequency standards and practices so that switching transients on the Vee and ground return leads do not cause
interaction between one-shots. A 0.01 /-LF to 0.10 /-LF
bypass capacitor (disk ceramic or monolithic type) from
Vee to ground is necessary on each device. Furthermore, the bypass capacitor should be located as close
to the Vee-pin as space permits.
For further detailed device characteristics and output pertonnance
please rater to the NSC one-ahot application note AN-336.

Quad TRI-STATE® Buffers
General Description
that two outputs will attempt to take a common bus to opposite logic levels, the disable time is shorter than the enable
time of the outputs.

This device contains four independent gates each of which
performs a non-inverting buffer function. The outputs have
the TRI-STATE feature. When enabled, the outputs exhibit
the low impedance characteristics of a standard LS output
with additional drive capability to permit the driving of bus
lines without external resistors. When disabled, both the
output transistors are turned off presenting a high-impedance state to the bus line. Thus the output will act neither as
a significant load nor as a driver. To minimize the possibility

54LS 138/DM54LS 138/DM74LS 138,
54LS 139/DM54LS 139/DM74LS 139
Decoders/Demultiplexers
General Description
These Schottky-clamped circuits are designed to be used in
high-performance memory-decoding or data-routing applications, requiring very short propagation delay times. In
high-performance memory systems these decoders can be
used to minimize the effects of system decoding. When
used with high-speed memories, the delay times of these
decoders are usually less than the typical access time of the
memory. This means that the effective system delay introduced by the decoder is negligible.
The LS138 decodes one-of-eight lines, based upon the conditions at the three binary select inputs and the three enable
inputs. Two active-low and one active-high enable inputs
reduce the need for external gates or inverters when expanding. A 24-line decoder can be implemented with no external inverters, and a 32-line decoder requires only one
inverter. An enable input can be used as a data input for
demultiplexing applications.
The LS139 comprises two separate two-line-to-four-line decoders in a single package. The active-low enable input can
be used as a data line in demultiplexing applications.
All of these decoders/demultiplexers feature fully buffered
inputs, presenting only one normalized load to its driving
circuit. All inputs are clamped with high-performance

Schottky diodes to suppress line-ringing and simplify system
design.

Features
• Designed specifically for high speed:
Memory decoders
Data transmission systems
• LS138 3-lo-8-line decoders incorporates 3 enable inputs to simplify cascading and/or data reception
• LS139 contains two fully independent 2-to-4-line decoders/demultiplexers
• Schottky clamped for high performance
• Typical propagation delay (3 levels of logiC)
LS138 21 ns
LS139 21 ns
• Typical power dissipation
LS138 32 mW
LS139 34 mW
• Alternate
Military/Aerospace
devices
(54LS138,
54LS139) are available. Contact a National Semiconductor Sales Office/ Distributor for specifications.

DM54LS154/DM74LS154 4-Line to 16-Line
Decoders/Demultiplexers
General Description

Features

Each of these 4-line-to-16-lIne decoders utilizes TTL circuitry to decode four binary-coded inputs into one of sixteen
mutually exclusive outpu1s when both the strobe inputs, G1
and G2, are low. The demultiplexing function Is performed
by using the 4 input lines to address the output line, passing
data from one of the strobe inputs with the other strobe
input low. When either strobe input is high, all outputs are
high. These demultiplexers are ideally suited for implementing high-performance memory decoders. All inputs are buffered and input clamping diodes are provided to minimize
transmission-line effects and thereby simplify system design.

• Decodes 4 binary-coded inputs into one of 16 mutually
exclusive outputs
• Performs the demultiplexing function by distributing data
from one input line to anyone of 16 outputs
• Input clamping diodes simplify system design
• High fan-out, low-impedance, totem-pole outputs
• Typical propagation delay
3 levels .of logic 23 ns .
Strobe 19 ns
• Typical power dissipation 45 mW

Dual 2-Line to 4-Line Decoders/Demultiplexers

en

General Description

Features

These TIL circuits feature dual 1-line-to-4-line demultiplexers with individual strobes and common binary-address inputs in a single 16-pin package. When both sections are
enabled by the strobes, the common address inputs sequentially select and route associated input data to the appropriate output of each section. The individual strobes permit activating or inhibiting each of the 4-bit sections as desired. Data applied to input C1 is inverted at its outputs and
data applied at C2 is true through its outputs. The inverter
following the C1 data input permits use as a 3-to-B-line decoder, or 1-to-B-line demultiplexer, without external gating.
Input clamping diodes are provided on these circuits to minimize transmission-line effects and simplify system design.

• Applications:
Dual 2-to-4-line decoder
Dual 1-to-4-line demultiplexer
3-to-B-line decoder
1-to-B-line demultiplexer
• Individual strobes simplify cascading for decoding or
demultiplexing larger words
• Input clamping diodes simplify system design
• Choice of outputs:
Totem-pole (LS155)
Open-collector (LS156)
• Alternate Military/Aerospace device (54LS155/156) is
available. Contact a National Semiconductor Sales Office/Distributor for specifications.

Synchronous Presettable BCD Decade Counters
General Description

Features

The 'LS160 and 'LS162 are high speed synchronous decade counters operating in the BCD (8421) sequence. They
are synchronously presettable for application in programmable dividers and have two types of Count Enable inputs plus
a Terminal Count output for versatility in forming synchronous multistage counters. The 'LS160 has an asynchronous
Master Reset input that overrides all other inputs and forces
the outputs LOW. The 'LS162 has a Synchronous Reset
input that overrides counting and parallel loading and allows
all outputs to be simultaneously reset on the rising edge of
the clock.

Functional Description
The 'LS160 and 'LS162 count modulo-10 in the BCD (8421)
sequence. From state 9 (HLLH) they increment to state 0
(LLLL). The '161 and '163 count modul0-16 binary sequence. From state 15 (HHHH) they increment to state 0
(LLLL). The clock inputs of all flip-flops are driven in parallel
through a clock buffer. Thus all changes of the a outputs
(except due to Master Reset of the 'LS160) occur as aresuit of, and synchronous with, the LOW-to-HIGH transition
of the CP input signal. The circuits have four fundamental
modes of operation, in order of precedence: asynchronous
reset (,LS160), synchronous reset ('LS162), parallel load,
count-up and hold. Five control inputs-Master Reset (MR,
'LS160), Synchronous Reset (SR, 'LS162), Parallel Enable
(PE), Count Enable Parallel (CEP) and Count Enable Trickle
(CET}-determine the mode of operation, as shown in the

Mode Select Table. A LOW signal on MR overrides all other
inputs and asynchronously forces all outputs LOW. A LOW
signal on SR overrides counting and parallel loading and
allows all outputs to go LOW on the next rising edge of CPo
A LOW Signal on PE overrides counting and allows information on the Parallel Data (P n) inputs to be loaded into the
flip-flops on the next rising edge of CPo With PE and MR
('LS160) or SR ('LS162) HIGH, CEP and CET permit counting when both are HIGH. Conversely, a LOW signal on either CEP or CET inhibits counting.
The 'LS160A and 'LS162A use D-type edge-triggered flipflops and changing the SR, PE, CEP and CET inputs when
the CP is in either state does not cause errors, provided that
the recommended setup and hold times, with respect to the
rising edge of CP, are observed.

2-177

Functional Description (Continued)
The Terminal Count (TC) output is HIGH when CET is HIGH
and the counter is in its maximum count state (9 for the
decade counters, 15 for the binary counters). To implement
synchronous multistage counters, the TC outputs can be
used with the CEP and CET inputs in two different ways.

Mode Select Table

These two schemes are shown in the 9310 data sheet. The
TC output is subject to decoding spikes due to internal race
conditions and is therefore not recommended for use as a
clock or asynchronous reset for flip-flops, counters or registers. In the decade counters of the 'LS160, 'LS162, the TC
output is fully decoded and can only be HIGH in state 9.

54LS 163A/DM54LS 163A/DM74LS 163A
Synchronous 4-Bit Binary Counters
General Description
These synchronous, presettable counters feature an internal carry look-ahead for application in high-speed counting
designs. The LS161A and LS163A are 4-bit binary counters.
The carry output is decoded by means of a NOR gate, thus
preventing spikes during the normal counting mode of operation. Synchronous operation is provided by having all flipflops clocked simultaneously so that the outputs change coincident with each other when so instructed by the countenable inputs and internal gating. This mode of operation
eliminates the output counting spikes which are normally
associated with asynchronous (ripple clock) counters. A
buffered clock input triggers the four flip-flops on the rising
(positive-going) edge of the clock input waveform.
These counters are fully programmable; that is, the outputs
may be preset to either level. As presetting is synchronous,
setting up a low level at the load input disables the counter
and causes the outputs to agree with the setup data after
the next clock pulse, regardless of the levels of the enable
input. Low-to-high transitions at the load input are perfectly
acceptable, regardless of the logic levels on the clock or
enable inputs. The clear function for the LS161A is asynchronous; and a low level at the clear input sets all four of
the flip-flop outputs low, regardless of the levels of clock,
load, or enable inputs. The clear function for the LS163A is
synchronous; and a low level at the clear inputs sets all four
of the flip-flop outputs low after the next clock pulse, regardless of the levels of the enable inputs. This synchronous
clear allows the count length to be modified easily, as decoding the maximum count desired can be accomplished
with one external NAND gate. The gate output is connected
to the clear input to synchronously clear the counter to all
low outputs.

The carry look-ahead circuitry provides for cascading counters for n-bit synchronous applications without additional
gating. Instrumental in accomplishing this function are two
count-enable inputs and a ripple carry output.
must be high to count,
Both count-enable inputs (P arid
and input T is fed forward to enable the ripple carry output.
The ripple carry output thus enabled will produce a high-level output pulse with a duration approximately equal to the
high-level portion of the QA output. This high-level overflow
ripple carry pulse can be used to enable successive cascaded stages. High-to-Iow level transitions at the enable P or T
inputs may occur, regardless of the logiC level of the clock.

n

These counters feature a fully independent clock circuit.
Changes made to control inputs (enable P or T or load) that
will modify the operating mode have no effect until clocking
occurs. The function of the counter (whether enabled, disabled, loading, or counting) will be dictated solely by the
conditions meeting the stable set-up and hold times.

a-Bit Serialln/Paraliel Out Shift Registers
General Description

Features

These 8-bit shift registers feature gated serial inputs and an
asynchronous clear. A low logic level at either input inhibits
entry of the new data, and resets the first flip-flop to the low
level at the next clock pulse, thus providing complete control over incoming data. A high logic level on either input
enables the other input, which will then determine the state
of the first flip-flop. Data at the serial inputs may be changed
while the clock is high or low, but only information meeting
the setup and hold time requirements will be entered. Clocking occurs on the low-to-high level transition of the clock
input. All inputs are diode-clamped to minimize transmission-line effects.

54LS 165/DM7 4LS 165 a-Bit Parallel
In/Serial Output Shift Registers
General Description
This device is an 8-bit serial shift register which shifts data in
the direction of QA toward QH when clocked. Parallel-in access is made available by eight individual direct data inputs,
which are enabled by a low level at the shift/load input.
These registers also feature gated clock inputs and complementary outputs from the eighth bit.
Clocking is accomplished through a 2-input NOR gate, permitting one input to be used as a clock-inhibit function. Holding either of the clock inputs high inhibits clocking, and holding either clock input low with the load input high enables
the other clock input. The clock-inhibit input should be
changed to the high level only while the clock input is high.
Parallel loading is inhibited as long as the load input is high.

Connection Diagram

Data at the parallel inputs are loaded directly into the register on a high-to-Iow transition of the shift/load input, regardless of the logic levels on the clock, clock inhibit, or serial
inputs.

8-Bit Paraliel-ln/Serial-Out Shift Registers
General Description
These parallel-in or serial-in, serial-out shift registers feature
gated clock inputs and an overriding clear input. All inputs
are buffered to lower the drive requirements to one normalized load, and input clamping diodes minimize switching
transients to simplify system design. The load mode is established by the shift/load input. When high, this input enables the serial data input and couples the eight flip-flops for
serial shifting with each clock pulse. When low, the parallel
(broadside) data inputs are enabled and synchronous loading occurs on the next clock pulse. During parallel loading,
serial data flow is inhibited. Clocking is accomplished on

the low-to-high-Ievel edge of the clock pulse through a twoinput NOR gate, permitting one input to be used as a clockenable or clock-inhibit function. Holding either of the clock
inputs high inhibits clocking; holding either low enables the
other clock input. This allows the system clock to be free
running, and the register can be stopped on command with
the other clock input. The clock-inhibit input should be
changed to the high level only while the clock input is high.
A buffered, direct clear input overrides all other inputs, including the clock, and sets all flip-flops to zero.

4 x 4 Register File with Open-Collector Outputs
General Description

Features

The 'LS170 contains 16 high speed, low power, transparent
D-type latches arranged as four words of four bits each, to
function as a 4 x 4 register file. Separate read and write
inputs, both address and enable, allow simultaneous read
and write operation. Open-collector outputs make it possible
\0 connect up to 128 outputs in a wired-AND configuration
to increase the word capacity up to 512 words. Any number
of these devices can be operated in parallel to generate an
n-blt length. The '670 provides a similar function to this device but it features TRI-STATEQI) outputs.

TRI-STATE® 4-Bit D-Type Register
General Description
This four-bit register contains D-type flip-flops with totempole TRI-STATE~ outputs, capable of driving highly capacitive or low-impedance loads. The high-impedance state and
increased high-logic-level drive provide these flip-flops with
the capability of driving the bus lines in a bus-organized system without need for interface or pull-up components.

To minimize the possibility that two outputs will attempt to
take a common bus to OPPOSite logic levels, the output control circuitry is designed so that the average output disable
times are shorter than the average output enable times.

Gated enable inputs are provided for controlling the entry of
data into the flip-flops. When both data-enable inputs are
low, data at the 0 inputs are loaded into their respective flipflops on the next positive transition of the buffered clock
Input. Gate output control inputs are also provided. When
both are low, the normal logic states of the four outputs are
available for driving the loads or bus lines. The outputs are
disabled independently from the level of the clock by a high
logic level at either output control input The outputs then
present a high impedance and neither load nor drive the bus
line. Detailed operation is given in the truth table.

• TRI-STATE outputs interface directly with system bus
• Gated output control lines for enabling or disabling the
outputs
• Fully independent clock eliminates restrictions for operating in one of two modes:

Hex/Quad D Flip-Flops with Clear
General Description

Features

These positive-edge-triggered flip-flops utilize TTL circuitry
to implement D-type flip-flop logic. All have a direct clear
input, and the quad (175) versions feature complementary
outputs from each flip-flop.
Information at the D inputs meeting the setup time requirements Is transferred to the 0 outputs on the positive-going
edge of the clock pulse. Clock triggering occurs at a particular voltage level and Is not directly related to the transition
time of the positive-going pulse. When the clock input is at
either the high or low level, the D Input signal has no effect
at the output.

Functional Description
The 'LS181 is a 4-bit high speed parallel Arithmetic Logic
Unit (ALU). Controlled by the four Function Select inputs
(SO-S3) and the Mode Control input (M), it can perform all
the 16 possible logic operations or 16 different arithmetic
operations on active HIGH or active LOW operands. The
Function Table lists these operations
When the Mode Control input (M) is HIGH, all internal carries are inhibited and the device performs logic operations
on the individual bits as listed. When the Mode Control input
is LOW, the carries are enabled and the device performs
arithmetic operations on the two 4-bit words. The device
incorporates full internal carry lookahead and provides for
either ripple carry between devices using the Cn + 4 output,
or for carry lookahead between packages using the signals
P (Garry Propagate) and G (Carry Generate). In the ADD
mode, P indicates that F is 15 or more, while G indicates
that F is 16 or more. In the SUBTRACT mode, P indicates
that F is zero or less, while G indicates that F is less than
zero. P and G are not affected by carry in. When speed
requirements are not stringent, it can be used in a simple
ripple carry mode by connecting the Carry output (Cn+ 4)
signal to the Carry input (Cn) of the next unit. For high speed
operation the device is used in conjunction with the 9342 or
93S42 carry lookahead circuit. One carry lookahead pack-

age is required for each group of four 'LS181 devices. Carry
lookahead can be provided at various levels and offers high
speed capability over extremely long word lengths.
The A = B output from the device goes HIGH when all four
F outputs are HIGH and can be used to indicate logiC equivalence over four bits when the unit is in the subtract mode.
The A = B output is open-collector and can be wired-AND
with other A = B outputs to give a comparison for more
than four bits. The A = B signal can also be used with the
Cn +4 signal to indicate A> B and A < B.
The Function Table lists the arithmetic operations that are
performed without a carry in. An incoming carry adds a one
to each operation. Thus, select code LHHL generates A
minus B minus 1 (2s complement notation) without a carry
in and generates A minus B when a carry is applied. Because subtraction is actually performed by complementary
addition (1 s complement), a carry out means borrow; thus a
carry is generated when there is no underflow and no carry
is generated when there is underflow. As indicated, this device can be used with either active LOW inputs producing
active LOW outputs or with active HIGH inputs producing
active HIGH outputs. For either case the table lists the operations that are performed to the operands labeled inside the
logiC symbol.

Synchronous 4-Bit Up/Down Counters with Mode Control
General Description
These circuits are synchronous, reversible, up/down counters. The LS191 is a 4-bit binary counter and the LS190 is a
BCD counter. Synchronous operation Is provided by having
all flip-flops clocked simultaneously, so that the outputs
change simultaneously when so Instructed by the steering
logic. This mode of operation eliminates the output counting
spikes normally associated with asynchronous (ripple clock)
counters.
The outputs of the four master-slave flip-flops are triggered
on a low-to-high level transition of the clock input, if the
enable input is low. A high at the enable input inhibits counting. Level changes at either the enable input or the down/
up input should be made only when the clock input is high.
The direction of the count is determined by the level of the
down/up input. When low, the counter counts up and when
high, it counts down.
These counters are fully programmable; that is, the outputs
may be preset to either level by placing a low on the load
input and entering the desired data at the data inputs. The
output will change independent of the level of the clock input. This feature allows the counters to be used as moduloN dividers by simply modifying the count length with the
preset inputs.
The clock, down/up, and load inputs are buffered to lower
the drive requirement; which significantly reduces the number of clock drivers, etc., required for long parallel words.

Two outputs have been made available to perform the cascading function: ripple clock and maximum/minimum count.
The latter output produces a high-level output pulse with a
duration approximately equal to one complete cycle of the
clock when the counter overflows or underflows. The ripple
clock output produces a low-level output pulse equal in
width to the low-level portion of the clock input when an
overflow or underflow condition exists. The counters can be
easily cascaded by feeding the ripple clock output to the
enable input of the succeeding counter if parallel clocking Is
used, or to the clock input if parallel enabling is used. The
maximum/minimum count output can be used to accomplish look-ahead for high-speed operation.

54LS192/DM74LS192 Up/Down Decade Counter
with Separate Up/Down Clocks
General Description
The 'LS192 is an up/down BCD decade (8421) counter.
Separate Count Up and Count Down Clocks are used and in
either counting mode the circuits operate synchronously.
The outputs change state synchronous with the LOW-toHIGH transitions on the clock inputs.

Separate Terminal Count Up and Terminal Count Down outputs are provided which are used as the clocks for a subsequent stage without extra logic, thus simplifying multistage
counter designs. Individual preset inputs allow the circuits to
be used as programmable counters. Both the Parallel Load
(pc) and the Master Reset (MR) inputs asynchronously
override the clocks.

Functional Description
The '192 is an asynchronously presettable decade and 4-bit
binary synchronous up/down (reversible) counter. The operating modes of the '192 decade counter and the '193 binary counter are identical, with the only difference being the
count sequences as noted in the State Diagram. Each circuit contains four master/slave flip-flops, with internal gating and steering logic to provide master reset, individual preset, count up, and count down operations.
Each flip-flop contains JK feedback from slave to master
such that a LOW-to-HIGH transition on its T input causes
the slave, and thus the a output to change state. Synchronous switching, as opposed to ripple counting, is achieved
by driving the steering gates of all stages from a common
Count Up line and a common Count Down line, thereby
causing all state changes to be initiated simultaneously. A
LOW-to-HIGH transition on the Count Up input will advance
the count by one; a similar transition on the Count Down
input will decrease the count by one. While counting with
one clock input, the other should be held HIGH. Otherwise,
the circuit will either count by twos or not at all, depending
on the state of the first flip-flop, which cannot toggle as long
as either Clock input is LOW.
The Terminal Count Up (TI:u) and Terminal Count Down
(fOo) outputs are normally HIGH. When a circuit has
reached the maximum count state (9 for the '192, 15 for the
'193), the next HIGH-to-LOW transition of the Count Up
Clock will cause TCu to go LOW. TCu will stay LOW until
CPu goes HIGH again, thus effectively repeating the Count
Up Clock, but delayed by two gate delays. Similarly, the TCo
output will go LOW when the circuit is in the zero state and
the Count Down Clock goes LOW. Since the TC outputs
repeat the clock waveforms, they can be used as the clock
Input signals to the next higher order circuit in a multistage
counter.

TCu = 00-03- CPu
TCo = 00 - 01 - 02 - 03 - CPo
Each circuit has an asynchronous parallel load capability
permitting the counter to be reset. When the Parallel Load
(PL) and the Master Reset (MR) inputs are LOW, information present on the Parallel Data inputs (PO-P3) is loaded
into the counter and appears on the outputs regardless of
the conditions of the clock inputs. A HIGH signal on the
Master Reset input will disable the preset gates, override
both Clock inputs, and latch each a output in the LOW
state. If one of the Clock inputs is LOW during and after a
reset or load operation, the next LOW-to-HIGH transition of
that Clock will be interpreted as a legitimate signal and will
be counted.

54LS 193/DM54LS 193/DM74LS 193
Synchronous 4·Bit Up/Down Binary
Counters with Dual Clock
General Description
This circuit is a synchronous up/down 4-bit binary counter.
Synchronous operation is provided by having all flip-flops
clocked simultaneously, so that the outputs change together when so instructed by the steering logic. This mode of
operation eliminates the output counting spikes normally associated with asynchronous (ripple-clock) counters.
The outputs of the four master-slave flip-flops are triggered
by a low-to-high level transition of either count (clock) input.
The direction of counting is determined by which count Input
is pulsed while the other count input is held high.
The counter is fully programmable; that is, each output may
be preset to either level by entering the desired data at the
inputs while the load input is low. The output will change
Independently of the count pulses. This feature allows the
counters to be used as modulo-N dividers by simply modifying the count length with the preset inputs.
A clear input has been provided which, when taken to a high
level, forces all outputs to the low level; independent of the
count and load inputs. The clear, count, and load inputs are
buffered to lower the drive requirements of clock drivers,
etc., required for long words.

These counters were designed to be cascaded without the
need for external circuitry. Both borrow and carry outputs
are available to cascade both the up and down counting
functions. The borrow output produces a pulse equal in
width to the count down input when the counter underflows.
Similarly, the carry output produces a pulse equal in width to
the count down input when an overflow condition exists.
The counters can then be easily cascaded by feeding the
borrow and carry outputs to the count down and count up
inputs respectively of the succeeding counter.

54LS194A/DM74LS194A 4-Bit
Bidirectional Universal Shift Register
General Description
This bidirectional shift register is designed to incorporate
virtually all of the features a system designer may want in a
shift register; they feature parallel inputs, parallel outputs,
right-shift and left-shift serial inputs, operating-mode-control
inputs, and a direct overriding clear line. The register has
four distinct modes of operation, namely:
Parallel (broadside) load
Shift right (in the direction QA toward QD)
Shift left (in the direction QD toward QA)
Inhibit clock (do nothing)

Serial data for this mode is entered at the shift-right data
input. When SO is low and S1 is high, data shifts left synchronously and new data is entered at the shift-left serial
input.
Clocking of the flip-flop is inhibited when both mode control
inputs are low.

Features

Synchronous parallel loading is accomplished by applying
the four bits of data and taking both mode control inputs, SO
and S 1, high. The data is loaded into the associated flipflops and appear at the outputs after the positive transition
of the clock input. During loading, serial data flow is inhibited.
Shift right is accomplished synchronously with the rising
edge of the clock pulse when SO is high and S1 is low.

• Parallel inputs and outputs
• Four operating modes:
Synchronous parallel load
Right shift
Left shift
Do nothing
• Positive edge-triggered clocking

4-Bit Parallel Access Shift Register
General Description

Features

This 4-bit register features parallel inputs, parallel outputs,
J-K serial inputs, shiftlload control input, and a direct overriding clear. All inputs are buffered to lower the input drive
requirements. The registers have two modes of operation:

•
•
•
•

Parallel (broadside) load

•

Shift (in the direction QA toward Qo)

•
•

Parallel loading is accomplished by applying the four bits of
data and taking the shiftlload control input low. The data is
loaded into the associated flip-flop and appears at the outputs after the positive transition of the clock input. During
loading, serial data flow is inhibited.

Synchronous parallel load
Positive-edge-triggered clocking
Parallel inputs and outputs from each flip-flop
Direct overriding clear
J and K inputs to first stage
Complementary outputs from last stage
For use in high-performance:
accumulatorsl processors
serial-to-parallel, parallel-to-serial converters
Typical clock frequency 39 MHz
Typical power dissipation 70 mW

•
•

Shifting is accomplished synchronously when the shiftlload
control input is high. Serial data for this mode is entered at
the J-K inputs. These inputs permit the first stage to perform
as a J-K, D, or T-type flip-flop as shown in the truth table.

DM74LS196
Presettable Decade Counter
General Description

Features

The 'LS196 decade ripple counter is partitioned into divideby-two and divide-by-five sections which can be combined
to count either in BCD (8421 l sequence or in a bi-quinary
mode producing a 50% duty cycle output. Both circuit types
have a Master Reset (MRl input which overrides all other
inputs and asynchronously forces all outputs LOW. A Parallel Load input (PLl overrides clocked operations and asynchronously loads the data on the Parallel Data inputs (Pn)
into the flip-flops. This preset feature makes the circuits usable as programmable counters. The circuits can also be
used as 4-bit latches, loading data from the Parallel Data
inputs when PL is LOW and storing the data when PL is
HIGH. In the counting modes, state changes are initiated by
the falling edge of the clock.

• High counting rates-typically 60 MHz
• Choice of counting modes-BCD, bi-quinary, binary
• Asynchronous preset and master reset

Functional Description
The '196 and '197 are asynchronous presettable decade
and binary ripple counters. The '196 decade counter is partitioned into divide-by-two and divide-by-five sections while
the '197 is partitioned into divide-by-two and divide-by-eight
sections, with all sections having a separate Clock input. In
the counting modes, state changes are initiated by the
HIGH-to-LOW transition of the clock signals. State changes
of the 0 outputs, however, do not occur simultaneously because of the internal ripple delays. When using external logic to decode the 0 outputs, designers should bear in mind
that the unequal delays can lead to decoding spikes and
thus a decoded signal should not be used as a clock or
strobe. The CPO input serves the 00 flip-flop in both circuit
types while the CP1 input serves the divide-by-five or divideby-eight section. The 00 output is designed and specified to
drive the rated fan-out plus the CP1 input. With the input
frequency connected to CPO and with 00 driving CP1, the
'197 forms a straight forward modul0-16 counter, with 00
the least significant output and 03 the most significant output.

The' 196 decade counter can be connected up to operate in
two different count sequences. With the input frequency
connected to CPO and with 00 driving CP1, the circuit
counts in the BCD (8421) sequence. With the input frequency connected to CP1 and 03 driving CPO, 00 becomes the
low frequency output and has a 50% duty cycle waveform.
Note that the maximum counting rate is reduced in the latter
(bi-quinary) configuration because of the interstage gating
delay within the divide-by-five section.
The '196 and '197 have an asynchronous active LOW Master Reset input (MR) which overrides all other inputs and
forces all outputs LOW. The counters are also asynchronously presettable. A LOW on the Parallel Load input (PL)
overrides the clock inputs and loads the data from Parallel
Data (PO-P3) inputs into the flip-flops. While PL is LOW, the
counters act as transparent latches and any change in the
Pn inputs will be reflected in the outputs. In order for the
intended parallel data to be entered and stored, the recommended setup and hold times with respect to the rising
edge of PL should be observed.

8. Duty cycle is defined as TwIT x 100 in percentage, if it
goes above 50% the output pulse width will become
shorter. If the duty cycle varies between low and high
values, this causes output pulse width to vary, or jitter (a
function of the REXT only). To reduce jitter, REXT should
be as large as possible, for example, with REXT = 100k
jitter is not appreciable until the duty cycle approaches
90%.

Operating Rules (Continued)
9. Under any operating condition Cx and Rx must be kept
as close to the one-shot device pins as possible to minimize stray capacitance, to reduce noise pick-up, and to
reduce I-R and Ldi/dt voltage developed along their
connecting paths. If the lead length from Cx to pins (6)
and (7) or pins (14) and (15) is greater than 3 cm, for
example, the output pulse width might be quite different
from values predicted from the appropriate equations. A
non-inductive and low capacitive path is necessary to
ensure complete discharge of Cx in each cycle of its
operation so that the output pulse width will be accurate.
10. Although the 'LS221's pin-out is identical to the 'LS123
it should be remembered that they are not functionally
identical. The 'LS123 is a retriggerable device such that
the output is dependent upon the input transitions when

its output "0" is at the "High" state. Furthermore, it is
recommended for the 'LS123 to externally ground the
CEXT pin for improved system performance. However,
this pin on the 'LS221 Is not an internal connection to
the device ground. Hence, if substitution of an 'LS221
onto an 'LS123 design layout where the CEXT pin is
wired to the ground, the device will not function.
11. Vee and ground wiring should conform to good high-frequency standards and practices so that switching transients on the Vee and ground return leads do not cause
interaction between one-shots. A 0.01 /-tF to 0.10 /-tF
bypass capacitor (disk ceramic or monolithic type) from
Vee to ground is necessary on each device. Furthermore, the bypass capacitor should be located as close
to the Vee-pin as space permits.
For further detailed device characteristics and output performance,
please refer to the NSC one-shot application note AN-366.

Octal TRI-STATE® Buffers/Line Drivers/Line Receivers
General Description
These buffers/line drivers are designed to improve both the
performance and PC board density of TRI-STATE buffers/
drivers employed as memory-address drivers, clock drivers,
and bus-oriented transmitters/ receivers. Featuring 400 mV
of hysteresis at each low current PNP data line input, they
provide improved noise rejection and high fanout outputs
and can be used to drive terminated lines down to 1330.

54LS245/DM54LS245/DM74LS245
TRI-STATE® Octal Bus Transceiver
General Description
• PNP inputs reduce DC loading on bus lines

These octal bus transceivers are designed for asynchronous two-way communication between data buses. The
control function implementation minimizes external timing
requirements.
The device allows data transmission from the A bus to the B
bus or from the B bus to the A bus depending upon the logiC
level at the direction control (DIR) input. The enable input
(G) can be used to disable the device so that the buses are
effectively isolated.

II Hysteresis at bus inputs improve noise margins

• Typical propagation delay times, port-to-port 6 ns
• Typical enable/disable times 17 ns
• IOL (sink current)

Note 1: IIDRIil:) Is wired-AND logic serving as blanking Input (81) and/or ripple-blanking oulput (FiiID). The blanking out (1i1) must be open or held at a HIGH level
when output functions 0 through 15 are desired. X = input may be HIGH or LOW.
Note 2: When a LOW level Is applied to the blanking Input (forced condition) all segment oulputs go to a LOW level, regardless of the state of any other Input
condHlon.

TRI-STATE® Data Selectors/Multiplexers
General Description

Features

These data selectors/multiplexers contain full on-chip binary decoding to select one-of-eight data sources. and feature
a strobe-controlled TRI-STATE output. The strobe must be
at a low logic level to enable these devices. The TRI-STATE
outputs permit direct connection to a common bus. When
the strobe input is high. both outputs are in a high-impedance state in which both the upper and lower transistors of
each totem-pole output are off. and the output neither drives
nor loads the bus significantly. When the strobe is low. the
outputs are activated and operate as standard TTL totempole outputs.

•
•
•
•
•
•

To minimize the possibility that two outputs will attempt to
take a common bus to opposite logic levels. the output control circuitry is designed so that the average output disable
time is shorter than the average output enable time.

54LS253/DM54LS253/DM74LS253
TRI-STATE® Data Selectors/Multiplexers
General Description

Features

Each of these Schottky-clamped data selectors/multiplexers contains inverters and drivers to supply fully complementary, on-Chip, binary decoding data selection to the
AND-OR gates. Separate output control inputs are provided
for each of the two four-line sections.
The TRI-STATE outputs can interface directly with data
lines of bus-organized systems. With all but one of the common outputs disabled (at a high impedance state), the low
impedance of the single enabled output will drive the bus
line to a high or low logic level.

54LS256/DM74LS256
Dual 4·Bit Addressable Latch
General Description
The 'LS256 is a dual 4-bit addressable latch with common
control inputs; these include two Address inputs (AO, A 1),
an active LOW enable input (E) and an active LOW Clear
input (CL). Each latch has a Data input (D) and four outputs
(00-03).

could impose a transient wrong address. Therefore, this
should be done only while in the memory mode (E = CL =
HIGH).

When the Enable (E) is HIGH and the Clear input (CL) is
LOW, all outputs (00-03) are LOW. Dual 4-channel demultiplexing occurs when the CL and E are both LOW. When
CL is HIGH and E is LOW, the selected output (00-03),
determined by the Address inputs, follows D. When the E
goes HIGH, the contents of the latch are stored. When operating in the addressable latch mode (E = LOW, CL =
HIGH), changing more than one bit of the Address (AO, A 1)

TRI-STATE® Quad 2-Data Selectors/Multiplexers
General Description

Features

These Schottky-clamped high-performance multiplexers
feature TAl-STATE outputs that can interface directly with
data lines of bus-organized systems. With all but one of the
common outputs disabled (at a high impedance state), the
low impedance of the single enabled output will drive the
bus line to a high or low logic level. To minimize the possibility that two outputs will attempt to take a common bus to
OPPOSite logic levels, the output enable circuitry is designed
such that the output disable times are shorter than the output enable times.
This TAl-STATE output feature means that n-bit (paralleled)
data selectors with up to 258 sources can be implemented
for data buses. It also permits the use of standard TTL registers for data retention throughout the system.

• TAl-STATE versions LS157 and LS158 with same pinouts
• Schottky-clamped for Significant improvement in A-C
performance
• Provides bus interface from multiple sources in highperformance systems
• Average propagation delay from data input 12 ns
• Typical power dissipation
LS257B 50 mW
LS258B 35 mW
• Altemate military/aerospace devices (54LS257A1
54LS258A) are available. Contact a National Semiconductor Sales Office/Distributor for specifications.

54LS259/DM74LS259 a-Bit Addressable Latches
General Description

Features

These 8-bit addressable latches are designed for general
purpose storage applications in digital systems. Specific
uses include working registers, serial-holding registers, and
active-high decoders or demultiplexers. They are multifunctional devices capable of storing single-line data in eight
addressable latches, and being a 1-of-8 decoder or demultiplexer with active-high outputs.

• 8-Bit parallel-out storage register performs serial-to-parallel conversion with storage
• Asynchronous parallel clear
• Active high decoder
• Enable/disable input simplifies expansion
• Direct replacement for Fairchild 9334
• Expandable for N-bit applications
• Four distinct functional modes
• Typical propagation delay times:
Enable-to-output 18 ns
Data-to-output 16 ns
Address-to-output 21 ns
Clear-to-output 17 ns

Four distinct modes of operation are selectable by controlling the clear and enable inputs as enumerated in the function table. In the addressable-latch mode, data at the datain terminal is written into the addressed latch. The addressed latch will follow the data input with all unaddressed
latches remaining in their previous states. In the memory
mode, all latches remain in their previous states and are
unaffected by the data or address inputs. To eliminate the
possibility of entering erroneous data in the latches, the enable should be held high (inactive) while the address lines
are changing. In the 1-of-8 decoding or demultiplexing
mode, the addressed output will follow the level of the D
input with all other outputs low. In the clear mode, all outputs are low and unaffected by the address and data inputs.

54LS279/DM54LS279/DM74LS279
Quad S-R Latches
General Description
The 'LS279 consists of four individual and independent SetReset Latches with active low inputs. Two of the four latches have an additonal S input ANDed with the primary S
input. A Iowan any S input while the R input is high will be
stored in the latch and appear on the corresponding a output as a high. A Iowan the R input while the S input is high
will clear the output to a low. Simultaneous transistion of
the Rand S inputs from low to high will cause the output

a

a

to be indeterminate. Both inputs are voltage level triggered
and are not affected by transition time of the input data.

Features
• Alternate military/aerospace device (54LS279) is available. Contact a National Semiconductor Sales Office/
Distributor for specifications.

54LS283/DM54LS283/DM74LS283
4·Bit Binary Adders with Fast Carry
General Description

Features

These full adders perform the addition of two 4-bit binary
numbers. The sum (I) outputs are provided for each bit and
the resultant carry (C4) is obtained from the fourth bit.
These adders feature full internal look ahead across all four
bits. This provides the system designer with partial lookahead performance at the economy and reduced package
count of a ripple-carry implementation.

• Full-carry look-ahead across the four bits
• Systems achieve partial look-ahead performance with
the economy of ripple carry
• Typical add times
Two B-bit words 25 ns
Two 16-bit words 45 ns
• Typical power dissipation per 4-blt adder 95 mW
• Alternate Military/Aerospace device (54LS283) is available. Contact a National Semiconductor Sales Office/
Distributor for specifications.

The adder logic, including the carry, is implemented in its
true form meaning that the end-around carry can be accomplished without the need for logic or level inversion.

II?A National
~ Semiconductor
DM74LS290 4-Bit Decade Counter
General Description
The 'LS290 counter is electrically and functionally identical
to the 'LS90. Only the arrangement of the terminals has
been changed for the 'LS290.
Each of these monolithic counters contains four masterslave flip-flops and additional gating to provide a divide-bytwo counter and a three-stage binary counter for which the
count cycle length is divide-by-five.
This counter has a gated zero reset and gated set-to-nine
inputs for use in BCD nine's complement applications.
To use the maximum count length (decade) of this counter,
the B input is connected to the QA output. The input count
pulses are applied to input A and the outputs are as de-

scribed in the appropriate function table. A symmetrical divide-by-ten count can be obtained from the 'LS290 counter
by connecting the Qo output to the A input and applying the
input count to the B input which gives a divide-by-ten square
wave at output QA.

Features
• GND and Vee on Corner Pins
(Pins 7 and 14 respectively)
• Typical power disSipation 45 mW
• Count frequency 42 MHz

54LS295A/DM74LS295A
4-Bit Shift Register with TRI-STATE® Outputs
General Description

Features

The 'LS295A is a 4-bit shift register with serial and parallel
synchronous operating modes, and independent TRISTATE output buffers. The Parallel Enable input (PE) controls the shift-right or parallel load operation. All data transfers and shifting occur synchronous with the HIGH-to-LOW
clock transition.
The TRI-STATE output buffers are controlled by an active
HIGH Output Enable input (OE). Disabling the output buffers
does not affect the shifting or loading of input data, but it
does inhibit serial expansion. The device is fabricated with
the Schottky barrier diode process for high speed.

Functional Description

I\)

CD

This device is a 4-bit shift register with serial and parallel
synchronous operating modes. It has a Serial Data (Os) and
four Parallel Data (PO-P3) inputs and four parallel TRISTATE output buffers (00-03). When the Parallel Enable
(PE) input is HIGH, data is transferred from the Parallel Data
inputs (PO-P3) into the register synchronous with the HIGHto-LOW transition of the Clock (CP). When the PE is LOW, a
HIGH-to-LOW transition on the clock transfers the serial
data on the Os input to the register 00, and shifts data from
00 to 01, 01 to 02 and 02 to 03. The input data and
parallel enable are fully edge-triggered and must be stable
only one setup time before the HIGH-to-LOW clock transition.

The TRI-STATE output buffers are controlled by an active
HIGH Output Enable input (OE). When the OE is HIGH, the
four register outputs appear at the 00-03 outputs. When
OE is LOW, the outputs are forced to a high impedance
OFF state. The TRI-STATE output buffers are completely
independent of the register operation, i.e., the input transitions on the OE input do not affect the serial or parallel
data transfers of the register. If the outputs are tied together, all but one device must be in the high impedance state to
avoid high currents that would exceed the maximum ratings.
Designers should ensure that Output Enable Signals to TRISTATE devices whose outputs are tied together are deSigned so there is no overlap.

54LS322/DM74LS322
8-Bit Serial/Parallel Register with Sign Extend
General Description
The 'LS322 is an 8-bit shift register with provision for either
serial or parallel loading and with TRI-STATE® parallel outputs plus a bi-state serial output. Parallel data inputs and
parallel outputs are multiplexed to minimize pin count. State
changes are initiated by the rising edge of the clock. Four
synchronous modes of operation are possible: hold (store),

shift right with serial entry, shift right with sign extend and
parallel load. An asynchronous Master Reset (MR) input
overrides clocked operation and clears the register. The
'322 is specifically designed for operation with the '384 Multiplier and provides the sign extend function required for the
'384.

Functional Description
The LS322 contains eight D-type edge triggered flip-flops
and the interstage gating required to perform right shift and
the intrastage gating necessary for hold and synchronous
parallel load operations. A LOW signal on RE enables shifting or parallel loading, while a HIGH signal enables the hold
mode. A HIGH signal on SIP enables shift right, while a
LOW signal disables the TRI-STATE output buffers and enabies parallel loading. In the shift right mode a HIGH signal

on SE enables serial entry from either DO or D1, as determined by the S input. A LOW signal on SE enables shift right
but 07 reloads its contents, thus performing the sign extend
function required for the '384 Twos Complement Multiplier.
A HIGH signal on OE disables the TRI-STATE output buffers, regardless of the other control inputs. In this condition
the shifting and loading operations can still be performed.

54LS323/DM74LS323
8-Bit Universal Shift/Storage Register
with Synchronous Reset and Common I/O Pins
General Description

Features

The 'LS323 is an 8-bit universal shift/storage register with
TRI-STATE® outputs. Its function is similar to the 'LS299
with the exception of Synchronous Reset. Parallel load inputs and flip-flop outputs are multiplexed to minimize pin
count. Separate inputs and outputs are provided for flipflops 00 and 07 to allow easy cascading. Four operation
modes are possible: hold (store), shift left, shift right, and
parallel load. All modes are activated on the LOW-to-HIGH
transition of the Clock.

• Common I/O for reduced pin count
• Four operation modes: shift left, shift right, parallel load
and store
• Separate continuous inputs and outputs from 00 and
07 allow easy cascading
• Fully synchronous reset
• TRI-STATE outputs for bus oriented applications

Functional Description
The 'LS323 contains eight edge-triggered Ootype flip-flops
and the interstage logic necessary to perform synchronous
reset, shift left, shift right, parallel load and hold operations.
The type of operation is determined by SO and 51 as shown
in the Mode Select Table. All flip-flop outputs are brought
out through TRI-STATE buffers to separate I/O pins that
also serve as data inputs in the parallel load mode. QO and
Q7 are also brought out on other pins for expansion in serial
shifting of longer words.
A LOW signal on SR overrides the Select inputs and allows
the flip-flops to be reset by the next rising edge of CPo All
other state changes are also initiated by the LOW-to-HIGH
CP transition. Inputs can change when the clock is in either
state provided only that the recommended setup and hold
times, relative to the rising edge of CP, are observed.
A HIGH signal on either OEI or OE2 disables the TRISTATE buffers and puts the 1/0 pins in the high impedance
state. In this condition the shift, load, hold and reset operations can still occur. The TRI-STATE buffers are also disabled by HIGH signals on both SO and 51 in preparation for
a parallel load operation.

Functional Description
The 'LS353 contains two identical4-input multiplexers with
TRI-STATE outputs. They select two bits from four sources
selected by common Select inputs (SO, 51). The 4-input
multiplexers have individual Output Enable (OEa>, OEb) inputs which when HIGH, force the outputs to a high impedance (high Z) state. The logic equations for the outputs are
shown below:

If the outputs of TRI-STATE devices are tied together, all
but one device must be in the high impedance state to avoid
high currents that would exceed the maximum ratings. Designers should ensure that Output Enable signals to TRISTATE devices whose outputs are tied together are designed so that there is no overlap.

54LS365A/DM54LS365A/DM74LS365A
Hex TRI-STATE® Buffers
General Description
This device contains six independent gates each of which
performs a non-inverting buffer function. The outputs have
the TRI-STATE feature. When enabled. the outputs exhibit
the low impedance characteristics of a standard LS output
with additional drive capability to permit the driving of bus
lines without external resistors. When disabled. both the
output transistors are turned off presenting a high-impedance state to the bus line. Thus the output will act neither as
a significant load nor as a driver. To minimize the possibility

that two outputs will attempt to take a common bus to opposite logic levels. the disable time is shorter than the enable
time of the outputs.

• Alternate Military/Aerospace device (54LS365A) is

54LS366A/DM74LS366A
Hex TRI-STATE® Inverting Buffers
General Description
This device contains six independent gates each of which
performs an Inverting buffer function. The outputs have the
TRI-STATE feature. When enabled, the outputs exhibit the
low impedance characteristics of a standard LS output with
additional drive capability to permit the driving of bus lines
without external reSistors. When disabled, both the output

transistors are turned off presenting a high-impedance state
to the bus line. Thus the output will act neither as a significant load nor as a driver. To minimize the possibility that two
outputs will attempt to take a common bus to opposite logic
levels, the disable time is shorter than the enable time of the
outputs.

TRI-STATE® Octal D-Type Transparent
Latches and Edge-Triggered Flip-Flops
General Description

Features

These a-bit registers feature totem-pole TRI-STATE outputs
designed specifically for driving highly-capacitive or relatively low-impedance loads. The high-impedance state and increased high-logic level drive provide these registers with
the capability of being connected directly to and driving the
bus lines in a bus-organized system without need for interface or pull-up components. They are particularly attractive
for implementing buffer registers, I/O ports, bidirectional
bus drivers, and working registers.
(Continued)

II Choice of a latches or a D-type flip-flops in a single

package
• TRI-STATE bus-driving outputs
iii Full parallel-access for loading
• Buffered control inputs
• P-N-P inputs reduce D-C loading on data lines

General Description

(Continued)
The eight latches of the DM54174LS373 are transparent 0type latches meaning that while the enable (G) is high the
outputs will follow the data (D) inputs. When the enable is
taken low the output will be latched at the level of the data
that was set up.

A buffered output control input can be used to place the
eight outputs in either a normal logic state (high or low logic
levels) or a high-impedance state. In the high-impedance
state the outputs neither load nor drive the bus lines significantly.
The output control does not affect the internal operation of
the latches or flip-flops. That is, the old data can be retained
or new data can be entered even while the outputs are off.

a

The eight flip-flops of the DM54174LS374 are edge-triggered D-type flip flops. On the positive transition of the
clock, the a outputs will be set to the logic states that were
set up at the 0 inputs.

54LS375/DM74LS375
4-Bit Latch
General Description

The 'LS375 is a 4-bit D-type latch for use as temporary storage for binary information between processing units and input/output or indicator units. When its Enable (E) input is
HIGH, a latch is transparent, i.e., the Q output will follow the

D input each time it changes. When E is LOW a latch stores
the last valid data present on the D input preceding the
HIGH-to-LOW transition of E. The 'LS375 is functionally
identical to the 'LS75 except for the comer power pins.

DM54LS380/74LS380
Multifunction Octal Register
General Description
The 'LS380 is an 8-bit synchronous register with parallel
load, load complement, preset, clear, and hold capacity.
Four control inputs (LD, POL, CLR, PRj provide one of four
operations which occur synchronously on the rising edge of
the clock (CK). The LS380 combines the features of the
LS374, LS377, LS273 and LS534 into a single 300 mil wide
package.
The LOAD operation loads the inputs (Dr Do) into the output register (OrOo), when POL is HIGH, or loads the compliment of the inputs when POL is LOW. The CLEAR operation resets the output register to all LOWs. The PRESET
operation presets the output register to all HIGHs. The
HOLD operation holds the previous value regardless of
clock transitions. CLEAR overrides PRESET, PRESET overrides LOAD, and LOAD overrides HOLD.

Connection Diagram

The output register (07-00) is enabled when OE is LOW,
and disabled (HI-Z) when OE is HIGH. The output drivers
will sink the 24 mA required for many bus interface standards.

Features/Benefits
• Octal Register for general purposes interfacing
applications
• 8 bits match byte boundaries
• Bus-structured pinout
• 24-pin SKINNYDIP saves space
• TRI-STATEIID outputs
• Low current PNP inputs reduce loading

DM74LS390 Dual4-Bit Decade Counter
General Description

Features

Each of these monolithic circuits contains eight masterslave flip-flops and additional gating to implement two individual four-bit counters in a single package. The 'LS390 incorporates dual divide-by-two and divide-by-five counters,
which can be used to implement cycle lengths equal to any
whole andlor cumulative multiples of 2 andlor 5 up to divide-by-100. When connected as a bi-quinary counter, the
separate divide-by-two circuit can be used to provide symmetry (a square wave) at the final output stage. The 'LS390
has parallel outputs from each counter stage so that any

54LS395/DM74LS395
4-Bit Shift Register with TRI-STATE® Outputs
General Description

Features

The LS395 is a 4-bit shift register with TRI-STATE outputs
and can operate in either a synchronous parallel load or a
serial shift-right mode. as determined by the Select input An
asynchronous active LOW Master Reset (MR) input overrides the synchronous operations and clears the register_
An active LOW Output Enable (OE) input controls the TRISTATE output buffers. but does not interfere with the other
operations_ The fourth stage also has a conventional output
for linking purposes in multi-stage serial operations_

Functional Description
served. When the S input is LOW, a CP HIGH-LOW transition transfers data in 00 to ai, 01 to 02, and 02 to 03. A
left-shift is accomplished by connecting the outputs back to
the Pn inputs, but offset one place to the left, i.e., 03 to P2,
02 to PI, and 01 to PO, with P3 acting as the linking input
from another package.
When the OE input is HIGH, the output buffers are disabled
and the 00-03 outputs are in a high impedance condition.
The shifting, parallel loading or resetting operations can still
be accomplished, however.

The LS395 contains four D-type edge-triggered flip-flops
and auxiliary gating to select a D input either from a Parallel
(P n) input or from the preceding stage. When the Select
input is HIGH, the Pn inputs are enabled. A LOW signal in
the S input enables the serial inputs for shift-right operations, as indicated in the Truth Table.
State changes are initiated by HIGH-to-LOW transitions on
the Clock Pulse (CP) input. Signals on the Pn, DS and S
inputs can change when the Clock is in either state, provided that the recommended setup and hold times are ob-

DM54LS461/DM74LS461 Octal Counter
General Description
The LS461 is an 8-bit synchronous counter with parallel
load, clear, and hold capability. Two function select inputs
(10, 11) provide one of four operations which occur synchronously on the rising edge of the clock (CK).
The LOAD operation loads the inputs (07-00) into the output register (07-00). The CLEAR operation resets the output register to all LOWs. The HOLD operation holds the
previous value regardless of clock transitions. The INCREMENT operation adds one to the output register when the
carry-in input is TRUE (ci = LOW), otherwise the operation
is a HOLD. The carry-out (CO) is TRUE (CO = LOW) when
the output register (OrOo) is all HIGHs, otherwise FALSE
(CO = HIGH).

Two or more LS461 octal counters may be cascaded to
provide larger counters. The operation codes were chosen
such that when 11 is HIGH, 10 may be used to select between LOAD and INCREMENT as in a program counter
(JUMPIINCREMENT).

Features/Benefits
• Octal counter for microprogram-counter, DMA controller
and general purpose counting applications
• 8 bits match byte boundaries
• Bus-structured pinout
• 24-pin Skinny Dip saves space
• TRI-STATE@) outputs drive bus lines
• Low current PNP inputs reduce loading
• Expandable in 8-bit increments

The output register (07-00) is enabled when OE is LOW,
and disabled (HI-Z) when OE is HIGH. The output drivers
will sink the 24 mA required for many bus interface standards.

DM54LS461A/DM74LS461 A Octal Counter
General Description
The LS461A is an 8-bit synchronous counter with parallel
load, clear and hold capability. Two function select inputs
(10, 11) provide one of four operations which occur synchronously on the rising edge of the (CK).

Two or more LS461A octal counters may be cascaded to
provide larger counters. The operation codes were chosen
such that when 11 is HIGH 10 may be used to select between LOAD and INCREMENT as in a program counter
(JUMPIINCREMENn.

The LOAD operation loads the inputs (07-00) into the output register (Q7-QO). The CLEAR operation resets the output register to all LOWs. The HOLD operation holds the
previous value regardless of the clock transitions. The INCREMENT operation adds one to the output register when
the carry-in input is TRUE (Ci = LOW), otherwise the operation is a HOLD. The carry-out (CO) is True (CO = LOW)
when the output register (Q7-QO) is all HIGHs, otherwise
FALSE (CO = HIGH).
The output register (Q7-QO) is enabled when ()E is LOW,
and disabled (HI-Z) when ()E is HIGH. The output drivers
will sink 24 mA required for many bus interface standards.

Features
• Octal counter for microprogram-counter, DMA controller
for general purpose counting applications
• 8 bits match byte boundaries
• Low current PNP inputs reduce loading
• Bus-structured pinout
• TRI-STATEIIl> outputs drive bus lines
• 24-pin SKINNYDIP saves space
• Expadable in 8-bit increments

1: Absolute maximum ratings are those values beyond which the device may be permanently damaged. They do not mean that the device may be oparated at

these values.
Note 2: These are absolute voltages with respect to the ground pin on the device and include all overshoots due to system and/or tester noise. Do not attempt to
test these values without suiteble equipment.
Nota 3: 110 leakage as the worst case of 10ZX or IIX, e.g., I,L and 10ZL.
Note 4: During los measurement, only one output at a time should be grounded. Pennanent damage otherwise may result.

DM7 4LS465/DM74LS466/DM7 4LS467/DM7 4LS468
TRI-STATE® Octal Buffers
General Description
These devices provide eight, two-input buffers in each package. All employ the newest low-power-Schottky TTL technology. One of the two inputs to each buffer is used as a
control line to gate the output into the high-impedance
state, while the other input passes the data through the buffer. The 'LS465 and 'LS467 present true data at the outputs,
while the 'LS466 and 'LS468 are inverting. On the 'LS465
and 'LS466 versions, all eight TRI-STATE enable lines are
common, with access through a 2-input NOR gate. On the
'LS467 and 'LS468 versions, four buffers are enabled from
one common line, and the other four buffers are enabled
from another common line. In all cases the outputs are
placed in the TRI-STATE condition by applying a high logic
level to the enable pins. These devices represent octal, low
power-Schottky versions of the very popular DM54174365,
366, 367, and 368 (DM8095, 96, 97, and 98) TRI-STATE
hex buffers.

Features
• Octal versions of popular DM74365, 366, 367, and 368
(DM8095, 96, 97 and 98)
• Typical power dissipation
DM74LS465, 467 80 mW
DM74LS466, 468 65 mW
• Typical propagation delay
DM74LS465,467 15 ns
DM74LS466,468 10 ns
• Low power-Schottky, TRI-STATE technology

DM54lS469/DM74LS469 8-Bit Up/Down Counter
General Description
The 'LS469 is an a-bit synchronous up/down counter with
parallel load and hold capability. Three function-select inputs (LD, UD, CBI) provide one of four operations which
occur synchronously on the rising edge of the clock (CK).
The LOAD operation loads the inputs (07-00) into the output register (07-00). The HOLD operation holds the previous value regardless of clock transitions. The INCREMENT
operation adds one to the output register when the carry-in
input is TRUE (CBI = LOW), otherwise the operation is a
HOLD. The carry-out (CBO) is TRUE (CBO=LOW) when
the output register (OrOo) is all HIGHs, otherwise FALSE
(CBO=HIGH). The DECREMENT operation subtracts one
from the output register when the borrow-in input is TRUE
(CBI = LOW), otherwise the operation is a HOLD. The borrow-out (CBO) is TRUE (CBO= LOW) when the output register (07-00) is all LOWs, otherwise FALSE (CBO=HIGH).

The output register (07-00) is enabled when OE is LOW,
and disabled (HI-Z) when OE is HIGH. The output drivers
will sink the 24 mA required for many bus-interface standards. Two or more 'LS469 octal up/down counters may be
cascaded to provide larger counters.

DM54LS469A/DM74LS469A 8-Bit Up/Down Counter
General Description
The 'LS469A is an a-bit synchronous up/down counter with
parallel load and hold capability. Three function-select inputs (LD, UD, CBI) provide one of four operations which
occur synchronously on the rising edge of the clock (CK).
The LOAD operation loads the inputs (D7-DO) into the output register (07-00). The HOLD operation holds the previous value regardless of clock transitions. The INCREMENT
operation adds one to the output register when the carry-in
input is TRUE (CBI = LOW), otherwise the operation is a
HOLD. The carry-out (CBO) is True (CBO = LOW) when
the output register (07-00) is all HIGHs, otherwise FALSE
(CBO = HIGH). The DECREMENT operation subtracts one
from the output register when the borrow-in input is TRUE
(CBI = LOW), otherwise the operation is a HOLD. The borrow-out (CBO) is true (CBO = LOW) when the output register (07-00) is all LOWs, otherwise FALSE (CBO = HIGH).

The output register (07-00) is enabled when OE is LOW,
and disabled (HI-Z) when OE is HIGH. The output drivers
will sink the 24 mA required for many bus-interface standards. Two or more 'LS469A octal up/down counters may
be cascaded to provide larger counters.

Features
• Octal Register for general purpose interfacing
applications
• a bits match byte boundaries
• Low current PNP inputs reduce loading
• Bus-structured pinout
• TRI-STATEIlil outputs
• 24-pin SKINNYDIP saves space

Note 1: Absolute maximum ratings are those values beyond which the device may be permanently damaged. They do not mean that the device maybe operated at
these values.
Note 2: These are absolute voltages with respect to the ground pin on the device and include all overshoots due to system andlor tester noise. Do not attempt to
test these values without suHable equipment.
Note 3: 1/0 leakage as the worst case 01 10ZX or IIX. e.g .• IlL and 10ZL
Note 4: During los measurement. only one output at a time should be grounded. Permanent damage otherwise may result.

General Description

Features/Benefits

The ten-bit counter can count up, count down, set, and load
2 LSB's, 2 MSB's and 6 middle bits high or low as a group.
All operations are synchronous with the clock. SET overrides LOAD, COUNT and HOLD. LOAD overrides COUNT.
COUNT is conditional on CIN, otherwise it holds.
All outputs are enabled when OE is low, otherwise HIGH-Z.
The 24 mA IOL outputs are suitable for driving RAM/PROM
address lines in video graphics systems.

Note 1: Absolute maximum ratings are those values beyond which the device may be permanently damaged. They do not mean that the device may be operated at
these values.
Note 2: These are absolute voltages with respect to the ground pin on the device and include all overshoots due to system andlor tester noise. Do not attempt to
test these values without suitable equipment.
Note 3: 1/0 leakage as the worst case of 10ZX or IIX, e.g., IlL and 10Zl.
Note 4: During los measurement, only one output at a time should be grounded. Permanent damage otherwise may result.

DM54LS498/DM74LS498 Octal Shift Register
General Description
The LS498 is an 8-bit synchronous shift register with parallel
load and hold capability. Two function select inputs (la, 11)
provide one of four operations which occur synchronously
on the rising edge of the clock (CK).
The LOAD operation loads the input (D7-DO) into the output register (07-00)' The HOLD operation holds the previous value regardless of clock transitions. The SHIFT LEFT
operation shifts the output register, 0, one bit to the left; 00
is replaced by L1RO. RILO outputs 07.
The SHIFT RIGHT operation shifts the output register, 0,
one bit to the right; 07 is replaced by RILO. L1RO outputs
00·
The output register (07-00)-is enabled when OE is LOW,
and disabled (HI-Z) when OE is HIGH. The output drivers
will sink the 24 mA required for many bus interface standards.

Connection Diagram

Two or more LS498 octal shift registers may be cascaded to
provide larger shift registers as shown in the application
section.

Features/Benefits
• Octal shift register for serial to parallel and parallel to
serial applications
• 8 bits match byte boundaries
• Bus-structured pinout
• 24-pin SKINNYDIP saves space
• TRI-STATE® outputs drive bus lines
• Low current PNP inputs reduce loading
• Expandable in 8-bit increments

54LS502/DM74LS502
8-Bit Successive Approximation Register
General Description
The LS502 is an B-bit register with the interstage logic necessary to perform serial-to-parallel conversion and provide
an active LOW Conversion Complete (CC) signal coincident
with storage of the eighth bit. An active LOW Start (5) input
performs synchronous initialization which forces 07 LOW
and all other outputs HIGH. Subsequent clocks shift this 07
LOW signal downstream which simultaneously backfills the
register such that the first serial data (D input) bit is stored in
07, the second bit in 06, the third in 05, etc. The serial
input data is also synchronized by an auxiliary flip-flop and
brought out on 00.

Connection Diagram

Designed primarily for use in the successive approximation
technique for analog-to-digital conversion, the LS502 can
also be used as a serial-to-parallel converter ring counter
and as the storage and control element in recursive digital
routines.

Features
• Low power Schottky version of 2502
• Storage and control for successive approximation A to
D conversion
• Performs serial-to-parallel conversion

Functional Description
The register stages are composed of transparent RS latches arranged in master/slave pairs. The master and slave
latches are enabled separately by non-overlapping complementary signals <1>1 and <1>2 derived internally from the CP
input. Master latches are enabled when CP is LOW and
slave latches are enabled when CP is HIGH. Information is
transferred from master to slave, and thus to the outputs, by
the LOW-to-HIGH transition of CPo

cc po- CQNVERSION

Q7

Q6 Q5 Q4 Q3 Q2 Ql QO

COMPLrn

Yt-HH-+-+-+-+---

Initializing the register requires a LOW signal on S while
exercising CPo With Sand CP LOW, all master latches are
SET (0 side HIGH). A LOW-to-HIGH CP transition, with S
remaining LOW, then forces the slave latches to the condition wherein 07 is LOW and all other register outputs, including CC, are HIGH. This condition will prevail as long as
S remains LOW, regardless of subsequent CP rising edge.
To start the conversion process, S must return to the HIGH
state. On the next CP rising edge, the information stored in
the serial data input latch is transferred to 00 and 07, while
Q6 is forced to the LOW state. On the rising edge of the
next seven clocks, this LOW signal is shifted downstream,
one bit at a time, while the serial data enters the register
position one bit behind .this LOW Signal, as shown in the
Truth Table. Note that after a serial data bit appears at a
particular output, that register position undergoes no further
changes. After the shifted LOW signal reaches CC, the register is locked up and no further changes can occur until the
register is initialized for the next conversion process.

FIGUREa.

r.s.

Figure a shows a simplified hook-up of a LS502, a D/ A converter and a comparator arranged to convert an analog input voltage into an 8-bit binary number by the successive
approximation technique. Figure b is an idealized graph
showing the various values that the D/A converter output
voltage can assume in the course of the conversion. The
vertical axis is calibrated in fractions of the full-scale output
capability of the D/A converter and the horizontal axis represents the successive states of the Truth Table. At time t1,
Q7 is LOW and 06-QO are HIGH, causing the D/A output
to be one-half of full scale. If the analog input voltage is
greater than this voltage the comparator output (hence the
D input of the LS502) will be LOW, and at times t2 the D/ A
output will rise to three-fourths of full scale because Q7 will
remain LOW and contribute 50% while Q6 is forced LOW
and contributes another 25%. On the other hand, if the analog input voltage is less than one-half of full scale, the comparator output will be HIGH and 07 will go HIGH at 12. Q6
will still be forced LOW at t2, and the D/ A output will decrease to 25% of full scale. Thus with each successive
clock, the D/A output will change by smaller increments.
When the conversion is completed at t9, the binary number
represented by the register outputs will be the numerator of
the fraction n/256, representing the analog input voltage as
a fraction of the full scale output D/ A converter.

54LS503/DM74LS503
8-Bit Successive Approximation
Register (with Expansion Control)
General Description

Features

The 'LS503 register is basically the same as the 'LS502
except that it has an active LOW Enable (E) input that is
used in cascading two or more packages for longer word
lengths. A HIGH signal on E, after a START operation,
forces 07 HIGH and prevents the device from accepting
serial data. With the E input of an 'LS503 connected to the
CC output of a preceding (more significant) device, the
'LS503 will be inhibited until the preceding device is filled,
causing its CC output to go LOW. This LOW signal then
enables the 'LS503 to accept the serial data on subsequent
clocks. For a description of the starting, shifting and conversion operations, please see the 'LS502 data sheet.

• Performs serial-to-parallel conversion
• Expansion control for longer words
• Storage and control for successive approximation

Functional Description

Truth Table

The '534 consists of eight edge-triggered flip-flops with individual D-type inputs and TRI-STATE true outputs. The buffered clock and buffered Output Enable are common to all
flip-flops. The eight flip-flops will store the state of their individual D inputs that meet the setup and hold times requirements on the LOW-to-HIGH Clock (CP) transistion. With the
Output Enable (OE) LOW, the contents of the eight flip-flops
are available at the outputs. When the OE is HIGH, the outputs go to the high impedance state. Operation of the OE
input does not affect the state of the flip-flops.

Functional Description
puts a setup time preceding the HIGH-to-LOW transition of
LE. The TRI-STATE buffers are controlled by the Output
Enable (OE) input. When OE is LOW, the buffers are in the
bi-state mode. When OE is HIGH the buffers are in the high
impedance mode but this does not interfere with entering
new data into the latches.

The 'LS563 contains eight D-type latches with TRI-STATE
output buffers. When the Latch Enable (LE) input is HIGH,
data on the On inputs enters the latches. In this condition
the latches are transparent, i.e., a latch output will change
state each time its 0 input changes. When LE is LOW the
latches store the information that was present on the 0 in-

Truth Table

Functional Description
The LS574 consists of eight edge-triggered flip-flops with
individual D-type inputs and TRI-STATE true outputs. The
buffered clock and buffered Outputs Enable are common to
all flip-flops. The eight flip-flops will store the state of their
individual D inputs that meet the setup and hold times requirements on the LOW-to-HIGH Clock (CP) transition. With
the Output Enable (OE) LOW, the contents of the eight flipflops are available at the outputs. When the OE is HIGH, the
outputs go to the high impedence state. Operation of the
OE input does not affect the state of the flip-flops,

54LS670/DM54LS670/DM74LS670
TRI-STATE® 4-by-4 Register Files
General Description

These register files are organized as 4 words of 4 bits each,
and separate on-Chip decoding is provided for addressing
the four word locations to either write-in or retrieve data.
This permits writing into one location, and reading from another word location, simultaneously.
Four data inputs are available to supply the word to be
stored. Location of the word is determined by the write select inputs A and B, in conjunction with a write-enable signal. Data applied at the inputs should be in its true form.
That is, if a high level signal is desired from the output, a
high level is applied at the data input for that particular bit
location. The latch inputs are arranged so that new data will
be accepted only if both internal address gate inputs are
high. When this condition exists, data at the D input is transferred to the latch output. When the write-enable input, Gw,
is high, the data inputs are inhibited and their levels can
cause no change in the information stored in the internal
latches. When the read-enable input, GR, is high, the data
outputs are inhibited and go into the high impedance state.

and the read time (24 ns typical). The register file has a nonvolatile readout in that data is not lost when addressed.
All inputs (except read enable and write enable) are buffered to lower the drive requirements to one normal Series
54LS174LS load, and input clamping diodes minimize
switching transients to simplify system design. High speed,
double ended AND-OR-INVERT gates are employed for the
read-address function and have high sink current, TRISTATE outputs. Up to 128 of these outputs may be wireAND connected for increasing the capacity up to 512 words.
Any number of these registers may be paralleled to provide
n-bit word length.

Features
• Alternate Military/Aerospace device (54LS670) is available. Contact a National Semiconductor Sales Office/
Distributor for specifications.

The individual address lines permit direct acquisition of data
stored in any four of the latches. Four individual decoding
gates are used to complete the address for reading a word.
When the read address is made in conjunction with the
read-enable signal, the word appears at the four outputs.
This arrangement-data entry addressing separate from
data read addressing and individual sense line - eliminates
recovery times, permits simultaneous reading and writing,
and is limited in speed only by the write time (27 ns typical)

• For use as:
Scratch pad memory
Buffer storage between processors
Bit storage in fast multiplication designs
• Separate read/write addressing permits simultaneous
reading and writing
• Organized as 4 words of 4 bits
• Expandable to 512 words of n-bits
• TRI-STATE versions of DM54LS170/DM74LS170
• Fast access times 20 ns typ

Dual Rank 8-Bit TRI-STATE® Shift Registers
General Description

Features

These circuits are TRI-STATE, edge-triggered, 8-bit I/O registers in parallel with 8-bit serial shift registers which are
capable of operating in any of the following modes: parallel
load from I/O pins to register "A", parallel transfer down
from register "A" to serial shift register "S", parallel transfer
up from shift register "S" to register" A", serial shift of register "S", synchronously clear. Since the registers are edgetriggered by the positive transition of the clock, the control
lines which determine the mode or operation are completely
independent of the logic level applied to the clock. Designed for bus-oriented systems, these circuits have their
TRI-STATE inputs and outputs on the same pins.

• Registers are edge-triggered by the positive transition
of the clock
• All inputs are PNP transistors
• Input disable dominates over output disable
• Output high impedance state does not impede any other mode of operation
• 8-bit I/O pins are TRI-STATE buffers
• Typical shift frequency is 36 MHz

DM74LS962
Dual Rank 8-Bit TRI-STATE® Shift Registers
General Description

Features

These circuits are TRI-STATE, edge-triggered, S-bit I/O registers in parallel with S-bit serial shift registers which are
capable of operating in any of the following modes: parallel
load from I/O pins to register "A", parallel transfer down
from register "A" to serial shift register "8", parallel transfer
up from shift register "8" to register "A", serial shift of register "8", or exchange data between register "A" and shift
register "8". Since the registers are edge-triggered by the
positive transition of the clock, the control lines which determine the mode or operation are completely independent of
the logic level applied to the clock. Designed for bus-oriented systems, these circuits have their TRI-STATE inputs and
outputs on the same pins.

• Registers are edge-triggered by the positive transition
of the clock
• All inputs are PNP transistors
• Input disable dominates over output disable
• Output high impedance state does not impede any other mode of operation
• S-bit I/O pins are TRI-STATE buffers
• Typical shift frequency is 36 MHz
• Typical power dissipation is 305 mW
• All control inputs are active when in an "L" logic state
• Devices can be cascaded into N-bit word

96LS02/DM96LS02
Dual Retriggerable Resettable Monostable Multivibrator
General Description

Features

The 96LS02 is a dual retriggerable and resettable monostable multivibrator. The one-shot provides exceptionally wide
delay range, pulse width stability, predictable accuracy and
immunity to noise. The pulse width is set by an external
resistor and capacitor. Resistor values up to 1.0 M!l reduce
required capacitor values. Hysteresis is provided on both
trigger inputs of the 96LS02 for increased noise immunity.

• Required timing capacitance reduced by factors of 10
to 100 over conventional designs
• Broad timing resistor range-l.0 k!l to 2.0 M!l
• Output Pulse Width is variable over a 2000:1 range by
resistor control
• Propagation delay of 35 ns
• 0.3V hysteresis on trigger inputs
• Output pulse width independent of duty cycle
• 35 ns to 00 output pulse width range

Functional Description

Operation Notes

The 96LS02 dual retriggerable resettable monostable multivibrator has two DC coupled trigger inputs per function. one
active LOW (i0) and one active HIGH (11). The 11 input and
io Input of the 96LS02 utilize an internal Schmitt trigger with
hysteresis of 0.3V to provide increased noise immunity. The
use of active HIGH and LOW inputs allows either rising or
falling edge triggering and optional non-retriggerable operation. The inputs are DC coupled making triggering independent of input transition times. When input conditions for triggering are met. the a output goes HIGH and the external
capacitor is rapidly discharged and then allowed to recharge. An input trigger which occurs during the timing cycle
will retrigger the circuit and result in a remaining HIGH. The
output pulse may be terminated (a to the LOW state) at any
time by setting the Direct Clear input LOW. Retriggering may
be inhibited by tying the a output to io or the a output to 11.
Differential sensing techniques are used to obtain excellent
stability over temperature and power supply variations and a
feedback Darlington capacitor discharge circuit minimizes
pulse width variation from unit to unit. Schottky TTL output
stages provide high switching speeds and output compatibility with all TTL logic families.

TIMING
1. An external resistor (Rx) and an external capacitor (Cx)
are required as shown in the Logic Diagram. The value of
RX may vary from 1.0 kfl to 1.0 Mfl (96LS02).
2. The value of Cx may vary from 0 to any necessary value
available. If. however. the capacitor has significant leakage
relative to Vee/Rx the timing equations may not represent
the pulse width obtained.
3. Polarized capacitors may be used directly. The (+ ) termlnal of a polarized capacitor is connected to pin 1 (15). the
(-) terminal to pin 2(14) and Rx. Pin 1(15) will remain posltive with respect to pin 2(14) during the timing cycle.
4. The output pulse width tw for Rx ~ 10 kfl and Cx ~
1000 pF is determined as follows:
tw = 0.43 RxCx
Where Rx is in kfl. Cx is in pF. t is in ns or Rx is in kfl. Cx is
in p.F. t is in ms.
5. The output pulse width for Rx < 10 kfl or Cx < 1000 pF
should be determined from pulse width versus Cx or Rx
graphs.
6. To obtain variable pulse width by remote trimming. the
following circuit is recommended:

Operation Notes (Continued)
2. Input signals to the 96LS02 exhibiting slow or noisy transitions can use either trigger as both are Schmitt triggers.
3. When non-retriggerable operation is required, i.e., when
input triggers are to be ignored during quasi-stable state,
input latching is used to inhibit retriggering.
4. An overriding active LOW level direct clear is provided on
each multivibrator. By applying a LOW to the clear, any timing cycle can be terminated or any new cycle inhibited until
the LOW reset input is removed. Trigger inputs will not produce spikes in the output when the reset is held LOW. A
LOW-to-HIGH transition on Co will not trigger the 96LS02. If
the CD input goes HIGH coincident with a trigger transition,
the circuit will respond to the trigger.

7. Under any operating condition, Cx and Rx (Min) must be
kept as close to the circuit as possible to minimize stray
capacitance and reduce noise pickup.
8. Vee and ground wiring should conform to good high frequency standards so that switching transients on Vee and
ground leads do not cause interaction between one shots.
Use of a 0.01 I£F to 0.1 I£F bypass capacitor between Vee
and ground located near the circuit is recommended.
TRIGGERING
1. The minimum negative pulse width into io is 8.0 ns; the
minimum positive pulse width into 11 is 12 ns.

DM54S7 4/DM7 4S7 4
Dual Positive-Edge-Triggered D Flip-Flops
with Preset, Clear, and Complementary Outputs
General Description
This device contains two independent positive-edge-triggered D flip-flops with complementary outputs. The information on the D input is accepted by the flip-flops on the positive going edge of the clock pulse. The triggering occurs at a
voltage level and is not directly related to the transition time
of the rising edge of the clock. The data on the D input may

be changed while the clock is low or high without affecting
the outputs as long as setup and hold times are not violated.
A low logic level on the preset or clear inputs will set or
reset the outputs regardless of the logic levels of the other
inputs.

DM54S 112/DM7 4S 112 Dual Negative-Edge-Triggered
Master-Slave J-K Flip-Flops with Preset,
Clear, and Complementary Outputs
General Description
This device contains two independent negative-edge-triggered J-K flip-flops with complementary outputs. The J and
K data is processed by the flip-flops on the falling edge of
the clock pulse. The clock triggering occurs at a voltage
level and is not directly related to the transition time of the
negative going edge of the clock pulse. Data on the J and K

inputs can be changed while the clock is high or low without
affecting the outputs as long as setup and hold times are
not violated. A low logic level on the preset or clear inputs
will set or reset the outputs regardless of the logic levels of
the other inputs.

DM54S138/DM74S138, DM54S139/DM74S139
Decoders/Demultiplexers
General Description

Features

These Schottky-clamped circuits are designed to be used in
high-performance memory-decoding or data-routing applications, requiring very short propagation delay times. In
high-performance memory systems these decoders can be
used to minimize the effects of system decoding. When
used with high-speed memories, the delay times of these
decoders are usually less than the typical access time of the
memory. This means that the effective system delay introduced by the decoder is negligible.

• Designed specifically for high speed:
Memory decoders
Data transmission systems
• S138 3-to-8-line decoders incorporates 3 enable inputs
to simplify cascading and/or data reception
• S139 contains two fully independent 2-to-4-line decoders/demultiplexers
• Schottky clamped for high performance
• Typical propagation delay time (3 levels of logic)
S138 8 ns
S139 7.5 ns
• Typical power dissipation
S138 245 mW
S139 300 mW

The S138 decodes one-of-eight lines, based upon the conditions at the three binary select inputs and the three enable
inputs. Two active-low and one active-high enable inputs
reduce the need for external gates or inverters when expanding. A 24-line decoder can be implemented with no external inverters, and a 32-line decoder requires only one
inverter. An enable input can be used as a data input for
demultiplexing applications.
The S139 comprises two separate two-line-to-four-line decoders in a single package. The active-low enable input can
be used as a data line in demultiplexing applications.
All of these decoders/demultiplexers feature fully buffered
inputs, presenting only one normalized load to its driving
circuit. All inputs are clamped with high-performance
Schottky diodes to suppress line-ringing and simplify system
design.

DM54S174/DM74S174, DM54S175/DM74S175
Hex/Quad D Flip-Flops with Clear
General Description

Features

These positive-edge-triggered flip-flops utilize TTL circuitry
to implement D-type flip-flop logic. All have a direct clear
input, and the quad (175) versions feature complementary
outputs from each flip-flop.

•
•
•
•
•

Information at the D inputs meeting the setup time requirements is transferred to the Q outputs on the positive-going
edge of the clock pulse. Clock triggering occurs at a particular voltage level and is not directly related to the transition
time of the positive-going pulse. When the clock input is at
either the high or low level, the D input signal has no effect
at the output.

S174 contain six flip-flops with single-rail outputs.
S175 contain four flip-flops with double-rail outputs.
Buffered clock and direct clear inputs
Individual data input to each flip-flop
Applications include:
Buffer/storage registers
Shift registers
Pattern generators
• Typical clock frequency 110 MHz
• Typical power dissipation per flip-flop 75mW

DM54S181/DM74S181 Arithmetic Logic
Unit/Function Generators
General Description

Features

These arithmetic logic units (ALU)/function generators perform 16 binary arithmetic operations on two 4-bit words, as
shown in Tables 1 and 2. These operations are selected by
the four function-select lines (SO, 51, 52, 53) and include
addition, subtraction, decrement, and straight transfer.
When performing arithmetic manipulations, the internal carries must be enabled by applying a low-level voltage to the
mode control input (M). A full carry look-ahead scheme is
available in these devices for fast, simultaneous carry generation by means of two cascade-outputs (P and G) for the
four bits in the package. When used in conjunction with the
DM54S182/DM74S182 full carry look-ahead circuits, highspeed arithmetic operations can be performed. The typical
addition times shown below illustrate how little time is required for addition of longer words, when full carry lookahead is employed. The method of cascading 182 circuits
with these ALU's to provide multi-level full carry look-ahead
is illustrated under typical applications data for the
DM54S182/DM74S182.

General Description

(Continued)
If high speed is not important, a ripple-carry input (C n) and a
ripple-carry output (Cn+4) are available. However, the ripple-carry delay has also been minimized so that arithmetic
manipulations for small word lengths can be performed
without external circuitry.

relative magnitude information. Again, the ALU should be
placed in the subtract mode by placing the function select
inputs 53, 52, 51, SO at L, H, H, L, respectively.
These circuits have been designed to not only incorporate
all of the designer's requriements for arithmetic operations,
but also to provide 16 possible functions of two Boolean
variables without the use of external circuitry. These logic
functions are selected by use of the four function-select inputs (SO, 51, 52, 53) with the mode-control input (M) at a
high level to disable the internal carry. The 16 logiC functions are detailed in Tables 1 and 2 and include exclusiveOR, NAND, AND, NOR, and OR functions.

These circuits will accommodate active-high or active-low
data, if the pin designations are interpreted as shown below.
Subtraction is accomplished by 1's complement addition,
where the 1's complement of the subtrahend is generated
internally. The resultant output is A-B-1, which requires
an end-around or forced carry to provide A-B.
The 5181 can also be utilized as a comparator. The A = B
output is internally decoded from the function outputs (FO,
F1, F2, F3) so that when two words of equal magnitude are
applied at the A and B inputs, it will assume a high level to
indicate equality (A = B). The ALU should be in the subtract
mode with Cn = H when performing this comparison. The A
= B output is open-collector so that it can be wire-AND
connected to give a comparison for more than four bits. The
carry output (Cn + 4) can also be used to supply

ALU SIGNAL DESIGNATIONS
The DM545181/DM745181 can be used with the signal
designations of either Figure 1 or Figure 2.
The logic functions and arithmetic operations obtained with
signal designations as in Figure 1 are given in Table I; those
obtained with the signal designations of Figure 2 are given
in Table II.

DM54S 182/DM7 4S 182 Look-Ahead Carry Generators
General Description
These circuits are high-speed, look-ahead carry generators,
capable of anticipating a carry across four binary adders or
groups of adders. They are cascadable to perform full lookahead across n-bit adders. Carry, generate-carry, and propagate-carry functions are provided as shown in the pin designation table.
When used in conjunction with the 161 arithmetic logic unit,
these generators provide high-speed carry look-ahead capability for any word length. Each S162 generates the lookahead (antiCipated carry) across a group of four ALU's and,
in addition, other carry look-ahead circuits may be employed
to antiCipate carry across sections of four look-ahead packages up to n-bits. The method of cascading circuits to perform multi-level look-ahead is illustrated under typical application data.
Carry input and output of the ALU's are in their true form,
and the carry propagate (P) and carry generate (G) are in
negated form; therefore, the carry functions (inputs, outputs,

DM54S 194/DM7 4S 194
4-Bit Bidirectional Universal Shift Registers
Shift right is accomplished synchronously with the rising
edge of the clock pulse when SO is high and 51 is low.
Serial data for this mode is entered at the shift-right data
input. When SO is low and 51 is high, data shifts left synchronously and new data is entered at the shift-left serial
input.

General Description
These bidirectional shift registers are designed to incorporate virtually all of the features a system designer may want
in a shift register; they feature parallel inputs, parallel outputs, right-shift and left-shift serial inputs, operating-modecontrol inputs, and a direct overriding clear line. The register
has four distinct modes of operation, namely:

Clocking of the flip-flop is inhibited when both mode control
inputs are low.

Parallel (broadside) load
Shift right (in the direction QA toward QD)
Shift left (in the direction 00 toward OA)
Inhibit clock (do nothing)

Features
• Parallel inputs and outputs
• Four operating modes:
Synchronous parallel load
Right shift
Left shift
Do nothing
• Positive edge-triggered clocking
• Direct overriding clear
• Typical clock frequency 105 MHz
• Typical power dissipation 425 mW

Synchronous parallel loading is accomplished by applying
the four bits of data and taking both mode control inputs, SO
and 51, high. The data are loaded into the associated flipflops and appear at the outputs after the positive transition
of the clock input. During loading, serial data flow is inhibited.

DM54S195/DM74S195 4-Bit Parallel Access
Shift Registers
General Description
These 4-bit registers feature parallel inputs, parallel outputs,
J-K serial inputs, shiftlload control input, and a direct overriding clear. All inputs are buffered to lower the input drive
requirements. The registers have two modes of operation:

The high-performance S195, with a 105 MHz typical shift
frequency, is particularly attractive for very high-speed data
processing systems. In most cases existing systems can be
upgraded merely by using this Schottky-clamped shift register.

Parallel (broadside) load
Shift (in the direction QA toward Qo)

Features

Parallel loading is accomplished by applying the four bits of
data and taking the shiftlload control input low. The data is
loaded into the associated flip-flop and appears at the outputs after the positive transition of the clock input. During
loading, serial data flow is inhibited.

•
•
•
•

Synchronous parallel load
Positive-edge-triggered clocking
Parallel inputs and outputs from each flip-flop
Direct overriding clear
J and K inputs to first stage
Complementary outputs from last stage
For use in high-performance:
accumulators/processors
serial-to-parallel, parallel-to-serial converters
Typical clock frequency 105 MHz
Typical power dissipation 350 mW

•

Shifting is accomplished synchronously when the shiftlload
control input is high. Serial data for this mode is entered at
the J-K inputs. These inputs permit the first stage to perform
as a J-K, D, or T-type flip-flop as shown in the truth table.

The strobe must be at a low logic level to enable these devices. The TRI-STATE outputs permit direct connection to a common bus. When the strobe input is high, both outputs are in a high-impedance state in which both the upper and lower transistors of each totem pole output are off, and the output neither drives nor loads the bus significantly. When the strobe is low, the outputs are activated and operate as standard TTL totempole outputs. • • • • • • TRI-STATE version of S151 Interface directly with system bus Perform parallel-to-serial conversion Permit multiplexing from N-lines to one line Complementary outputs provide true and inverted data Max no. of common outputs 54S 39 74S 129 • Typical propagation delay time (0 to Y) 8 ns • Typical power dissipation 275 mW To minimize the possibility that two outputs will attempt to take a common bus to opposite logic levels, the output control circuitry is designed so that the average output disable time is shorter than the average output enable time.

With all but one of the common outputs disabled (at a high impedance state), the low impedance of the single enabled output will drive the bus line to a high or low logic level. To minimize the possibility that two outputs will attempt to take a common bus to opposite logic levels, the output enable circuitry is designed such that the output disable times are shorter than the output enable times. This TRI-STATE output feature means that n-bit (paralleled) data selectors with up to 258 sources can be implemented for data buses. It also permits the use of standard TTL registers for data retention throughout the system. • TRI-STATE versions S157, S158, with same pin-outs • Schottky-clamped for significant improvement in A-C performance • Provides bus interface from multiple sources in highperformance systems • Average propagation delay from data input S257 4.8 ns S2584 ns • Typical power dissipation 5257320 mW S258 280 mW Connection Diagrams Dual-In-Llne Package Dual-In-Line Package INPUTS A3 11 2 SELECT A1 3 B3 INPUTS OUTPUT B4 VCC CONTROL A4 OUTPUT V3 10 9 l16 15 4 V1 ~--~' OUTPUT INPUTS A1 13 14 2 SELECT B1 OUTPUT V4 3 12 4 B1 Y1 ~ OUTPUT , INPUTS 11 5 A2 6 B2 ~ TL/F/6462-1 Function Table Inputs H L L L L 10 9 .18 7 Y2 GND OUTPUT TLlF/6482-2 Order Number DM54S257J, DM54S258J, DM54S257W, DM74S257N or DM74S258N See NS Package Number J16A, N16E or W16A Output Control OUTPUT V3 B3 A3 OutputY Select A B S257 S258 X L L X L Z H H X X X X X L L Z H L H H L H H = High Level.

The word-length capability Is easily expanded by cascading. Input buffers are provided so that each input represents only one normal 74S load, and full fan-out to 10 normal Series 74S loads is available from each of the outputs at low logic levels. A fan-out to 20 normal Series 74S loads is provided at high logic levels, to facilitate connection of unused inputs to used inputs. The S280 can be used to upgrade the performance of most systems utilizing the DM74180 parity generator/checker. Although the S280 is implemented without expander inputs, the corresponding function is provided by the availability of all input at pin 4, and no internal connection at pin 3. This permits the S280 to be substituted for the 180 in existing designs to produce an identical function, even if S280's are mixed with existing 180's.

The sum (l:) outputs are provided for each bit and the resultant carry (C4) is obtained from the fourth bit. These adders feature full internal look ahead across all four bits. This provides the system designer with partial lookahead performance at the economy and reduced package count of a ripple-carry implementation. • Full-carry look-ahead across the four bits • Systems achieve partial look-ahead performance with the economy of ripple carry • Typical add times Two B-bit words 15 ns Two 16-bit words 30 ns • Typical power dissipation 510 mW The adder logic, including the carry, is implemented in its true form meaning that the end-around carry can be accomplished without the need for logic or level inversion.

Two function-select inputs and two output-control inputs can be used to choose the modes of operation listed in the function table. • Multiplexed inputs/outputs provide improved bit density • Four modes of operation: Hold (Store) Shift Left Shift Right Load Data • TRI-STATE outputs drive bus lines directly • Can be cascaded for N-bit word lengths • Operates with outputs enabled or at high Z • Guaranteed shift (clock) frequency 50 MHz • Typical power dissipation 700 mW Synchronous parallel loading is accomplished by taking both function-select lines, SO and 51, high. This places the TRI-STATE outputs in a high-impedance state, which permits data that is applied on the input/output lines to be clocked into the register. Reading out of the register can be accomplished while the outputs are enabled in any mode. A direct overriding input is provided to clear the register whether the outputs are enabled or off.

A buffered output control input can be used to place the eight outputs in either a normal logic state (high or low logic levels) or a high-impedance state. In the high-impedance state the outputs neither load nor drive the bus lines Significantly. These a-bit registers feature totem-pole TRI-STATE outputs designed specifically for driving highly-capacitive or relatively low-impedance loads. The high-impedance state and increased high-logic-level drive provide these registers with the capability of being connected directly to and driving the bus lines in a bus-organized system without need for interface or pull-up components. They are particularly attractive for implementing buffer registers, I!O ports, bidirectional bus drivers, and working registers. The eight latches of the DM5417 4S373 are transparent D-type latches meaning that while the enable (G) is high the Q outputs will follow the data (D) inputs. When the enable is taken low the output will be latched at the level of the data that was set up. The output control does not affect the internal operation of the latches or flip,flops. That is, the old data can be retained or new data can be entered even while the outputs are off. Features • Choice of a latches or a D-type flip-flops in a single package • TRI-STATE bus-driving outputs • Full parallel-access for loading • Buffered control inputs • P-N-P input reduce D-C loading on data lines The eight flip-flops of the DM54!74S374 are edge-triggered D-type flip-flops. On the positive transition of the clock, the Q outputs will be set to the logic states that were set up at the D inputs.

These operations are selected by the three functionselect lines (SO, 51, S2). A full carry look-ahead circuit is provided for fast, simultaneous carry generation by means of two cascade outputs (p and G) for the four bits in the package. The method of cascading 5451821745182 lookahead carry generators with these ALU's to provide multilevel full carry look-ahead is illustated under typical applications data for the '5182. The typical addition times shown illustrate the short delay time required for addition of longer words when full look-ahead is employed. The eXClUSive-OR, AND, or OR function of two Boolean variables is provided without the use of external circuitry. Also, the outputs can be either cleared (low) or preset (high) as desired. • A fully parallel 4-Bit ALU in 20-pin package for 0.300inch row spacing • Ideally suited for high-density economical processors • Parallel inputs and outputs and full look-ahead provide system flexibility • Arithmetic and logic operations selected specifically to simplify system implementation: A minus B B minus A A pius B and five other functions • Schottky-clamped for high performance 16-bit add time ... 26 ns typ using look-ahead 32-bit add time ... 34 ns typ using look-ahead Connection Diagram Pin Designations Dual-In-Llne Package INPUTS Vee 120 A2 b9 B2 -1~8 A3 117 I I A2 B2 A3 OUTPUTS B3 1,8 en 1,5 ji G F3 114 ~3 1'2 1 AI en p G F3 Designation Pin Nos_ Function A3, A2, A1, AO 17,19,1,3 Word A Inputs B3,B2,B1,BO 16,18,2,4 Word B Inputs 52,51,50 7,6,5 Function-Select Inputs Cn 15 Carry Input for Addition, Inverted Carry Input for Subtraction F3,F2,F1,FO 12,11,9,8 Function Outputs is 14 Inverted Carry Propagate Output G 13 Inverted Carry Generated Output Vee 20 Supply Voltage GND 10 Ground F2 AO BO Ij2 I so SI S2 FO Fl I I I I I 13 Bl 11 I I I I I B3 AI Bl F2 14 AO BO J.5 so INPUTS 16 SI J' S2 18 19 -FO F1 __1'0 GND OUTPUTS TL/F/6487-1 Order Number DM74S381N See NS Package Number N20A Function Table Selection H S2 S1 SO L L L L H H H H L L H H L L H H L H L H L H L H Arithmetic/Logic Operation CLEAR BMINUSA A MINUS B A PLUS B AGlB A+B AB PRESET = high level, L = low level 3-135 • Absolute Maximum Ratings (Note) Supply Voltage Input Voltage Operating Free Air Temperature Range Storage Temperature Range Note: The "Absolute Maximum Ratings" are those values beyond which the safety of the device cannot be guarant88d.

When the PE input is LOW, the DM93S00 appears as four common clocked D flip-flops. The data on the parallel inputs PO-P3 is transferred to the respective 00-03 outputs following the LOW-to-HIGH clock transition. Shift left operation (03 - 02) can be .achieved by tying the an outputs to the Pn-1 inputs and holding the PE input LOW. The Logic Diagrams and Truth Table indicate the functional characteristics of the DM93S00 4-bit shift register. The device is useful in a wide variety of shifting, counting and storage applications. It performs serial, parallel, serial-to-parallei, or parallel-to-serial data transfers. The DM93S00 has two primary modes of operation, shift right (00 - 01) and parallel load, which are controlled by the state of the Parallel Enable (PE) input. When the PE input is HIGH, serial data enters the first flip-flop 00 via the J and K inputs and is shifted one bit in the direction 00 - 01 - 02 - 03 following each LOW-to-HIGH clock transition. The JK inputs provide the flexibility of the JK type input for special applications, and the simple All serial and parallel data transfers are synchronous, occuring after each LOW-to-HIGH clock transition. Since the DM93S00 utilizes edge triggering, there is no restriction on the activity of the J, K, Pn and PE inputs for logic operation-except for the setup and release time requirements. A LOW on the asynchronous Master Reset (MR) input sets all a outputs LOW, independent of any other input condition.

Controlled by the four Function Select inputs (SO-S3) and the Mode Control input (M), it can perform all the 16 possible operations or 16 different arithmetic operations on active HIGH or active LOW operands. The Function Table below lists these operations. When the Mode Control input (M) is HIGH, all internal carries are inhibited and the device performs logic operations on the individual bits as listed. When the Mode Control input is LOW, the carries are enabled and the device performs arithmetic operations on the two 4-bit words. The device incorporates full internal carry lookahead and provides for either ripple carry between devices using the Cn +4 output, or for carry lookahead between packages using the signals j5 (Carry Propagate) and G (Carry Generate). j5 and G are not affected by carry in. When speed requirements are not stringent, the DM93S41 can be used in a simple ripple carry mode by connecting the Carry output (C n+ 4) signal to the Carry input (Cn) of the next unit. For super high speed operation the Schottky DM93S41 should be used in conjunction with the' 42 carry lookahead circuit. The A = B output from the DM93S41 goes HIGH when all four Fn outputs are HIGH and can be used to indicate logic equivalence over four bits when the unit is in the subtract mode. The A = B output is open-collector and can be wired-AND with the other A = B outputs to give a comparison for more than four bits. The A = B signal can also be used with the Cn +4 signal to indicate A > B and A < B. The Function Table lists the arithmetic operations that are performed without a carry in. An incoming carry adds a one to each operation. Thus select code LHHL generates A minus B minus 1 (2s complement notation) without a carry in and generates A minus B when a carry is applied. Because subtraction is actually performed by complementary addition (ls complement), a carry out means borrow; thus a carry is generated when there is no underflow and no carry is generated when there is underflow. As indicated the '41 can be used with either active LOW inputs producing active LOW outputs or with active HIGH inputs producing active HIGH outputs. For either case the table lists the operations that are performed to the operands labeled inside the logic symbol.

It multiplies a multiplicand of four bits by a multiplier of two bits and forms a basic iterative logic cell. It can also multiply in active HIGH (positive logic) or active LOW (negative logic) representations by reinterpreting the active levels of the inputs, outputs and the Polarity Control (P). The binary number with 1 as the most significant bit is treated as a negative number represented in twos complement form. These DM93S43 iterative logic cells can be connected to imple- ment multiplication of an X-bit number by a V-bit number. This application requires X • Y + 4 • 2 packages and the resulting product has X + Y bits. At the beginning of the array, a constant can be presented at the K inputs that will be added to the least significant part of the product. The packages can be connected in parallel, triangular or split-array scheme depending on the speed requirement. The '41 ALU can be used with these multipliers in the split-array scheme to obtain high speed multiplication. 3-151 ~ .---------------------------------------------------------------------~ ~ TABLE I.

When enabled (E input LOW), the A = B output is HIGH if the two 6-bit words are equal. When disabled (E input HIGH), the A = B output is forced HIGH. Equality is determined by Exclusive-NOR circuits which individually compare the equivalent bits from each word. Since the A = B output state is determined by the equality of each pair of inputs, the equivalent An and Bn pins can be interchanged to facilitate board layout or wiring. The active LOW Enable (E) can be used as a high speed strobe. When the Enable is HIGH, the A = B output is forced HIGH. This allows devices tied to a common wired-OR (actually wired-AND) node to be strobed individually or in groups. Only the enabled devices will determine the state of the output node.

It is intended primarily for error detection in systems which transmit data in B-bit bytes, but it can be expanded to any number of data inputs. Both even and odd parity outputs are available to allow maximum flexibility for both parity generation and parity checking. When the device is enabled (E = LOW), the Even Parity output (PE) Is HIGH when an even number of inputs is HIGH, and the Odd Parity output (PO) is HIGH when an odd number of Inputs is HIGH. The active LOW Enable (E) controls the state of both outputs; when the Enable (E) is HIGH, both outputs will be LOW. The Enable may be used to strobe the outputs at very high speeds to synchronize or inhibit the parity data. The DM93S62 has been designed with two sections using Exclusive-NOR comparison techniques. Eight data inputs 10-17 represent one section which will generate a parity bit in 16 ns to 20 ns. The ninth input (IB) bypasses three levels of logic and switches the outputs in 6.0 ns to 9.0 ns. This feature may be used to compensate for delayed arrival of the parity bit, allowing faster system cycle times (Figure a). The fast IB input is also useful when more than nine bits are to be checked. The output of one DM93S62 drives the IB input of a second DM93S62, providing a 17-bit parity check in 29 ns (typ). When some inputs of the DM93S62 are not used, such as for words of less than nine bits or when using parallel expansion techniques, there is an optimum delay scheme for termination of the unused inputs (see Table II). In essence, if one of the inputs of any Exclusive-NOR stays HIGH, the delay from the other input to the output is minimized. 3-162 TABLE II.

The 11 input utilizes an internal Schmitt trigger with hysteresis of 0.3V to provide increased noise Immunity. The use of active HIGH and LOW Inputs allows either rising or falling edge triggering and optional non-retriggerable operation. The Inputs are DC coupled making triggering independent of input transition times. When input conditions for triggering are met the 0 output goes HIGH and the external capacitor is rapidly discharged and then allowed to recharge. An input trigger which occurs during the timing cycle will retrigger the circuit and result in 0 remaining HIGH. The output pulse may be terminated (0 to the LOW state) at any time by setting the Direct Clear input LOW. Retriggering may be inhibited by tying the Q output to io or the 0 output to 11. Differential sensing techniques are used to obtain excellent stability over temperature and power supply variations and a feedback Darlington capacitor discharge circuit minimizes pulse width variation from unit to unit. Schottky TTL output stages provide high switching speeds and output compatibility with all TTL logic families. 3-168 , - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - , U) en en Operation Notes TIMING 1. An external resistor (Rx) and an external capacitor (Cx) are required as shown in the Logic Diagram. The value of Rx may vary from 1.0 k!l to 2.0 M!l (DM96S02). 2. The value of Cx may vary from 0 to any necessary value available. If, however, the capacitor has significant leakage relative to Vee/Rx the timing equations may not represent the pulse width obtained. 3. Polarized capacitors may be used directly. The ( +) terminal of a polarized capacitor is connected to pin 1(15), the (-) terminal to pin 2(14) and Rx. Pin 1(15) will remain positive with respect to pin 2(14) during the timing cycle. However, during quiescent (non-triggered) conditions, pin 1(15) may go negative with respect to pin 2(14) depending on values of Rx and Vee. For values of Rx ~ 10 k!l the maximum amount of capacitor reverse polarity, pin 1(15) negative with respect to pin 2(14) is 500 mV. Most tantalum electrolytic capacitors are rated for safe reverse bias operation up to 5% of their working forward voltage rating; therefore, capaCitors having a rating of 10 WVdc or higher should be used with the DM96S02 when Rx ~ 10 k!l. 4. The output pulse width tw for Rx ~ 10 k!l and Cx ~ 1000 pF is determined as follows: tw = 0.55 RxCx Where Rx is in k!l, Cx is in pF, t is in ns or RTX is in k!l, Cx is in p.F, t is in ms. 5. The output pulse width for RX < 10 k!l or Cx < 1000 pF should be determined from pulse width versus Cx or Rx graphs. 6. To obtain variable pulse width by remote trimming, the following circuit is recommended: 7. Under any operating condition, Cx and Rx (Min) must be kept as close to the circuit as possible to minimize stray capacitance and reduce noise pickup. 8. Vee and ground wiring should conform to good high frequency standards so that switching transients on Vee and ground leads do not cause interaction between one shots. Use of a 0.01 p.F to 0.1 p.F bypass capaCitor between Vee and ground located near the circuit is recommended. TRIGGERING 1. The minimum negative pulse width into io is 8.0 ns; the minimum positive pulse width into 11 is 12 ns. 2. Input signals to the DM96S02 exhibiting slow or noisy transitions should use the positive trigger input 11 which contains a Schmitt trigger. Input signals to the 96LS02 exhibiting slow or noisy transitions can use either trigger as both are Schmitt triggers. 3. When non-retriggerable operation is required, i.e., when input triggers are to be ignored during quasi-stable state, input latching is used to inhibit retriggering. 4. An overriding active LOW level direct clear is provided on each multivibrator. By applying a LOW to the clear, any timing cycle can be terminated or any new cycle inhibited until the LOW reset input is removed. Trigger inputs will not produce spikes in the output when the reset is held LOW. A LOW-to-HIGH transition on CD will not trigger the DM96S02.

The J and K data is processed by the flip-flop after a complete clock pulse. While the clock is low the slave is isolated from the master. On the positive transition of the clock, the data from the J and K inputs is transferred to the master. While the clock is high the J and K inputs are disabled. On the negative transition of the clock, the data from the master is trans- ferred to the slave. The logic state of J and K inputs must not be allowed to change while the clock is high. The data is transfered to the outputs on the falling edge of the clock pulse. A low logic level on the preset or clear inputs will set or reset the outputs regardless of the logic levels of the other inputs. Features • Alternate Military/Aerospace device (5476) is available.

Note that with active HIGH inputs, Carry In can not be left open, but must be held LOW when no carry in is intended.

Three fully-decoded decisions about two 4-bit words (A, B) are made and are externally available at three outputs. These devices are fully expandable to any number of bits without external gates. Words of greater length may be compared by connecting comparators in cascade. The A > B, A < B, and A = B outputs of a stage handling less-significant bits are connected to the corresponding inputs of the next stage handling more-significant bits. The stage handling the least-significant bits must have a high-level voltage applied to the A = B input. The cascading paths are implemented with only a two-gate-Ievel delay to reduce overall comparison times for long words. Features • Typical power dissipation 275 mW • Typical delay (4-bit words) 23 ns • Alternate Military/Aerospace device (5485) is available.

An internal 2kO timing resistor is provided for design convenience minimizing component count and layout problems. This device can be used with a single external capacitor. Inputs (A) are active-low trigger transition inputs and input (8) is an active-high transition Schmitt-trigger input that allows jitter-free triggering from inputs with transition rates as slow as 1 volt/second. A high immunity to Vcc noise of typically 1.5V is also provided by internal circuitry at the input stage. • • • • • • • Jitter free Schmitt-trigger input Excellent noise immunity typically 1.2V Stable pulse width up to 90% duty cycle TTL, DTL compatible Compensated for Vee and temperature variations Input clamp diodes Alternate Military/Aerospace device (54121) is available. Contact a National Semiconductor Sales Office/ Distributor for specifications. Functional Description • Triggered from active-high transition or active-low transition inputs • Variable pulse width from 30 ns to 28 seconds The basic output pulse width is determined by selection of an internal resistor RINT or an external resistor (Rx) and capacitor (Cx). Once triggered the output pulse width is independent of further transitions of the inputs and is a function of the timing components. Pulse width can vary from a few nano-seconds to 28 seconds by choosing appropriate Rx and Cx combinations. There are three trigger inputs from the device, two negative edge-triggering (A) inputs, one positive edge Schmitt-triggering (8) input.

When the circuit is in the quasi-stable (delay) state, another trigger applied to the inputs (per Truth Table) will cause the delay period to start again, without disturbing the outputs. This process can be repeated indefinitely and thus the output pulse period (0 HIGH, LOW) can be made as long as desired. Alternatively, a delay period can be terminated by a LOW signal applied to Co, which also prevents triggering. An internal connection from Co to the input gate makes it possible to trigger the circuit by a positive-going signal on Co, as shown in the Truth Table. For timing capacitor values greater than 1000 pF, the output pulse width is defined as follows: Connection Diagram Logic Symbol Iw = 0.32 RxCx (1.0 + 0.7/Rx) Where tw is in ns, Rx is in kn and Cx is in pF. a 13 11 Dual-In-Llne Package 14 Vee A2 2 13 RxCx NC Al 81 3 12 82 4 11 CD 5 10 Q 6 9 GND 7 8 3 4 RINT Q 5 TLlF/10212-2 Vee = Pin 14 GNO = Pin 7 NC = Pins 10 and 12 TLlF/10212-1 Pin Names Al,A2 8 1,82 0,0 6 Cx NC Order Number 54122DMQB, 54122FMQB or DM74122N See NS Package Number J14A, N14A or W14B Co 8 1 2 Description Trigger Inputs (Active Falling Edge) Trigger Inputs (Active Rising Edge) Direct Clear Inputs (Active LOW) Outputs 4-120 ......

Each device has three inputs permitting the choice of either leading-edge or trailing edge triggering. Pin (A) is an activelow transition trigger input and pin (8) is an active-high transition trigger input. The clear (ClR) input terminates the output pulse at a predetermined time independent of the timing components. • DC triggered from active-high transition or active-low transition inputs • Retriggerable to 100% duty cycle • Direct reset terminates output pulse • Compensated for Vee and temperature variations • DTl, TTL compatible • Input clamp diodes National's '123 device features a unique logic realization not implemented by other manufacturers. The "Clear" input will not trigger the device, a design tailored for applications where it shall only terminate or reduce a liming pulse. To obtain the besl and trouble free operation from this device please read the operating rules as well as the NSC one-shot application notes carefully and observe recommendations. Functional Description The basic output pulse width is determined by selection of an external resistor (Rx) and capaCitor (Cx). Once triggered, the basic pulse width may be extended by retriggering the gated active-low transition or active-high transition inputs or be reduced by use of the active-low transition clear input. Retriggering to 100% duty cycle is possible by application of an input pulse train whose cycle time is shorter than the output cycle time such that a continuous "HIGH" logic state is maintained at the "a" output.

This device contains four independent gates each of which performs a non-inverting buffer function. The outputs have the TRI-STATE feature. When enabled, the outputs exhibit the low impedance characteristics of a standard TTL output with additional drive capability at the high Logic level to permit the driving of bus lines without external pull-up resistors. When disabled, both the output transistors are turned off presenting a high-impedance state to the bus line. Thus the output will act neither as a significant load nor as a driver.

The inverters are connected in pairs to make BCD input data available for decoding by the NAND gates. Full decoding of BCD input logic ensures that all outputs remain off for all invalid (1015) binary input conditions. These decoders feature highperformance, NPN output transistors designed for use as indicator/relay drivers, or as open-collector logic-circuit drivers. The high-breakdown output transistors are compatible for interfacing with most MOS integrated circuits. • Full decoding of input logic • 80 mA sink-current capability • All outputs are off for invalid BCD input conditions Connection Diagram Function Table Dual-In-Llne Package INPUTS \ B A 15 C 14 D , OUTPUTS 9 8 11 12 13 NO.~_I_n~pu_t_8__+-________0_u_t~p_ut_8________~ DeB A 0 1 2 3 4 5 6 7 8 9 7 10 o L L L L L H H H H H H H H H 9 L L L L 5 L 6 L 7 L B H 9 H I H N H V H A H L H I H 1 2 3 4 3 2 o \ 2 5 4 3 4 7 6 5 6 18 GND OUTPUTS TLlF/6544-1 Order Number DM54145J, DM54145W or DM74145N See NS Package Number J16A, N16E or W16A L L L H H H H L L L L H H H H L H H L L H H L L H H L L H H H L H L H L H L H L H L H L H H H H H H H H H H H H H H H H L H H H H H H H H H H H H H H H L H H H H H H H H H H H H H H H L H H H H H H H H H H H H o H 4-134 = High Level (Off).

The 150 selects one-of-sixteen data sources; the 151 A selects one-of-eight data sources. The 150 and 151A have a strobe input which must be at a low logic level to enable these devices. A high level at the strobe forces the W output high and the Y output (as applicable) low. The 151 A features complementary Wand Y outputs, whereas the 150 has an inverted (W) output only. • • • • • • The 151 A incorporates address buffers which have symmetrical propagation delay times through the complementary paths. This reduces the possibility of transients occurring at the output(s) due to changes made at the select inputs, even when the 151A outputs are enabled (i.e., strobe low). 150 selects one-of-sixteen data lines 151A selects one-of-eight data lines Performs parallel-to-serial conversion Permits multiplexing from N lines to one line Also for use as Boolean function generator Typical average propagation delay time, data input to W output 150 11 ns 151A 9 ns • Typical power dissipation 150 200 mW 151A 135 mW • Alternate Military/Aerospace device (54150, 54151A) is available.

The demultiplexing function is performed by using the 4 input lines to address the output line, passing data from one of the strobe inputs with the other strobe input low. When either strobe input is high, all outputs are high. These demultiplexers are ideally suited for implementing high-performance memory decoders.

When both sections are enabled by the strobes, the common address inputs sequentially select and route associated input data to the appropriate output of each section. The individual strobes permit activating or inhibiting each of the 4-bit sections as desired. Data applied to input C1 is inverted at its outputs and data applied at C2 is true through its outputs. The inverter following the C1 data input permits use as a 3-to-S-line decoder, or 1-to-S-line demultiplexer, without external gating. Input clamping diodes are provided on these circuits to minimize transmission-line effects and simplify system design.

The 161A and 163A are 4-bit binary counters. The carry output is decoded by means of a NOR gate, thus preventing spikes during the normal counting mode of operation. Synchronous operation is provided by having all f1ipflops clocked simultaneously so that the outputs change coincident with each other when so instructed by the countenable inputs and internal gating. This mode of operation eliminates the output counting spikes which are normally associated with asynchronous (ripple clock) counters. A buffered clock input triggers the four flip-flops on the rising (positive-going) edge of the clock input waveform. These counters are fully programmable; that is. the outputs may be preset to either level. As presetting is synchronous, setting up a low level at the load input disables the counter and causes the outputs to agree with the setup data after the next clock pulse, regardless of the levels of the enable input. Low-to-high transitions at th910ad input of the 161A and 163A are perfectly acceptable, regardless of the logic levels on the cloCk or enable inputs. The clear function for the 161 A is asynchronous; and a low level at the clear input sets all four of the flip-flop outputs low, regardless of the levels of clock, load, or enable inputs. The clear function for the 163A is synchronous; and a low level at the clear input sets all four of the flip-flop outputs low after the next clock pulse, regardless of the levels of the enable inputs. This synchronous clear allows the count length to be modified easily, as decoding the maximum count desired can be accomplished with one external NAND gate. The gate out- put is connected to the clear input to synchronously clear the counter to all low outputs. Low-to-high transitions at the clear input of the 163A are also permissible, regardless of the logic levels on the clock, enable, or load inputs. The carry look-ahead circuitry provides for cascading counters for n-bit synchronous applications without additional gating. Instrumental in accomplishing this function are two count-enable inputs and a ripple carry output. Both countenable inputs (P and T) must be high to count, and input T is fed forward to enable the ripple carry output. The ripple carry output thus enabled will produce a high-level output pulse with a duration approximately equal to the high-level portion of the QA output. This high-level overflow ripple carry pulse can be used to enable successive cascaded stages. Highto-low-level transitions at the enable P or T inputs of the 161A through 163A may occur, regardless of the logic level on the clock. Features II Synchronously programmable • • • • • ..

These operations are selected by the four function-select lines (SO, S1, S2, S3) and include addition, subtraction, decrement, and straight transfer. When performing arithmetic manipulations, the internal carries must be enabled by applying a low-level voltage to the mode control input (M). A full carry look-ahead scheme is available in these devices for fast, simultaneous carry generation by means of two cascade-outputs (P and G) for the four bits in the package. When used in conjunction with the DM54S182 full carry look-ahead circuits, high-speed arithmetic operations can be performed. The typical addition times shown below illustrate how little time is required for addition of longer words, when full carry look-ahead is employed. The method of cascading 182 circuits with these ALU's to provide multi-level full carry look-ahead is illustrated under typical applications data for the DM54S182.

CD .... General Description (Continued) If high speed is not important, a ripple-carry input (Cn> and a ripple-carry output (C n + 4) are available. However, the ripple-carry delay has also been minimized so that arithmetic manipulations for small word lengths can be performed without external circuitry. These circuits will accommodate active-high or active-low data, if the pin designations are Interpreted as shown below. Subtraction Is accomplished by 1's complement addition, where the 1's complement of the subtrahend is generated internally. The resultant output is A-B-1, which requires an end-around or forced carry to provide A-B. The 181 can also be utilized as a comparator. The A = B output is internally decoded from the function outputs (FO, F1, F2, FS) so that when two words of equal magnitude are applied at the A and B inputs, it will assume a high level to indicate equality (A = B). The ALU should be in the subtract mode with Cn = H when performing this comparison. The A = B output is open-collector so that it can be wire-AND connected to give a comparison for more than four bits. The carry output (Cn +4) can also be used to supply relative magnitude information. Again, the ALU should be placed in the subtract mode by placing the function select inputs SS, 52, 51, SO at L, H, H, L, respectively. These circuits have been designed to not only incorporate all of the designer's requirements for arithmetic operations, but also to provide 16 possible functions of two Boolean variables without the use of external circuitry. These logic functions are selected by use of the four function-select inputs (SO, 51, 52, 53) with the mode-control input (M) at a high level to disable the internal carry. The 16 logic functions are detailed in Tables 1 and 2 and include exclusiveOR, NAND, AND, NOR, and OR functions. ALU SIGNAL DESIGNATIONS The DM54181 can be used with the signal designations of either Figure 1 or Figure 2.

CD ~ Semiconductor en DM74184/DM74185A BCD-to-Binary and Binary-to-BCD Converters General Description These monolithic converters are derived from the 256-bit read only memories, DM5488, and DM7488. Emitter con· nections are made to provide direct read·out of converted codes at outputs V8 through Vl, as shown in the function tables. These converters demonstrate the versatility of a read only memory in that an unlimited number of reference tables or conversion tables may be built into a system. Both of these converters comprehend that the least significant bits (LSB) of the binary and BCD codes are logically equal, and In each case the LSB bypasses the converter as iIIus· trated in the typical applications. This means that a 6-bit converter is produced in each case. Both devices are cas· cadable to N bits. An overriding enable input is provided on each converter which when taken high inhibits the function, causing all out· puts to go high. For this reason, and to minimize power consumption, unused outputs V7 and V8 of the 185A and all "don't care" conditions of the 184 are programmed high. The outputs are of the open·collector type. b. Shift right, examine, and correct after each shift until the least significant decade contains a number smaller than eight and all other converted decades contain zeros. In addition to BCD·to·binary conversion, the DM74184 is programmed to generate BCD 9's complement or BCD 10's complement. Again, in each case, one bit of the comple· ment code is logically equal to one of the BCD bits; there· fore, these complements can be produced on three lines. As outputs V6, V7 and V8 are not required in the BCD·to·bi· nary conversion, they are utilized to provide these comple· ment codes as specified in the function table when the de· vices are connected as shown. DM74185A BINARY-TO-BCD CONVERTERS The function performed by these 6-bit binary·to·BCD con· verters is analogous to the algorithm: a. Examine the three most significant bits. If the sum is greater than four, add three and shift left one bit. DM74184 BeD·TO-BINARY CONVERTERS b. Examine each BCD decade. If the sum is greater than four, add three and shift left one bit. The 6-bit BCD·to·binary function of the DM74184 is analo· gous to the algorithm: c. Repeat step b until the least·significant binary bit is in the least·significant BCD location. a. Shift BCD number right one bit and examine each dec· ade. Subtract three from each 4-bit decade containing a binary value greater than seven.

The 191 is a 4-bit binary counter. Synchronous operation is provided by having all flip-flops clocked simultaneously so that the outputs change simultaneously when so instructed by the steering logic. This mode of operation eliminates the output counting spikes normally associated with asynchronous (ripple clock) counters. The outputs of the four master-slave flip-flops are triggered on a low-to-high level transition of the clock input, if the enable input is low. A high at the enable input inhibits counting. Level changes at either the enable input or the down/ up input should be made only when the clock input is high. The direction of the count is determined by the level of the down/up input. When low, the counter counts up and when high, it counts down. This counter is fully programmable; that is, the outputs may be preset to either level by placing a low on the load input and entering the desired data at the data inputs. The output will change independent of the level of the clock input. This feature allows the counters to be used as modulo-N dividers by simply modifying the count length with the preset inputs. The clock, down/up, and load inputs are buffered to lower the drive requirement; which significantly reduces the number of clock drivers, etc., required for long parallel words. Two outputs have been made available to perform the cascading function: ripple clock and maximum/minimum count. The latter output produces a high-level output pulse with a duration approximately equal to one complete cycle of the clock when the counter overflows or underflows. The ripple clock output produces a low-level output pulse equal in width to the low-level portion of the clock input when an overflow or underflow condition exists. The counters can be easily cascaded by feeding the ripple clock output to the enable input of the succeeding counter if parallel clocking is used, or to the clock input if parallel enabling is used. The maximum/minimum count output can be used to accomplish look-ahead for high-speed operation.

CD ~ G) ..- r----------------------------------------------------------------------------, ~National ~ Semiconductor DM54193 Synchronous Up/Down 4-Bit Binary Counter with Dual Clock General Description This circuit is a synchronous up/down 4-bit binary counter. Synchronous operation is provided by having all flip-flops clocked simultaneously, so that the outputs change together when so instructed by the steering logic. This mode of operation eliminates the output counting spikes normally associated with asynchronous (ripple-clock) counters. The outputs of the four master-slave flip-flops are triggered by a low-to-high level transition of either count (clock) input. The direction of counting is determined by which count input is pulsed, while the other count input is held high. This counter was deSigned to be cascaded without the need for external circuitry. Both borrow and carry outputs are available to cascade both the up and down counting functions. The borrow output produces a pulse equal in width to the count down input when the counter underflows. Similarly, the carry output produces a pulse equal in width to the count up input when an overflow condition exists. The counter can then be easily cascaded by feeding the borrow and carry outputs to the count down and count up inputs respectively of the succeeding counter. This counter is fully programmable; that is, each output may be preset to either level by entering the desired data at the inputs while the load input is low. The output will change independently of the count pulses. This feature allows the counter to be used as modulo-N divider by Simply modifying the count length with the preset inputs. • • • • Features Fully independent clear input Synchronous operation Cascading circuitry provided internally Individual preset each flip-flop A clear input has been provided which, when taken to a high level, forces all outputs to the low level; independent of the count and load inputs. The clear, count, and load inputs are buffered to lower the drive requirements of clock drivers, etc., required for long words.

The register has four distinct modes of operation, namely: Parallel (broadside) load Shift right (in the direction QA toward QD) Shift left (in the direction QD toward QA) Inhibit clock (do nothing) Synchronous parallel loading is accomplished by applying the four bits of data and taking both mode control inputs, SO and 51, high. The data is loaded into the associated flipflops and appears at the outputs after the positive transition of the clock input. During loading, serial data flow is inhibited. Shift right is accomplished synchronously with the riSing edge of the clock pulse when SO is high and 51 is low. Serial data for this mode is entered at the shift-right data input. When SO is low and 51 is high, data shifts left synchronously and new data is entered at the shift-left serial input. Clocking of the flip-flop is inhibited when both mode control inputs are low. The mode controls of the DM541941 DM74194 should be changed only while the clock input is high.

State changes are initiated by the falling edge of the clock. The '197 has a Master Reset (MR) input which overrides all other inputs and asynchronously forces all outputs LOW. A Parallel Load input (PL) overrides clocked operations and asynchronously loads the data on the Parallel Data inputs (Pn) into the flip-flops. This preset feature makes the circuit usable as a programmable counter. The circuit can also be used as a 4-bit latch, loading data from the Parallel Data inputs when PL is LOW and storing the data when PL is HIGH.

The binary sum appears on the Sum (SO-S3) and outgoing carry (C4 outputs. The binary weight of the various inputs and outputs is indicated by the subscript numbers, representing powers of two. 2 0 (AO + 80 + CO) + 21 (A1 + 81) + 22(A2 + 82) + 23 (A3 + 83) = SO + 2S1 + 4S2 + 8S3 + 16C4 Where (+) = plus Interchanging inputs of equal weight does not affect the operation. Thus CO, AO, 80 can be arbitrarily assigned to pins 5, 6 and 7. Due to the symmetry of the binary add function, the '283 can be used either with all inputs and outputs active HIGH (positive logic) or with all inputs and outputs active LOW (negative logic). Note that if CO is not used it must be tied LOW for active HIGH logic or tied HIGH for active LOW logic. Example: Due to pin limitations, the intermediate carries of the '283 are not brought out for use as inputs or outputs. However, other means can be used to effectively insert a carry into, or bring a carry out from, an intermediate stage. Rgure a shows a way of making a 3-bit adder. Tying the operand inputs of the fourth adder (A3, 83) LOW makes S3 dependent ony on, and equal to, the carry from the third adder. Using somewhat the same principle,Figure b shows a way of dividing the '283 into a 2-bit and a I-bit adder. The third stage adder (A2, 82, S2) is used merely as a means of getting a carry (Cl 0) signal into the fourth stage (via A2 and 82) and bringing out the carry from the second stage on S2. Note that as long as A2 and 82 are the same, whether HIGH or LOW, they do not infuence S2. Similarly, when A2 and 82 are the same the carry into the third stage does not influence they carry out of the third stage. Figure c shows a method of implementing a 5-input encoder, where the inputs are equally weighted. The outputs SO, SI and S2 present a binary number equal to the number of inputs 11-15 that are true. Figure d shows one method of implementing a 5-input majority gate. When three or more of the inputs 11-15 are true, the output M5 is true.

The outputs have the TRI-STATE feature. When enabled, the outputs exhibit the low impedance characteristics of a standard TTL output with additional drive capability to permit the driving of bus lines without external resistors. When disabled, both the output transistors are turned off presenting a high-impedance state to the bus line. Thus the output will act neither as a significant load nor as a driver. To minimize the possibility that two outputs will attempt to take a common bus to opposite logiC levels, the disable time is shorter than the enable time of the outputs.

Inputs for one word are 54/74 series-compatible TIL inputs, whereas those of the second word are high-impedance receivers driven by a terminated data bus. These bus inputs include 0.65V typical hysteresis which provides 1.4V noise immunity. The DM7136 has open-collector outputs which go to the high state upon equality and is expandable to n bits by coliector-ORing. The device has an output latch which is strobe controlled. The transfer of information to the output occurs when the STROBE input goes from a logic "1" to a logic "0" state. Inputs may be changed while the STROBE is at the logic "1" level, without affecting the state of the output. These devices are useful as address comparators in computer systems utilizing unified data bus organization. • • • • • Low bus input current 15 p.A typ High bus input noise immunity 1.4V typ Bus inputs comply with IEEE 488-1975 TIL-compatible output Output latch provision Connection Diagram Dual-In-Llne Package 86 T8 15 14 2 81 T1 3 82 85 T5 B4 13 4 T2 12 5 B3 T4 OUTPUT 11 10 8 7 T3 fiiiOiiE 9 J8 GND (BUS INPUT) (TTL INPUT) TL/F/6577-1 Order Number DM7136J or DM7136W See NS Package Number J16A or W16A Function Table Output Condition DM7118136 H L L °Lalched In previous sta18.

The registers have two modes of operation: parallel (broadside) load and shift (in direction OA toward 00)· Parallel loading is accomplished by applying the four bits of data and taking the shift/load control input low. The data is loaded into the associated flip-flops, and appears at the outputs after the positive transition of the clock input. During loading, serial data flow is inhibited. Shifting is accomplished synchronously when the shift/load control input is high. Serial data for this mode is entered at the JK inputs. These inputs permit the first stage to perform as a JK, D or T-type flip-flop as shown in the function table. These shift registers are fully compatible with most other TTL and DTL families. All inputs, including the clock, are buffered to lower the drive requirements to one normalized Series 54174 load.

The demultiplexing function is performed by using the 4 input lines to address the output line, passing data from one of the strobe inputs with the other strobe input low. When either strobe input is high, all outputs are high. These demultiplexers are ideally suited for implementing high-performance memory decoders. All inputs are buffered and input clamping diodes are provided to minimize transmission-line effects and thereby simplify system design. • Pin for pin with popular DM54154174154 • Decodes 4 binary-coded inputs Into one of 16 mutually exclusive outputs • Performs the demultiplexing function by distributing data from one input line to anyone of 16 outputs • Input clamping diodes simplify system design • High fan-out, low-impedance, totem-pole outputs • Typical propagation delay 19 ns • Typical power dissipation 170 mW • Alternate Military/Aerospace device (9311) is available.

When the Enable goes HIGH, data present in the latches is stored and the state of the latch is no longer affected by the Sn and On inputs. The Master Reset when activated overrides all other input conditions forcing all latch outputs LOW. Each of the four latches can be operated in one of two modes: 0-TYPE LATCH-For D-type operation the S input of a latch is held LOW. While the common Enable is active the latch output follows the 0 input. Information present at the latch output is stored in the latch when the Enable goes HIGH. SET/RESET LATCH-During set/reset operation when the common Enable is LOW a latch is reset by a LOW on the 0 input, and can be set by a LOW on the S input if the 0 input is HIGH. If both Sand 0 inputs are LOW, the 0 input will dominate and the latch will be reset. When the Enable goes HIGH, the latch remains in the last state prior to disablement. The two modes of latch operation are shown in the Truth Table.

The 9316 is a 4-bit binary counter. The carry output is decoded by means of a NOR gate, thus preventing spikes during the normal counting mode of operation. Synchronous operation is provided by having all flip-flops clocked simultaneously so that the outputs change coincident with each other when so instructed by the count-enables inputs and internal gating. This mode of operating eliminates the output counting spikes which are normally associated with asynchronous (ripple clock) counters. A buffered clock input triggers the four flip-flops on the rising (positive-going) edge of the clock input waveform. These counters are fully programmable; that is, the outputs may be preset to either level. As presetting is synchronous, setting up a low level at the load input disables the counter and causes the outputs to agree with the setup data after the next clock pulse regardless of the levels of the enable input. Low-to-high transitions at the load input are perfectly acceptable regardless of the logic levels on the clock or enable inputs. The clear function is asynchronous and a low level at the clear input sets of the flip-flop outputs low regardless of the levels of clock, load, or enable inputs. The carry look-ahead circuitry provides for cascading counters for n-bit synchronous applications without additional gating. Instrumental in accomplishing this function are two count-enable inputs and a ripple carry output. Both countenable inputs (P and T) must be high to count, and input T is fed-forward to enable the ripple carry output. The ripple carry output thus enabled will produce a high-level output pulse with a duration approximately equal to the high-level portion of the QA output. This high-level overflow ripple carry pulse can be used to enable successive cascaded stages. Highto-low level transitions at the enable P or T inputs may occur regardless of the logic level in the clock.

As evident from the logic diagram, these outputs are generated in only three gate delays. The "A equals 8" output is generated in one additional gate delay by decoding the" A neither less than nor greater than 8" condition with a NOR gate. All three outputs are activated by the active LOW Enable Input (E). Tying the A > 8 output from one device into an A input on another device and the A < 8 output into the corresponding 8 input permits easy expansion.

Thus if A4 is HIGH and 84 is LOW, the A > 8 output will be HIGH regardless of all other inputs except E.

The clocking of each register is controlled by the OR function of the separate and the common clock input. Each register is composed of eight clocked RS master/slave flip-flops and a number of gates. The clock OR gate drives the eight clock inputs of the flip-flops in parallel. When the two clock inputs (the separate and the common) to the OR gate are LOW. the slave latches are steady. but data can enter the master latches via the Rand S input. During the first LOW-to-HIGH transition of either, or both simultaneously, of the two clock inputs, the data inputs (R and S) are inhibited so that a later change in input data will not affect the master; then the now trapped information in the master is transferred to the slave. When the transfer is complete, both the master and the slave are steady as long as either or both clock inputs remain HIGH. During the HIGH-to-LOW transition of the last remaining HIGH clock input, the transfer path from master to slave is inhibited first, leaving the slave steady in its present state. The data inputs (R and S) are enabled so that new data can enter the master. Either of the clock inputs can be used as clock inhibit inputs by applying a logiC HIGH signal. Each B-bit shift register has a 2-input multiplexer in front of the serial data input. The two data inputs DO and 01 are controlled by the data select input (S) following the Boolean expression: Serial data in: So = SDO + SOl An asynchronous master reset is provided which, when activated by a LOW logic level, will clear all 16 stages independently of any other input signal.

It is a multifunctional device capable of storing single line data in eight addressable latches, and being a oneof-eight decoder and demultiplexer with active level high outputs. The device also incorporates an active level low common clear for resetting all latches, as well as an active level low enable. The DM9334 has four modes of operation which are shown in the mode selection table. In the addressable latch mode, data on the data line (D) is written into the addressed latch. The addressed latch will follow the data input with all nonaddressed latches remaining in their previous states. In the memory mode, all latches remain in their previous state and are unaffected by the data or address inputs. In the one-of-eight decoding or demultiplexing mode, the addressed output will follow the state of the D input with all other inputs in the low state. In the clear mode all outputs are low and unaffected by the address and data inputs. When operating the device as an addressable latch, changing more than one bit of the address could impose a transient wrong address. Therefore, this should only be done while in the memory mode. The function tables summarize the operation of the product.

Data can be written into anyone and read from any two of the eight locations simultaneously. Master/slave operation eliminates all race problems associated with simultaneous read/write activity from the same location. When the clock input (CP) is LOW data applied to the data input line (DA) enters the selected master. This selection is accomplished by coding the three write input select lines (AO-A2) appropriately. Data is stored synchronously with the rising edge of the clock pulse. data during the read operation. The state of each slave is determined by the state of the master selected by its associated set of read address inputs. The method of parallel expansion is shown in Figure a. One 9338 is needed for each bit of the required word length. The read and write input lines should be connected in common on all of the devices. This register configuration provides two words of n-bits each at one time, where n devices are connected in parallel. logic Symbol The information for each of the two slaved (output) latches is selected by two sets of read address inputs (BO-B2 and CO-C2). The information enters the slave while the clock is HIGH and is stored while the clock is LOW. If Slave Enable is LOW (SLE), the slave latches are continuously enabled. The signals are available on the output pins (ZB and Zc). The input bit selection and the two output bit selections can be accomplished independently or simultaneously. The data flows into the device, is demultiplexed according to the state of the write address lines and is clocked into the selected latch. The eight latches function as masters and store the input data. The two output latches are slaves and hold the 'i Y I Iii I i It AO AI A2 BO BI B2 CO CI C2 12- DA 11- CP 10-(l SLE Ib Ie 1 !

The '68 drives any common cathode LED display rated at a nominal 20 mA at 1.7Y per segment without need for current limiting resistors. This device accepts a 4-bit binary code and produces output drive to the appropriate segments of the 7-segment display. It has a hexadecimal decode format which produces numerIc codes "0" thru "9" and alpha codes "A" through "F" using upper and lower case fonts. Latches on the four data inputs are controlled by an active LOW latch enable LE. When the LE is LOW, the state of the outputs is determined by the input data. When the LE goes HIGH, the last data present at the inputs is stored in the latches and the outputs remain stable. The LE pulse width necessary to accept and store data is typically 30 ns which allows data to be strobed into the '68 at normal TTL speeds. This feature means that data can be routed directly from high speed counters and frequency dividers into the display without slowing down the system clock or providing intermediate data storage. Another feature of the '68 is that the unit loading on the data inputs is very low (-100 IJ.A Max) when the latch enable is HIGH. This allows '68s to be driven from an MOS device in multiplex mode without the need for drivers on the data lines. The '68 also has provision for automatic blanking of the leading and/or trailing edge zeros in a multidigit decimal number, resulting In an easily readable decimal display conforming to normal writing practice. In an eight digit mixed integer fraction decimal representation, using the automatic blanking capability, 0060.0300 would be displayed as 60.03. Leading edge zero suppression is obtained by connecting the Ripple Blanking Output (RBO) of a decoder to the Ripple Blanking Input (RBI) of the next lower stage device. The most significant decoder stage should have the RBI input grounded; and since suppression of the least significant integer zero in a number is not usually desired, the RBI input of this decoder stage should be left open. A similar procedure for the fractional part of a display will provide automatic suppression of trailing edge zeros. The RBO terminal of the decoder can be OR-tied with a modulating signal via an isolating buffer to achieve pulse duration intensity modulation. A suitable signal can be generated for this purpose by forming a variable frequency multivibrator with a cross coupled pair of TTL or DTL gates.

It may also be used to drive common anode LED displays, multiplexed or directly with the aid of suitable current limiting resistors. This device accepts a 4-blt binary code and produces output drive to the appropriate segments of the 7-segment display. It has a hexadecimal decode format which produces numerIc codes "0" through "9" and alpha codes "A" through "F" using upper and lower case fonts. Latches on the four data Inputs are controlled by an active LOW latch enable LE. When the LE Is LOW, the state of the outputs Is determined by the Input data. When the LE goes HIGH, the last data present at the Inputs Is stored In the latches and the outputs remain stable. The LE pulse width necessary to accept and store data is typically 30 ns which allows data to be strobed Into the '70 at normal TTL speeds. This feature means that data can be routed direclly from high speed counters and frequency dividers Into the display without slowing down the system clock or providing intermediate data storage. The latch/decoder combination Is a'sir'!'lple system which drives Incandescent displays with multiplexed data Inputs from MOS time clocks, DVMs, calculator chips, etc. Data Inputs are multiplexed while the displays are In static mode. This lowers component and insertion costs since several circuits-seven diodes per display, strobe drivers, a sepa- rate display voltage source, and clock failure detect circuits-traditionally found in incandescent multiplexed display systems are eliminated. It also allows low strobing rates to be used without display flicker. Another '70 feature is the reduced loading on the data inputs when the Latch Enable is HIGH (only 10 p.A typ). This allows many '70s to be driven from a MOS device in multiplex mode without the need for drivers on the data lines. The '70 also provides automatic blanking of the leading and/or trailing-edge zeroes in a multidigit decimal number, resulting in an easily readable decimal display conforming to normal writing practice. In an B-digit mixed integer fraction decimal representation, using the automatic blanking capability, 0060.0300 would be displayed as 60.03. Leadlngedge zero suppression Is obtained by connecting the Ripple Blanking Output (RBO) of a decoder to the Ripple Blanking Input (RBI of the next lower stage device.

First, examine the power used in the normal display driving method where the display and decoder driver are both operated from a + 5.0V regulated supply (Vee = Vs). can maintain approximately 15 mA with as little as 0.5V across the output device. By using a separate power source (Vs, Figure C) for the LEOs, which is set to the LED VF plus the offset voltage of the driver, as much as 280 mW can be saved per digit. i.e., Vs = VF (Max) + Vollset = 2.0V + O.5V = 2.5V PT = 2.5V x 14 mA (from Figure B) x 7 = 245 mW The power dissipated by the LED and the driver outputs is (Vee x Iseg x n Segments). The total power dissipated with a 15 mA LED displaying an eight (8) would be: These figures show that using a separate supply to drive the LEOs can offer significant display power savings. In battery powered equipment, two rechargeable nickle-cadmium cells in series would be sufficient to drive the display, while four such cells would be needed to operate the logic units. PTOT = 5.0V x 15 mA x 7 = 525 mW Of this 525 mW, the power actually required to drive the LED is dependent on the VF drop of each segment. Most GaAsP LEDs exhibit either a 1.7V or a 3.4V forward voltage drop. Therefore, the required total power for seven segments would be: Another method to save power is to apply intensity modulation to the displays (Figure DJ. It is well known that LED displays are more efficient when operated in pulse mode. There are two reasons: one, the quantum efficiency of the LED material is better; secondly the eye tends to peak detect. Typically a 20% off duty cycle to displays (GaAsP) will produce the same brightness as operating under dc conditions. P(1.7) = 1.7V x 15 mA x 7 = 178.5 mW P(3.4) = 3.4V x 15 mA x 7 = 357 mW The remaining power is dissipated by the driver outputs which are maintaining the 15 mA constant current required by the LEOs. Most of this power is wasted, since the driver Vs COMMON ANODE LED vee .., " " CURRENT FLOW ~ TUF/l0210-11 FIGURE C_ Separate Supply for LED Displays 4-331 ~ G) Applications (Continued) LEAST SIGNIFICANT DECADE AI A2 A4 AB - - - ---------- Cl C2 C4 C8 - - - ---------- - - - ---------.

Intensity Control by RBO Pulse Duty Cycle Therefore, the removal of a large portion of the filtered dc current requirement (display power) substantially reduces the transformer loading. There are two basic approaches. First (Figure E) is the direct full wave rectified unregulated supply to power the displays. The '74 decoder driver constant current feature maintains the specified segment current after the LED diode drop and 0.5V saturation voltage has been reached ("'2.2V). Care must be exercised not to exceed the '74 power ratings and the maximum voltage that the decoder driver sees in both the "on" and "off" modes. The second approach (Figure F) uses a 3-terminal voltage regulator such as the 7805 to provide dc pulsed power to the display with the peak dc voltage limited to +5.0V. This approach allows easier system thermal management by heat sinking the regulator rather than the display or display drivers. When this power source is used with an intensity modulation scheme or with a multiplexed display system, the frequencies must be chosen such that they do not beat with the 120 Hz full wave rectified power frequency. Low Power, Low Cost Display Power Sources-In small line operated systems using TTL/MSI and LED or incandes· cent displays, a significant portion of the total dc power is consumed to drive the displays. Since it is irrelevant whether displays are driven from unfiltered dc or pulsed dc (at fast rates), a dual power system can be used that makes better utilization of transformer rms ratings. The system utilizes a full wave rectified but unsmoothed dc voltage to provide the displays with 120 Hz pulsed power while the reset of the system is driven by a conventional dc power circuit. The frequency of 120 Hz is high enough to avoid display flicker problems. The main advantages of this system are: • Reduced transformer rating • Much smaller smoothing capaCitor • Increased LED light output due to pulsed operation With the standard capacitor filter circuit, the rms current (full wave) loading of the transformer is approximately twice the dc output. Most commercial transformer manufacturers rate transformers with capacitive input filters as follows: Full Wave Bridge Rectifier Circuit Transformer rms current = 1.8 x dc current required Full Wave Center Tapped Rectifier Circuit Transformer rms current = 1.2 x dc current required 4-332 r-------------------------------------------------------------------------------------~ U) Co) Applications ~ (Continued) Vs UNREGULATED FULL WAVE\ RECTIFIED DISPLAY VOLTAGE _ " VCC=5V~r__;:::t::;_--_r--;:::t::;----~ FOR LOGIC COMMON ANODE LED 1~11 6:1 TL/F/l0210-7 FIGURE E.

This allows the designer to employ either leading-edge or trailing-edge triggering, which is independent of input transition times. When input conditions for triggering are met, a new cycle starts and the external capacitor is allowed to rapidly discharge and then charge again. The retriggerable feature permits output pulse widths to be extended. In fact a continuous true output can be maintained by having an input cycle time which is shorter than the output cycle time. The output pulse may then be terminated at any time by applying a low logic level to the RESET pin. Retriggering may be inhibited by either connecting the Q output to an active high input, or the Q output to an active low input. • • • • • • 70 ns to co output width range Resettable and retriggerable--O% to 100% duty cycle TTL input gating-leading or trailing edge triggering Complementary TTL outputs Optional retrigger lock-out capability Pulse width compensated for Vee and temperature variations • Alternate Military/Aerospace device (54xxx) is available.

Multiple J and K inputs are AN Oed together to produce the internal J and K function for the flip-flop. The J and K data is processed by the flip-flop after a complete clock pulse. While the clock is low the slave is isolated from the master. On the positive transition of the clock, the data from the AND gates is transferred to the master. While the clock is high the AND gate inputs are disabled. On the negative transition of the clock the data from the master is transferred to the slave. The logic state of the J and K inputs must not be allowed to change while the clock is in the high state. Data is transferred to the outputs on the falling edge of the clock pulse. A low logic level on the preset or clear inputs sets or resets the outputs regardless of the logic levels of the other inputs.

The clock input may be applied simultaneously to clock 1 and clock 2 if both modes can be clocked from the same source. Changes at the mode control input should normally be made while both clock inputs are low; however, conditions described in the last three lines of the truth table will also ensure that register contents are protected. These 4-bit registers feature parallel and serial inputs, parallel output, mode control, and two clock inputs. The registers have three modes of operation. Parallel (broadside) load Shift right (the direction OA toward OD) Shift left (the direction OD toward 0A) Parallel loading is accomplished by applying the four bits of data and taking the mode control input high. The data is loaded into the associated flip-flops and appears at the outputs after the high-to-Iow transition of the clock-2 input. During loading, the entry of serial data is inhibited. Shift right is accomplished on the high-to-Iow transition of clock 1 when the mode control is low; shift left is accomplished on the high-ta-Iow transition of clock 2 when the Features • Typical maximum clock frequency 14 MHz • Typical power dissipation mW Connection Diagram Dual-In-Line Package OUTPUTS OUTPUTS ...----.-...

The data on the parallel inputs PO-P3 is transferred to the respective 00-03 outputs following the lOW-to-HIGH clock transition. Shift left operation (03 - 02) can be achieved by tying the an outputs to the Pn-1 inputs and holding the PE input lOW. All serial and parallel data transfers are synchronous, occuring after each lOW-ta-HIGH clock transition. Since the 93100 utilizes edge triggering, there is no restriction on the activity of the J, K, Pn and PE inputs for logic operation-except for the setup and release time requirements. A lOW on the asynchronous Master Reset (MR) input sets all 0 outputs lOW, independent of any other input condition. The logic Diagrams and Truth Table indicate the functional characteristics of the 93100 4-bit shift register. The device is useful in a wide variety of shifting, counting and storage applications. It performs serial, parallel, serial-to-parallel, or parallel-to-serial data transfers. The 93100 has two primary modes of operation, shift right (00 - 01) and parallel load, which are controlled by the state of the Parallel Enable (PE) input. When the PE input is HIGH, serial data enters the first flip-flop 00 via the J and K inputs and is shifted one bit in the direction 00 - 01 - 02 - 03 following each lOW-to-HIGH clock transition.

From state 9 (HLLH) it increments to state 0 (LLLL). The 93L 16 counts modulo-16 in binary sequence. From state 15 (HHHH) it increments to state 0 (LLLL). The clock inputs of all flip-flops are driven in parallel through a clock buffer. Thus all changes of the Q outputs (except due to Master Reset) occur as a result of, and synchronous with, the LOWto-HIGH transition of the CP input signal. The circuits have four fundamental modes of operation, in order of precedence: asynchronous reset, parallel load, count-up and hold. Four control inputs-Master Reset (MRI, Parallel Enable (PE), Count Enable Parallel (CEP) and Count Enable Trickle (CEn-determine the mode of operation, as shown in the Mode Select Table. A LOW Signal on MR overrides all other inputs and asynchronously forces all outputs LOW. A LOW signal on PE overrides counting and allows information on the Parallel Data (Pn) inputs to be loaded into the flip-flops on the next rising edge of CPo With PE and MR HIGH, CEP and CET permit counting when both are HIGH. Conversely, a LOW signal on either CEP or CET inhibits counting. The 93L10 and 93L16 contain masterslave flip-flops which are "next-state catching" because of the JK feedback. This means that when CP is LOW, information that would change the state of a flip-flop, whether from the counting logic or the parallel entry logiC if either mode is momentarily enabled, enters the master and is locked in. Thus to avoid inadvertently changing the state of a master latch, and the subsequent transfer of the erroneous information to the slave when the clock rises, it is necessary to insure that neither the counting mode, nor the parallel entry mode is momentarily enabled while CP is LOW. spikes due to internal race conditions and is therefore not recommended for use as a clock or asynchronous reset for flip-flops, counters or registers. If a decade counter is preset to an illegal state, or assumes an illegal state when power is applied, it will return to the normal sequence within two counts, as shown in the state diagrams. .-....w o • w ..... U) en MULTISTAGE COUNTING The '10/'16 counters may be cascaded to provide multistage synchronous counting. Two methods commonly used to cascade these counters are shown in Figures 8 and b. In multistage counting, all less significant stages must be at their terminal count before the next more significant counter is enabled. The '10/'16 internally decodes the terminal count condition and "AN Os" it with the CET input to generate the terminal count (TC) output. This arrangement allows one to perform series enabling by connecting the TC output (enable signal) to the CET input of the following stage, Figure 8. The setup requires very few interconnections, but has the following drawback: since it takes time for the enable to ripple through the counter stages, there is a reduction in maximum counting speed. To increase the counting rate, it is necessary to decrease the propagation delay of the TC signal, which is done in the second method. The scheme illustrated in Figure b permits multistage counting, limited by the fan-out of the terminal count. The CEP input of the '10/'16 is internally "ANDed" with the CET input and as a result, both must be HIGH for the counter to be enabled. The CET inputs are connected as before except for the second stage. There the CET input is left floating and is therefore HIGH. Also, all CEP inputs are connected to the terminal output of the first stage. The advantage of this method is best seen by assuming all stages except the second and last are in their terminal condition. As the second stage advances to its terminal count, an enable is allowed to trickle down to the last counter stage, but has the full cycle time of the first counter to reach it. Then as the TC of the first stage goes active (HIGH), all CEP inputs are activated, allowing all stages to count on the next clock. The Terminal Count (TC) output is HIGH when CET is HIGH and the counter is in its maximum count state (9 for the decade counters, 15 for the binary counters-fully decoded in both types). To implement synchronous multistage counters, the TC outputs can be used with the CEP and CET inputs in two different ways. These two schemes are shown in Figures 8 and b.

When the Enable goes HIGH, data present in the latches is stored and the state of the latch is no longer affected by the Sn and Dn inputs. The Master Reset when activated over· rides all other input conditions forcing all latch outputs LOW. Each of the four latches can be operated in one of two modes: O·TYPE·LATCH-For O·type operation the S input of a latch is held LOW. While the common Enable is active the latch output follows the 0 input. Information present at the latch output Is stored in the latch when the Enable goes HIGH. SET/RESET LATCH-During set/reset operation when the common Enable is LOW a latch is reset by a LOW on the 0 input, and can be set by a LOW on the S input if the D input is HIGH. If both Sand D inputs are LOW, the D input will dominate and the latch wi! be reset. When the Enable goes HIGH, the latch remains in the last state prior to disable· ment. The two modes of latch operation are shown in the Truth Table.

The clocking of each register is controlled by the OR function of the separate and the common clock input. Each register is composed of eight clocked RS master/slave flip-flops and a number of gates. The clock OR gate drives the eight clock inputs of the flip-flops in parallel. When the two clock inputs (the separate and the common) to the OR gate are LOW, the slave latches are steady, but data can enter the master latches via the Rand S input. During the first LOW-to-HIGH transition of either, or both simultaneously, of the two clock inputs, the data inputs (R and S) are inhibited so that a later change in input data will not affect the master; then the now trapped information in the master is transferred to the slave. When the transfer is complete, both the master and the slave are steady as long as either or both clock inputs remain HIGH. During the HIGH-to-LOW transition of the last remaining HIGH clock input, the transfer path from master to slave is inhibited first, leaving the slave steady in its present state. The data inputs (R and S) are enabled so that new data can enter the master. Either of the clock inputs can be used as clock inhibit inputs by applying a logic HIGH signal. Each 8-bit shift register has a 2-input multiplexer in front of the serial data input.

In the addressable latch mode, data on the data line (D) is written into the addressed latch. The addressed latch will follow the Data input with all non-addressed latches remaining in their previous states. In the memory mode, all latches remain in their previous state and are unaffected by the data or address inputs. To eliminate the possibility of entering erroneous data into the latches, the Enable should be held HIGH while the Address lines are changing. In the 1-of-8 decoding or demultiplexing mode, the addressed output will follow the state of the D input with all other outputs in the LOW state. In the clear mode all outputs are LOW and unaffected by the address and data inputs. When operating the 93L34 as an addressable latch, changing more than one bit of the address could impose a transient wrong address. Therefore, this should only be done while in the memory mode.
