INTRODUCTION
The high-speed silicon-gate CMOS (HCMOS) logic family from Texas Instruments offers a broad range of functions
from basic gates and flip-flops to bus-compatible complex devices. The devices in this family are pin-for-pin
and functionally compatible with the corresponding devices in the popular LSTTL family while offering a significant
power savings. Both CMOS voltage-compatible functions, SN54174HC', and TTL voltage-compatible functions,
SN54/74HCr are included in Tl's HCMOS logic family.
The HCMOS logic devices included in this book offer speed and drive capability comparable to LS but with lower
power dissipation for applications where power must be minimized. The availability of these devices in surface
mount packaging, both SO and LCC, also makes them especially attractive for use in systems where board
space is critical.
High-speeds and low power consumption have been made possible by the 3-",m self-aligned poly-silicon-gate
CMOS process. This self-aligning process permits smaller channel lengths, hence an increase in switching speeds
and less gate capacitance.
Through the successful execution of an aggressive design-in reliability program, Texas Instruments is able to
offer a HCMOS logic family with reliability consistent with that of more mature technologies. Reliability
improvement programs are ongoing. Further, a quality watch program to continually monitor the quality and
reliability of production devices is in place and guarantees a consistent product of the highest quality.
This book contains pertinent technical information on available HCMOS devices. The general information section
includes a functional and numerical index, and parameter measurement information. The mechanical section
provides packaging information on all devices included in this book. A detailed discussion of interchangeability,
electrostatic discharge (ESD) protection, latch-up circuitry, design considerations, interfacing, and other pertinent
subjects regarding this family can be found in the designer's information section.
Complete technical data for any Texas Instruments semiconductor/component product is available from your
nearest TI field sales office, local authorized TI distributor, or by writing direct to:
Texas Instruments Incorporated
P.O. Box 809066
Dallas, TX 75244-9066
We sincerely hope that you will find the new HCMOS Logic Data Book a meaningful addition to your technical
library.

ATTENTION

These devices contain circuits to protect the inputs and outputs
against damage due to high static voltages or electrostatic fields.
however. it is advised that precautions be taken to avoid application
of any voltage higher than maximum-rated voltages to these highimpedance circuits.
Unused inputs must always be connected to an appropriate logic
voltage level. preferably either Vee or ground.

D FLlp·FlOP AND LATCH SIGNAL CONVENTIONS

D flip·flop and latch signal conventions

-:::::I
....

..

It is normal TI practice to name the outputs and other inputs of a O-type flip-flop or latch and to draw
its logic symbol based on the assumption of true data (0) inputs. Outputs that produce data in phase with
the data inputs are called 0 and those producing complementary data are called O. An input that causes
a 0 output to go high or a 0 output to go low is called Preset (PRE). An input that causes a 0 output to
go high or a 0 output to go low is called Clear (CLR). Bars are used over these pin names (PRE and CLR)
if they are active-low.

o
3

The devices on several data sheets are second-source designs, and the pin-name conventions used by
the original manufacturers have been retained. That makes it necessary to designate the inputs and outputs
of the inverting circuits 0 and O.

r+

In some applications, it may be advantageous to redesignate the data input from 0 to 0 or vice versa.
In that case, all the other inputs and outputs should be renamed as shown below. Also shown are
corresponding changes in the graphical symbols. Arbitrary pin numbers are shown in parentheses.

The figures show that when 0 and 0 exchange names, the Preset and Clear pins also exchange names.
The polarity indicators (t::..) on PRE and CLR remain, as these inputs are still active-low, but the presence
or absence of the polarity indicator changes at 0 (or 0). 0, and O. Pin 5 (0 or 0) is still in phase with
the data input (0 or 0); their active levels change together.

each output changes to the complement of its previous level on each active transition indicated by
~ or t.

If, in the input columns, a row contains only the symbols H, L, and/or X, this means the indicated output is valid whenever the input configuration is achieved and regardless of the sequence in which it is achieved. The output persists so
long as the input configuration is maintained.
If, in the input columns, a row contains H, L, and/or X together with t and/or t this means the output is valid whenever the input configuration is achieved but the transition(s) must occur following the achievement of the steady-state
levels. If the output is shown as a level (H, L, 00, or 00), it persists so long as the steady-state input levels and the
levels that terminate indicated transitions are maintained. Unless otherwise indicated, input transitions in the opposite
direction to those shown have no effect at the output. (If the output is shown as a pulse,rLor LS,the pulse
follows the indicated input transition and persists for an interval dependent on the circuit.)

The first line of the table represents a synchronous clearing of the register and says that if clear is low, all four outputs
will be reset low regardless of the other inputs. In the following lines, clear is inactive (high) and so has no effect.
The second line shows that so long as the clock input remains low (while clear is high), no other input has any effect
and the outputs maintain the levels they assumed before the steady·state combination of clear high and clock low was
established. Since on other lines of the table only the rising transition of the clock is shown to be active, the second line
implicitly shows that no further change in the outputs will occur while the clock remains high or on the high·to·low
transition of the clock.
The third line of the table represents synchronous parallel loading of the register and says that if Sl and SO are both
high then, without regard to the serial input, the data entered at A will be at output 0A, data entered at B will be at
0B, and so forth, following a low·to·high clock transition.
The fourth and fifth lines represent the loading of high· and low·level data, respectively, from the shift·right serial input
and the shifting of previously entered data one bit; data previously at 0A is now at OB, the previous I.evels of 0B and
Oc are now at Oc and OD respectively, and the data previously at OD is no longer in the register. This entry of serial
data and shift takes place on the low·to·high transition of the clock when Sl is low and SO is high and the levels at
inputs A through D have no effect.
The sixth and seventh lines represent the loading of high· and low·level data, respectively, from the shift·left serial input
and the shifting of previously entered data one bit; data previously at OB is now at OA, the previous levels of Oc and
OD are now at OB and OC, respectively, and the data previously at OA is no longer in the register. This entry of serial
data and shift takes place on the low·to·high transition of the clock when Sl is high and SO is low and the levels at
inputs A through D have no effect.
The last line shows that as long as both mode inputs are low, no other input has any effect and, as in the second line,
the outputs maintain the levels they assumed before the steady-state combination of clear high and both mode inputs
low was established.
The function table functional tests do not reflect all possible combinations or sequential modes.

The time interval between two reference points (10% and 90% unless otherwise specified) on a waveform
that is changing from the defined low level to the defined high level (rise time) or from the defined high level
to the defined low level (fall time).
tw

Pulse duration (width)
The time interval between specified reference points on the leading and trailing edges of the pulse waveform.

VIH

High-level input voltage
An input voltage within the more positive (less negative) of the two ranges of values used to represent the
binary variables.
NOTE: A minimum is specified that is the least-positive value of high-level input voltage for which operation
of the logic element within specification limits is guaranteed.

VIL

Low-level input voltage
An input voltage level within the less positive (more negative) of the two ranges of values used to represent
the binary variables.
NOTE: A maximum is specified that is the most-positive value of low-level input voltage for which operation
of the logic element within specification limits is guaranteed.

VOH

High-level output voltage
The voltage at an output terminal with input conditions applied that, according to product specification, will
establish a high level at the output.

VOL

Low-level output voltage
The voltage at an output terminal with input conditions applied that, according to product specification, will
establish a low level at the output.

VT +

Positive-going threshold level
The voltage level at a transition-operated input that causes operation of the logic element according to
specification as the input voltage rises from a level below the negative-going threshold voltage, VT _.

VT _

Negative-going threshold level
The voltage level at a transition-operated input that causes operation of the logic element according to
specification as the input voltage falls from a level above the positive-going threshold voltage, VT + .

description
These devices contain four independent 2-input
NAND gates. They perform the Boolean
functions Y = A· B or Y = Ii. + B in positive logic.
The open-drain outputs require pull-up resistors
to perform correctly. They may be connected to
other open-drain outputs to implement activelow wired-OR or active-high wired-AND
functions.

description
These devices contain four independent 2-input
NAND gates, They perform the Boolean
functions Y = A· B or Y = Po: +B in positive logic.
The open-drain outputs require pull-up resistors
to perform correctly, They may be connected to
other open-drain outputs to implement activelow wired-OR or active-high wired-AND
functions.

description
These devices contain two independent J-K
negative-edge-triggered flip-flops. A low level at
the Clear input resets the outputs regardless of
the other inputs. When Clear is inactive (high),
data at the J and K inputs meeting the setup time
requirements are transferred to the outputs on
the negative-going edge of the clock pulse.
Following the hold time interval, data at the J and
K inputs may be changed without affecting the
levels at the outputs. These flip-flops can also
perform as toggle flip-flops by tying J and K high.
The SN54HC73 is characterized for operation
over the full military temperature range of
- 55°C to 125°C. The SN74HC73 is
characterized for operation from - 40°C to
85°C.

description
These devices contain two independent Ootype
pDsitive-edge-triggered flip-flops. A low level at
the Preset or Clear inputs sets or resets the
outputs regardless of the levels of the other
inputs. When Preset and Clear are inactive
(high), data at the 0 input meeting the setup time
requirements are transferred to the outputs on
the positive-going edge of the clock pulse. Clock
triggering occurs at a voltage level and is not
directly related to the rise time of the clock pulse.
Following the hold time interval, data at the 0
input may be changed without affecting the
levels at the outputs.

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 Q output when the
enable (C) is high, and the Q output will follow
the data input as long as the enable remains high.
When the enable goes low, the information.
which was present at the data input at the time
the transition occurred. is retained at the Q
output until the enable is permitted to go high.
The SN54HC75 is characterized for operation
over the full military temperature range of
- 55
to 125
The SN74HC75 is
characterized for operation from -40°C to
85°C.

description
These devices contain two independent J-K
negative-edge-triggered flip-flops. A low level at
the Preset or Clear input sets or resets the
outputs regardless of the levels of the other
inputs, When Preset and Clear are inactive
(high), data at the J and K inputs meeting the
setup time requirements are transferred to the
outputs on the negative-going edge of the clock
pulse, Clock triggering occurs at a voltage level
and is not directly related to the rise time of the
clock pulse, Following the hold time interval,
data at the J and K inputs may be changed
without affecting the levels at the outputs,
These versatile flip-flops can also perform as
toggle flip-flops by tying J and K high,

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 Q output when the
enable (C) is high, and the Q output will follow
the data input as long as the enable remains high.
When the enable goes low, the information,
which was present at the data input at the time
the transition occurred, is retained at the Q
output until the enable is permitted to go high.

Not available in chip carrier package
with JEDEC·Standard pinout. For chip
carrier information, contact the factory.

description
These devices contain two independent J-K
negative-edge-triggered flip-flops. A low level at
the Preset or Clear inputs sets or resets the
outputs regardless of the levels of the other
inputs. When the Preset and Clear are inactive
(high). data at the J and K inputs meeting the
setup time requirements are transferred to the
outputs on the negative-going edge of the clock
pulse. Clock triggering occurs at a voltage level
and is not directly related to the rise time of the
clock pulse. Following the hold time interval.
data at the J and K inputs may be changed
without affecting the levels at the outputs.
These versatile flip-flops can perform as toggle
flip-flops by tying J and K high.

description
These four-bit magnitude comparators perform
comparison of straight binary and straight BCD
(8-4-2-1) codes. Three fully decoded decisions
about two 4-bit words (P, Q) 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 P>Q. P Q.
P < Q, and P = 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 P = Q input. The cascading
path of the 'HC85A is implemented with only a
two-gate-Ievel delay to reduce overall
comparison times for long words.
The SN54HC85A is characterized for operation
over the full military temperature range of
- 55°C to 125°C. The SN74HC85A is
characterized for operation from - 40°C to
85°C.

description
These devices contain two independent J-K
negative-edge-triggered flip-flops. A low level at
the CLR input resets the outputs regardless of
the levels of the other inputs. When CLR is
inactive (high!, data at the J and K inputs
meeting the setup time requirements are
transferred to the outputs on the negative-going
edge of the clock pulse. Clock triggering occurs
at a voltage level and is not directly related to
the rise time of the clock pulse. Following the
hold time interval, data at the J and K inputs may
be changed without affecting the levels at the
outputs. These versatile flip-flops can perform
as toggle flip-flops by tying J and K high.

description
These devices contain two independent J-j(
negative-edge-triggered flip-flops. A low level at
the Preset or clear inputs sets or resets the
outputs regardless of the levels of the other
inputs. When Preset and Clear are inactive
(high), data at the J and j( inputs meeting the
setup time requirements are transferred to the
outputs on the positive-going edge of the clock
pulse. Clock triggering occurs at a voltage level
and is not directly related to the rise time of the
clock pulse. Following the hold time interval,
data at the J and K inputs may be changed
without affecting the levels at the outputs.
These versatile flip-flops can perform as toggle
flip-flops by grounding j( and tying J high. They
also can perform as D-type flip-flops if J and j(
are tied together.
The SN54HC 109 is characterized for operation
over the full military temperature range of
-55°C to 125°C. The SN74HC109 is
characterized for operation from - 40°C to
85°C.

description
These devices contain two independent J-K
negative-edge-triggered flip-flops. A low level at
the Preset input sets the outputs regardless of
the levels of the other inputs. When Preset (PRE)
is inactive (high), data at the J and K inputs
meeting the setup time requirements are
transferred to the outputs on the negative-going
edge of the clock pulse. Clock triggering occurs
at a voltage level and is not directly related to
the rise time of the clock pulse. Following the
hold time interval, data at the J and K inputs may
be changed without affecting the outputs. These
versatile flip-flops can perform as toggle flipflops by tying J and K high.

These bus buffers feature independent line
drivers with three-state outputs. Each 'HC125
output is disabled when the associated G is high,
and each 'HC 126 output is disabled when the
associated G is low.
The SN54HC125 and SN54HC126 are
characterized for operation over the full military
temperature range of - 55°C to 125°C. The
SN74HC125 and SN74HC126 are characterized
for operation from -40°C to 85°C,

description
The 'HC137 is a three-line tD eight-line
decoder/demultiplexer with latches Dn the three
address inputs. When the latch-enable input (GL)
is low, the 'HC137 acts as a decoder/
demultiplexer. When GL goes from low to high,
the address present at the select inputs (A, B,
and C) is stored in the latches. Further address
changes are ignored as long as GL remains high.
The output enable controls, G1 and (32, control
the outputs independently of the select or latchenable inputs, All of the outputs are forced high
if G1 is low or (32 is high. The 'HC 137 is ideally
suited for implementing glitch-free decoders in
strobed (stored-address) applications in busoriented systems,
The SN54HC 137 is characterized for operation
over the full military temperature range of
-55°C to 125°C. The SN74HC137 is
characterized for operation from -40°C to
85°C,

to high, the address present at the select inputs
(A, B, and C) is stored in the latches. Further
address changes are ignored as long as GL
remains high. The output enable controls, G1
and G2, control the outputs independently of the
select or latch-enable inputs. All of the outputs
are forced high if G 1 is low or G2 is high. The
'HCT137 is ideally suited for implementing
glitch-free decoders in strobed (stored-address)
applications in bus-oriented systems.

description
The 'HC138 circuit is designed to be used in
high-performance memory-decoding or datarouting applications requiring very short
propagation delay times. In high-performance
memory systems this decoder can be used to
minimize the effects of system decoding. When
employed with high-speed memories utilizing a
fast enable circuit, the delay times of this
decoder and the enable time of the memory 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 conditions at the binary select inputs at the
three enable inputs select one of eight input
lines. 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 without external inverters and
a 32-line decoder requires only one inverter. An
enable input can be used as a data input for
demultiplexing applications.

description
The 'HC 139 circuit is designed to be used in
high-performance memory-decoding or datarouting applications requiring very short
propagation delay times. In high-performance
memory systems, this decoder can be used to
minimize the effects of system decoding. When
employed with high-speed memories utilizing a
fast enable circuit, the delay times of this
decoder and the enable time of the memory 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 'HC139 is comprised of two individual twoline to four-line decoders in a single package. The
active-low enable input can be used as a data
line in de multiplexing applications. These
decoders/demultiplexers feature fully buffered
inputs, each of which represents only one
normalized load to its driving circuit.
The SN54HC139 is characterized for operation
over the full military temperature range of
-55°C to 125 DC. The SN74HC139 is
characterized for operation from - 40 DC to
85°C.

PRIORITY ENCODER FOR 16 BITS

Since the 'HC147 and 'HC148 are combinational logic circuits, wrong addresses can appear during input
transients. Moreover, for the 'HC148, a change from high to low at input EI can cause a transient low
on the GS output when all inputs are high. This must be considered when strobing the outputs.

description
Each of these monolithic. 4-line to 16-line
decoders decodes four binary-coded inputs into
one of sixteen mutually exclusive outputs when
both the strobe inputs. G 1 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.
The SN54HC154 is characterized for operation
over the full military temperature range of
-55°C to 125°C. The SN74HC154 is
characterized for operation from - 40°C to
85°C.

UU2>eI:

These synchronous. presettable counters feature
an internal carry look-ahead for application in
high-speed counting designs. The 'HC160 and
'HC162 are decade counters, and the 'HC16l
and 'HC163 are 4-bit binary counters.
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-enable inputs and
internal gating. This mode of operation
eliminates the output counting spikes that are
normally associated with synchronous (ripple
clock) counters. A buffered clock input triggers
the four flip-flops on the rising (positive-going)
edge of the clock input waveform.

SYNCHRONOUS 4·BIT DECADE AND BINARY COUNTERS
The application circuit shown on the preceding page is not valid for clock frequencies above 18 MHz (at 25 °C
and 4.5 V VCC). The reason for this is that there is a "glitch" that is produced on the second stage's RCa
output and every succeeding stage's RCa output. This glitch is common to all HC vendors that Texas Instruments
has evaluated in addition to the bipolar equivalents ('lS, 'AlS, 'AS).
The glitch on RCa is caused because the propagation delay of the rising edge of OA of the second stage is
shorter than the propagation delay of the falling edge of ENT. The RCa output is the product of ENT, OA, OS,
OC, and OD (ENT.OA·OB·OC·OD). The resulting glitch is about 7-12 ns in duration. Figure 1 illustrates the
condition in which the glitch occurs. For the purposes of simplicity, only two stages are being considered, but
the results can be applied to other stages. OS, OC, and OD of the first and second stage are at logic one, and
OA of both stages are at logic zero (1110 1110) after the first clock pulse. On the rising edge of the second
clock pulse, OA and RCa of the first stage will go high. On the rising edge of the third clock pulse OA and
RCa of the first stage will return to a low level, and OA of the second stage will go to a high level. It is at
this time that the glitch on the RCa of the second stage will appear because of the "race condition" inside
the chip.
The glitch will cause a problem in the next stage (stage three) if the glitch is still present when the next riSing
clock edge appears (clock pulse 4). To ensure that this does not happen, the clock frequency must be less than
inverse of the sum of the clock-to-RCO propagation delay and the glitch duration (tg)' In other words,
f max = 1/(tpd ClK-to-RCO + tg)' For example, at 25°C at 4.5 V VCC, the clock-to-RCO propagation delay
is 43 ns and the maximum duration of the glitch is 12 ns. Therefore, the maximum clock frequency that the
cascaded counters can use is 18 MHz. The following table contains the fclock, t w , and f max specifications
for applications that use more than two 'HC160 family devices cascaded together.

These 8·bit shift registers feature AND·gated
serial inputs and an asynchronous Clear. The
gated serial inputs (A and B) permit complete
control over incoming data as a low at either
input inhibits entry of the new data and resets
the first flip·flop to the low level at the next clock
pulse. A high·level 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, provided
the minimum setup time requirements are met.
Clocking occurs on the low-to-high-Ievel
transition of the clock input.
The SN54HC 164 is characterized for operation
over the full military temperature range of
-55°C to 125°C. The SN74HC164 is
characterized for operation from - 40°C to
85°C.

J:

The 'HC165 is an 8-bit serial shift register that,
when clocked. shifts the data toward serial
output QH. Parallel-in access to each stage is
provided by eight individual direct data inputs
that are enabled by a low level at the SH/lD
input. The 'HC165 also features a clock inhibit
function and a complementary serial output QH.
Clocking is accomplished by a low-to-high
transition of the ClK input while SH/lD is held
high and ClK INH is held low. The functions of
the ClK and ClK INH (clock inhibit) inputs are
interchangeable. Since a low ClK input and a
low-to-high transition of ClK INH will also
accomplish clocking, ClK INH should be
changed to the high level only while the ClK
input is high. Parallel loading is inhibited when
SH/lD is held high. While SHllD is low, the
parallel inputs to the register are enabled
independently of the levels of ClK, ClK INH, or
SER inputs.

SN54HC166 ... FK PACKAGE

The 'HC166 parallel-in or serial-in, serial-out
registers feature gated clock inputs and an
overriding clear input. The parallel-in or serial-in
modes are 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 lowto-high-Ievel edge of the clock pulse through a
two-input positive NOR gate permitting one input
to be used as a clock-enable or clock-inhibit
function. Holding either of the clock inputs high
inhibits clocking; holding either low enables the
other clock input. This, of course, 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 when the clock
input is high. A direct clear input overrides all
other inputs, including the clock, and resets all
flip-flops to zero.

The 'HC 173 4-bit registers include D-type flipflops featuring totem-pole 3-state outputs
capable of driving highly capacitive or relatively
low-impedance loads. The high-impedence third
state and increased drive provide these flip-flops
with the capability of being connected directly
to and driving the lines in a bus-organized system
without need for interface or pull-up
components.
Gated enable inputs are provided on these
devices for controlling the entry of data into the
flip-flops. When both data-enable inputs are low,
data at the D inputs are loaded into their
respective flip-flops on the next positive
transition of the clock input. Gate output-control
inputs are also provided. When both are low, the
normal logic states (high or low levels) 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 function table.

When either M or N (or both) is (are) high. the output is
disabled to the high-impedence state; however. sequential
operation of the flip-flops is not affected.

The SN54HC173 is characterized for operation
over the full military temperature range of
-55°C to 125°C. The SN74HC173 is
characterized for operation from - 40°C to
85°C.

The SN54HC174 and SN54HC175 are
characterized for operation over the full military
temperature range of - 55°C to 125°C. The

Information at the D inputs meeting the setup
time requirements is transferred to the 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 edge of the clock
pulse. When the clock input is at either the high
or low level, the D input signal has no effect at
the output.

These universal. monolithic, 9-bit (8 data bits
plus 1 parity bit) parity generators/checkers,
feature odd/even outputs and control inputs to
facilitate operation in either odd- or even-parity
applications, Depending on whether even or odd
parity is being generated or checked, the even
or odd inputs can be utilized as the parity or 9thbit input. The word-length capability is easily
expanded by cascading.

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

3

Synchronous parallel loading is accomplished by
applying the 4 bits of data and taking both mode
control inputs, SO and S 1, high, The data are
loaded into the associated flip-flops and appear
at the outputs after the positive transition of the
clock input, During loading, serial data flow is
inhibited,

Parallel loading is accomplished by applying the
4-bits of data and taking the shift/load 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.
Shifting is accomplished synchronously when
the shift/load 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-, 0-, or T-type flip-flop as shown in the
function table.

description

II)

The SN54HC237 is characterized for operation
over the full military temperature range of
- 55°C to 125°C. The SN74HC237 is
characterized for operation from -40°C to
85°C.

Q)

SN54HC237 ... FK PACKAGE

The 'HC237 is a three-line to eight-line decoder/
demultiplexer with latches on the three address
inputs. When the latch-enable (GL) is low, the
'HC237 acts as a decoder/demultiplexer. When
GL goes from low to high, the address present
at the select inputs (A, B, and C) is stored in the
latches. Further address changes are ignored as
long as GL remains high. The output enable
controls, G1 and G2, control the outputs
independently of the select or latch-enable
inputs. All of the outputs are forced low if G 1
is low or G2 is high. The 'HC237 is ideally suited
for implementing glitch-free decoders in strobed
(stored-address) applications in bus-oriented
systems.

description

U)

The 'HCT237 is a three-line to eight-line
decoder/demultiplexer with latches on the three
address inputs. When the latch-enable input (GL)
is low, the 'HCT237 acts as a decoder/
demultiplexer. When GL goes from low to high,
the address present at the select inputs (A, B,
and C) is stored in the latches. Further address
changes are ignored as long as GL remains high.
The output enable controls, G1 and G2, control
the outputs independently of the select or latchenable inputs. All of the outputs are forced low
if G1 is low or G2 is high. The 'HCT237 is ideally
suited for implementing glitCh-free decoders in
strobed (stored-address) applications in busoriented systems.

U uo
co<{z>>-

The 'HC238 circuit is designed to be used in
high-performance memory-decoding or datarouting applications requiring very short
propagation delay times. In high-performance
memory systems, this decoder can be used to
minimize the effects of systems decoding. When
employed with high-speed memories utilizing a
fast enable circuit, the delay times of this
decoder and the enable time of the memory 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 conditions at the binary select inputs and the
three enable inputs select one of eight input
lines. 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 without external inverters and
a 32-line decoder requires only one inverter. An
enable input can be used as a data input for
demultiplexing applications.

description

U

The 'HC239 circuit is designed to be used in
high-performance memory-decoding or datarouting applications requiring very short
propagation delay times. In high-performance
memory systems this decoder can be used to
minimize the effects of system decoding. When
employed with high-speed memories utilizing a
fast enable circuit, the delay times of this
decoder and the enable time of the memory 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 'HC239 is comprised of two individual twoline to four-line decoders in a single package. The
active-low enable input can be used as a data
line in demultiplexing applications. These
decoders/demultiplexers feature fully buffered
inputs, each of which represents only one
normalized load to its driving circuit.

description

These parts differ from their TTL counterparts
(LS, ALS, and AS) in that these CMOS parts do
not have a bus-latching mode in which both the
outputs are simultaneously enabled. Instead of
this latched mode, the buses are isolated, thus
preventing potential bus conflicts if both buses
are active. However, with the exception of the
fourth line of the function table, their functional
operation is identical to their TTL counterparts.
The two enables have been renamed G1 and G2
since they work together to determine the
direction of transmission rather than each enable
controlling one direction independently of the
other. Whenever G1 and G2 are at opposite logic
levels with respect to each other, isolation
between buses results.

In

(TOP VIEWI

These four-data line tranceivers are designed for
asynchronous two-way communications
between data buses. The SN74HC' devices can
be used to drive terminated lines down to 133 n.

These data selectors/multiplexers contain full
binary decoding to select one-of-eight data
sources and feature strobe-controlled
complementary three-state outputs.
The three-state outputs can interface with and
drive 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. Both outputs are
controlled by the strobe (<3). The outputs are
disabled when G is high.

Each of these data selectors/multiplexers
contains inverters and drivers to supply full
binary decoding data selection to the AND-OR
gates. Separate output control inputs are
provided for each of the two four-line sections.
The three-state outputs can interface with and
drive 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. Each output has its
own strobe (G). The output is disabled when its
strobe is high.
The SN54HC253 is characterized for operation
over the full military temperature range of
- 55°C to 125°C. The SN74HC253 is
characterized for operation from - 40°C to
85°C.

ITOPVIEWI

These devices are designed to multiplex signals
from four-bit data sources to four-output data
lines in bus-organized systems. The 3-state
outputs will not load the data lines when the
output control pin (G) is at a high-logic level.

3

The SN54HC257 and SN54HC258 are
characterized for operation over the full military
temperature range of - 55°C to 125°C. The
SN74HC257 and SN74HC258 are characterized
for operation from - 40°C to 85 °C.

Four distinct modes of operation are selectable
by controlling the clear (ClR) and enable (G)
inputs as enumerated in the function table. In the
addressable-latch mode, data at the data-in
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, enable G 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.

description
These circuits are positive-edge-triggered D-type
flip-flops with a direct clear input.

3

Information at the 0 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.
The SN54HC273 is characterized for operation
over the full military temperature range of
- 55 DC to 125 DC. The SN74HC273 is
characterized for operation from - 40 DC to
85 D C.

These improved full adders perform the addition
of two 4-bit binary words. The sum (E) 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 generating the carry term.
This capability provides the system designer
with partial look-ahead performance at the
economy and reduced package count of a ripplecarry implementation,

The adder logic, including the carry, is
implemented in its true form. End around carry
can be accomplished without the need for logic
or level inversion.
The SN54HC283 is characterized for operation
over the full military temperature range of
- 55°C to 125°C. The SN74HC283 is
characterized for operation from -40°C to
85°C.

When the Word-Select (WS) input is low, word
one (A 1, B1, C1, 01) is applied to the flip-flops.
A high Word-Select input causes word two
(A2. B2, C2, 02) to be selected. The selected
word is clocked to the output terminals on the
negative-going edge of the clock pulse.

These eight-bit universal registers feature
multiplexed 1/0 ports to achieve full eight-bit
handling in a single 20-pin package. 'HC299

registers.

Two function-select inputs and two output
control inputs can be used to choose the modes
of operation listed in the function table.
Synchronous parallel loading is accomplished by
taking both function-select lines, SO and 51,
high, This places the three-state outputs in a
high-impedance state, which permits data that
is applied on the 110 ports to be clocked into the
register. Reading out of this 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. Taking either of the output
controls, G1 or G2, high disables the outputs but
does not affect the shifting or storage of data.

description
These monolithic data selectors/multiplexers
contain full on-chip binary decoding to select one
of eight data sources. The data-select is stored
in transparent latches that are enabled by a low
level on pin 11. SC. A similar enable for data is
obtained by a low level on pin 8. DC.
The SN54HC354 is characterized for operation
over the full military temperature range of
- 55°C to 125°C. The SN74HC354 is
characterized for operation from - 40°C to
85°C.

aQUaQ

The output control (OC) does not affect the
internal operations of the latches. Old data can
be retained or new data can be entered while the
outputs are off.
The SN54HC373 is characterized for operation
over the full military temperature range of
-55°C to 125°C. The SN74HC373 is
characterized for operation from - 40°C to
85°C.

CD

ITOP VIEWI

The eight latches of the 'HC373 are transparent
O·type latches, While the enable (C) is high. the
Q outputs will follow the data (0) inputs, When
the enable is taken low. the Q outputs will be
latched at the levels that were set up at the 0
inputs,
An output·control input (OC) 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 high·impedance third state and
increased drive provide the capability to drive the
bus lines in a bus·organized system without need
for interface or pull·up components.

':;

SN54HC373 ... FK PACKAGE

These 8·bit latches feature three·state outputs
designed specifically for driving highly capacitive
or relatively low·impedance loads, They are
particularly suitable for implementing buffer
registers, 1/0 ports. bidirectional bus drivers. and
working registers,

These 8-bit latches feature three-state outputs
designed specifically for driving highly capacitive
or relatively low-impedance loads. They are
particularly suitable for implementing buffer
registers, 110 ports, bidirectional bus drivers, and
working registers.

The eight latches of the 'HCT373 are
transparent D-type latches. While the enable (C)
is high the Q outputs will follow the data (D)
inputs. When the enable is taken low, the Q
outputs will be latched at the levels that were
set at the D inputs.

An output-control input (OC) can be used to
place the eight outputs in either a normal logic
state (high or low logic levels) or a highimpedance state. In the high-impedance state
the outputs neither load nor drive the bus lines
significantly. The high-impedance third state and
increased drive provide the capability to drive the
bus lines in a bus-organized system without need
for interface or pull-up components.

The output control (DC) does not affect the
internal operations of the latches. Old data can
be retained or new data can be entered while the

The SN54HCT373 is characterized for operation
over the full military temperature range of
- 55°C to 125°C. The SN74HCT373 is
characterized for operation from -40°C to
85°C.

These 8-bit flip-flops feature three-state outputs
designed specifically for driving highly capacitive
or relatively low-impedance loads. They are
particularly suitable for implementing buffer

An output-control input (OC) can be used to
place the eight outputs in either a normal logic
state (high or low logic levels) or a highimpedance state. In the high-impedance state,
the outputs neither load nor drive the bus lines
significantly. The high-impedance third state and
increased drive provide the capability to drive the
bus lines in a bus-organized system without need
for interface or pull-up components.
The output control (OC) does not affect the
internal operation of the flip-flops. Old data can
be retained or new data can be entered while the
outputs are in the high-impedance state.

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 (0)
input is transferred to the Q output when the
enable (C) is high and the Q 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 occurred) is retained at the Q output
until the enable goes high.
The SN54HC375 is characterized for operation
over the full military temperature range of
-55 D C to 125 D C. The SN74HC375 is
characterized for operation from - 40 DC to
85 D C.

description
Each of these monolithic circuits contains eight
flip-flops and additional gating to implement two
individual four-bit counters in a single package.
The 'HC390 incorporates dual divide-by-two and
divide-by-five counters, which can be used to
implement cycle lengths equal to any whole
and/or cumulative multiples of 2 and/or 5 up to
divide-by-100. When connected as a biquinary
counter, the separate divide-by-two circuit can
be used to provide symmetry (a square wave)
at the final output stage. The 'HC393 comprises
two independent four-bit binary counters each
having a clear and a clock input. N-bit binary
counters can be implemented with each package
providing the capability of divide-by-256. The
'HC390 and 'HC393 have parallel outputs from
each counter stage so that any submultiple of
the input count frequency is available for systemtiming signals.
The SN54HC390 and SN54HC393 are
characterized for operation over the full military
temperature range of - 55°C to 125°C. The
SN74HC390 and SN74HC393 are characterized
for operation from - 40°C to 85 °C.

Each of these monolithic circuits contains eight
master-slave flip-flops and additional gating to
implement two individual 4-bit decade counters
in a single package, Each decade counter has
individual clock, clear. and set-to-9 inputs. BCD
count sequences of any length up to divideby- 100 may be implemented with a single
'HC490. The counters have parallel outputs from
each counter stage so that submUltiples of the
input count frequency are available for system
timing signals,
The SN54HC490 is characterized for operation
over the full military temperature range of
- 55°C to 125°C. The SN74HC490 is
characterized for operation from - 40°C to
85°C.

SN54HC533 ... FK PACKAGE

These 8-bit latches feature three-state outputs
designed specifically for driving highly capacitive
or relatively low-impedance loads, They are
particularly suitable for implementing buffer
registers, 1/0 ports, bidirectional bus drivers, and
working registers.

CD

ITOPVIEW,

The eight latches of the 'HC 533 are transparent
D-type latches. While the enable (C) is high, the
Q outputs will follow the complements of the D
inputs. When the enable is taken low, the Q
outputs will be latched at the inverses of the
levels that were set up at the 0 inputs. The
'HC533 is functionally equivalent to the 'HC373
except for having inverted outputs.
An output-control (OC) input can be used to
place the eight outputs in either a normal logic
state (high or low logic levels) or a highimpedance state, In the high-impedance state
the outputs neither load nor drive the bus lines
significantly. The high-impedance third state and
increased drive provide the capability to drive the
bus lines in a bus-organized system without need
for interface or pull-up components.

The output control does not affect the internal
operation of the latches. Old data can be retained
or new data can be entered while the outputs
are off.

over the full military temperature range of
- 55°C to 125°C. The SN74HC533 is
characterized for operation from - 40°C to

The eight latches of the 'HCT533 are
transparent Ootype latches. While the enable (C)
is high, the IT outputs will follow the
complements of the 0 inputs. When the enable
is taken low, the IT outputs will be latched at
the inverses of the levels that were set up at the
o inputs. The 'HCT533 is functionally equivalent
to the 'HCT373 except for having inverted
outputs.

The eight flip-flops of the 'HC534 are edgetriggered D-type flip-flops. On the positive
transition of the clock, the Q outputs will be set
to the complement of the logic states that were
set up at the 0 inputs. The 'HC534 is
functionally equivalent to the 'HC374 except for
having inverted outputs.

An output-control (OC) input can be used to
place the eight outputs in either a normal logic
state (high or low logic levels) or a highimpedance state. In the high-impedance state
the outputs neither load nor drive the bus lines
significantly. The high-impedance third state and
increased drive provide the capability to drive the
bus lines in a bus-organized system without need
for interface or pull-up components.

The output control does not affect the internal
operation of the flip-flops. Old data can be

description
These 8-bit flip-flops feature three-state outputs
designed specifically for driving highly capacitive
or relatively low-impedance loads. They are
particularly attractive for implementing buffer
registers, I/O ports, bidirectional bus drivers, and
working registers.
The eight flip-flops of the 'HCT534 are edgetriggered D-type flip-flops. On the positive
transition of the clock, the Q outputs will be set
to the complement of the logic states that were
set up at the D inputs. The 'HCT534 is
functionally equivalent to the 'HCT374 except
for having inverted outputs.
An output-control (DC) input can be used to
place the eight outputs in either a normal logic
state (high or low logic levels) or a highimpedance state. In the high-impedance state
the outputs neither load nor drive the bus lines
significantly.

These octal buffers and line drivers are designed
to have the performance of the popular
SN54HCT240/SN74HCT240 series and, at the
same time, offer a pinout with inputs and
outputs on opposite sides of the package. This
arrangement greatly enhances printed circuit
board layout.
The three-state control gate is a 2-input NOR.
If either G 1 or G2 is high, all eight outputs are
in the high-impedance state.

description
These 8-bit latches feature three-state outputs
designed specifically for driving highly capacitive
or relatively low-impedance loads. They are
particularly suitable for implementing buffer
registers, I/O ports, bidirectional bus drivers, and
working registers.

The eight latches are transparent D-type latches.
While the enable (C) is high the Q outputs will
follow the complements of data (0) inputs.
When the enable is taken low the outputs will
be latched at the inverses of the levels that were
set up at the 0 inputs.

An output-control (DC) input can be used to
place the eight outputs in either a normal logic
state (high or low levels) or a high-impedance
state. In the high-impedance state the outputs
neither load nor drive the bus lines significantly.
The high-impedance state and increased highlogic level provide the capability to drive the bus
lines in a bus-organized system without need for
interface or pull-up components.

These 8-bit latches feature three-state outputs
designed specifically for driving highly capacitive
or relatively low-impedance loads. They are
particularly suitable for implementing buffer
registers, I/O ports, bidirectional bus drivers, and
working registers.
The eight latches are transparent Ootype latches.
While the enable (C) is high the
outputs will
follow the complement of data (0) inputs. When
the enable is taken low the outputs will be
latched at the inverses pf the levels that were
set up at the 0 inputs.

An output-control (OC) input can be used to
place the eight outputs in either a normal logic
state (high or low levels) or a high-impedance
state. In the high-impedance state the outputs
neither load nor drive the bus lines significantly.
The high-impedance state and increased highlogic level provide the capability to drive the bus
lines in a bus-organized system without need for
interface or pull-up components.

An output-control (OC) input can be used to
place the eight outputs in either a normal logic
state (high or low levels) or a high-impedance
state. In the high-impedance state the outputs
neither load nor drive the bus lines significantly.

The eight-bit edge-triggered Ootype flip-flops
enter data on the low-to-high transition of the
clock.

The output control does not affect the internal
operation of the flip-flops. Old data can be
retained or new data can be entered while the
outputs are in the high-impedance state.

The eight latches are transparent D-type latches.
While the enable (C) is high the (0) outputs will
respond to the data (D) inputs. When the enable
is taken low the outputs will be latched to retain
the data that was set up.
An output-control (OC) input can be used to
place the eight outputs in either a normal logic
state (high or low logic levels) or a highimpedance state. In the high-impedance state
the outputs neither load nor drive the bus lines
significantly. The high-impedance state and
increased drive provide the capability to drive the
bus lines in a bus-organized system without need
for interface or pull-up components.

These 8-bit latches feature three-state outputs
designed specifically for driving highly capacitive
or relatively low-impedance loads. They are
particularly suitable for implementing buffer
registers. I/O ports. bidirectional bus drivers. and
working registers.

An output-control (OC) input can be used to
place the eight outputs in either a normal logic
state (high or low levels) or a high-impedance
state. In the high-impedance state the outputs
neither load nor drive the bus lines significantly.
The high-impedance state and increased drive
provide the capability to drive the bus lines in a

The SN54HC574 is characterized for operation
over the full military temperature range of
- 55°C to 125°C. The SN74HC574 is
characterized for operation from - 40°C to
85°C.

SN54HC574 ... FK PACKAGE
(TOP VIEW)

The eight edge-triggered O-type flip-flops enter
data on the low-to-high transition of the clock.
An output-control (OC) input can be used to
place the eight outputs in either a normal logic
state (high or low logic levels) or a highimpedance state. In the high-impedance state,
the outputs neither load nor drive the bus lines
significantly. The high-impedance state and
increased high-logic level provide the capability
to drive the bus lines in a bus-organized system
without need for interface or pull-up
components.

description

u

These devices each contain an 8-bit binary
counter that feeds an 8-bit storage register. The
storage register has parallel outputs. Separate
clocks are provided for both the binary counter
and storage register. The binary counter features
a direct clear input CCLR and a count enable
input CCKEN. For cascading a ripple carry output
RCO is provided. Expansion is easily
accomplished for two stages by connecting RCO
of the first stage to CCKEN of the second stage.
Cascading for larger count chains can be
accomplished by connecting RCO of each stage
to CCK of the following stage.
Both the counter and register clocks are positiveedge triggered. If the user wishes to connect
both clocks together, the counter state will
always be one count ahead of the register.
Internal circuitry prevents clocking from the
clock enable.

description
These devices each contain an a-bit serial-in.
parallel-out shift register that feeds an a-bit Dtype storage register. The storage register has
parallel 3-state outputs. Separate clocks are
provided for both the shift register and storage
register. The shift register has a direct-overriding
clear. serial input. and serial output pins for
cascading.

Both the shift register and storage register clocks
are positive-edge triggered. If the user wishes to
connect both clocks together. the shift register
state will always be one clock pulse ahead of the
storage register.
The SN54HC595 is characterized for operation
over the full military temperature range of
-55°C to 125°C. The SN74HC595 is
characterized for operation from - 40°C to a5°C.

description

These octal bus transceivers are designed for
asynchronous two-way communication
between data buses. The control function
implementation allows for maximum flexibility in
timing.
These devices allow data transmission from the
A bus to the B bus or from the B bus to the A
bus depending up'on the logic levels at the enable
inputs (GBA and GAB.)

(!)

The enable inputs can be used to disable the
device so that the buses are effectively isolated.
The dual-enable configuration gives these
devices the capability to store data by
simultaneous enabling of GBA and GAB; Each
output reinforces its input in this transceiver
configuration. Thus when both control inputs are
enabled and all other data sources to the two
sets of bus lines are at high impedance, both sets
of bus lines (16 in all) will remain at their last
states. The 8-bit codes appearing on the two
sets of buses will be identical for the 'HC623 or
complementary for the 'HC620.
The SN54HC620 and SN54HC623 are
characterized for operation over the full military
temperature range of - 55°C to 125°C. The
SN74HC620 and SN74HC623 are characterized
for operation from -40°C to 85°C.

These octal bus transceivers are designed for
asynchronous two-way communication
between data buses. The devices transmit data
from the A bus to the B bus or from the B bus
to the A bus depending upon the level at the
direction control (DIR) input. The enable input (G)
can be used to disable the device so the buses
are effectively isolated.

description

These octal bus transceivers are designed for
asynchronous two-way communication
between data buses. The devices transmit data
from the A bus to the B bus or from the B bus
to the A bus depending upon the level at the
direction control (DIR) input. The enable input (<3)
can be used to disable the device so the buses
are effectively isolated.

These devices consist of bus transceiver circuits
with 3-state outputs, D-type flip-flops, and
control circuitry arranged for multiplexed
transmission of data directly from the input bus
or from the internal registers. Data on the A or
B bus will be clocked into the registers on the
low-to-high transition of the appropriate clock
pin (CAB or CSA). The examples on the following
page demonstrate the four fundamental busmanagement functions that can be performed
with the 'HC646 or 'HC648.

Enable (G) and direction (DIR) pins are provided
to control the transceiver functions. In the
transceiver mode, data present at the highimpedance port may be stored in either register
or in both. The select controls (SAB and SBA)
can multiplex stored and real-time (transparent
model data. The direction control determines
which bus will receive data when the enable G is
active (low). In the isolation mode (enable G
high), A data may be stored in one register and/or
B data may be stored in the other register.

When an output function is disabled, the input
function is still enabled and may be used to store
and transmit data. Only one of the two buses,
A or B, may be driven at a time.
The SN54HC' family is characterized for
operation over the full military temperature range
of - 55°C to 125°C. The SN74HC' family is
characterized for operation from - 40°C to
85°C.

SN54HCT' ... FK PACKAGE

These devices consist of bus transceiver circuits
with 3-state outputs, D-type flip-flops, and
control circuitry arranged for multiplexed
transmission of data directly from the input bus
or from the internal registers. Data on the A or
B bus will be clocked into the registers on the
low-to-high transition of the appropriate clock
pin (CAB or CBA). The examples on the following
page demonstrate the four fundamental busmanagement functions that can be performed
with the 'HCT646 or 'HCT648.
Enable {G) and direction (DIR) pins are provided
to control the transceiver functions. In the
transceiver mode, data present at the highimpedance port may be stored in either register
or in both. The select controls (SAB and S8A)
can multiplex stored and real-time (transparent
mode) data. The direction control determines
which bus will receive data when the enable G is
active (low). In the isolation mode (enable G
high), A data may be stored in one register andlor
B data may be stored in the other register.

When an output function is disabled, the input
function is still enabled and may be used to store
and transmit data. Only one of the two buses,
A or 8, may be driven at a time.
The SN54HCT' family is characterized for
operation over the full military temperature range
of - 55°C to 125°C. The SN74HCT' family is
characterized for operation from - 40°C to
85°C.

description
These devices consist of bus transceiver circuits,
D-type flip-flops. and control circuitry arranged
for multiplexed transmission of data directly from
the data bus or from the internal storage
registers. Enable GAB and GBA are provided to
control the transceiver functions. SAB and SBA
control pins are provided to select whether realtime or stored data is transferred. A low input
level selects real-time data, and a high selects
stored data. The examples on the following page
demonstrate the four fundamental busmanagement functions that can be performed
with the 'HC651 and 'HC652.

«<2«<

Data on the A or B data bus, or both, can be
NC-No internal connection
stored in the internal D flip-flops by low-to-high
transitions at the appropriate clock pins (CAB or
CBA) regardless of the select or enable control pins. When SAB and SBA are in the real-time transfer mode,
it is also possible to store data without using the internal D-type flip-flops by simultaneously enabling GAB
and GBA. In this configuration each output reinforces its input. Thus, when all other data sources to the
two sets of bus lines are at high impedance, each set of bus lines will remain at its last state.
The SN54HC651 and SN54HC652 are characterized for operation over the full military temperature range
of -55°C to 125°C. The SN74HC651 and SN74HC652 are characterized for operation from -40°C
to 85°C.

description

o

~~~utl~~

These devices consist of bus transceiver circuits,
D-type flip-flops, and control circuitry arranged
for multiplexed transmission of data directly from
the data bus or from the internal storage
registers. Enable GAB and GBA are provided to
control the transceiver functions. SAB and SBA
control pins are provided to select whether realtime or stored data is transferred. A low input
level selects real-time data, and a high selects
stored data. The examples on the following page
demonstrate the four fundamental busmanagement functions that can be performed
with the 'HCT651 and 'HCT652.

description
The 'HC679 address comparator simplifies
addressing of memory boards and/or other
peripheral devices. The four P inputs are normally
hard wired with a preprogrammed address. An
internal decoder determines what input
information applied tothe 12-A inputs must be
low or high to cause a low state at the output
(Y). For example, a positive-logic bit combination
of 0111 (decimal 7) at the P input determines
that inputs A 1 through A 7 must be low and that
inputs AS through A 12 must be high to cause
the output to go low. Equality of the address
applied at the A inputs to the preprogrammed
address is indicated by the output being low.

The 'HC679 features an enable input (G). When

«z~~~

el«««

G is low, the device is enabled. When G is high,
the device is disabled and the output is high
regardless of the A and P inputs.

The 'HC679 is functionally unilaterally interchangeable with its TTL ALS counterpart, 'ALS679 in all cases
of normal use as 12-bit address comparators. They differ in two respects. First, they may be programmed
to recognize all A inputs low either by connecting all P inputs high (1111 = decimal 15), or by combination
HHLL (1100 = 12), the latter option not being valid for the TTL ALS parts. Second, the combinations
HHLH and HHHL (1101 = 13 and 1110 = 14) cannot be used (but are not needed) in address-comparator
applications. These two combinations cause the outputs to be disabled (high).
The SN54HC679 is characterized for operation over the full military temperature range of - 55°C to 125°C.
The SN74HC679 is characterized for operation from -40°C to 85°C.

In order to understand the
implementation of this device. it
is essential that the function of
the
vertical
string
of
transmission
gates
be
understood. A schematic of one
of these gates is shown below.
If the input to the transmission
gate labeled "X1" is high. then
the transmission path between
the two ports labeled "1" is on.
If the "X1" input is low. then
the transmission path between
the two ports labeled" 1" is off.
Only one of the 16 transmission
gates can be off while the
device is operating; which one is
off is determined by inputs PO
through P3. The lines going from
the string of transmission gates
to the Exclusive-OR gates
located above the transmission
gate that is off will be high. The
lines going to the Exclusive-OR
gates located below that
transmission gate will be low.

TYPICAL APPLICATION INFORMATION
The 'HC67S can be wired to recognize anyone of 212 addresses. The number of "lows" in the address
determines the input pattern for the P inputs. Then those system address lines that are low in the address to
be recognized are connected to the lowest numbered A inputs of the address comparator and the system address
lines that are high are connected to the highest numbered A inputs.
For example, assume the comparator is to enable a device when the 12-bit system address is:

The TlC4016 is a silicon-gate CMOS quadruple
analog switch integrated circuit designed to
handle both analog and digital signals. Each
switch permits signals with amplitudes up to
12 volts peak to be transmitted in either
direction.

Each switch section has its own enable input
control. A high-level voltage applied to this
control terminal turns on the associated switch
section.
Applications include signal gating, chopping,
modulation or demodulation (modem), and signal
multiplexing for analog-to-digital and digital-toanalog conversion systems.

The 'HC40 17 is a 5-stage divide-by-1 0 Johnson
counter with ten decoded outputs and a carryout bit, High-speed operation and spike-free
outputs are obtained by use of the Johnson
decade counter configuration,
The ten decoded outputs are normally low and
go high only at their respective decimal time
periods. A high signal on CLR asynchronously
clears the decade counter and sets the carry
output and VO high. With CLKEN low, the count
is advanced on a low-to-high transition at CLK.
Alternatively, if CLK is high, the count is
advanced on a high-to-Iow transition at CLKEN.
Each decoded output remains high for one full
clock cycle. The carry output CO is high while
YO, V1, V2, V3, or V4 is high, then is low while
V5, V6, V7, VB, or V9 is high.

The 'HC4024 is an asynchronous 7-stage binary
counter designed with an input pulse-shaping
circuit. The outputs of all stages are available
externally. A high clear signal asynchronously
clears the counter and resets all outputs low. The
count is advanced on the high-to-Iow transition
of the clock pulse. Applications include timedelay circuits, counter controls, and frequencydividing circuits.

This device is an asynchronous 12-stage binary
counter with the outputs of all stages available
externally, A high level at ClR asynchronously
clears the counter and resets all outputs low. The
count is advanced on a high-to-Iow transition at
ClK. Applications include time delay circuits,
counter controls, and frequency-dividing circuits,

description
The 'HC4060 consists of an oscillator section
and 14 ripple-carry binary counter stages. The
oscillator configuration allows design of either
RC or crystal oscillator circuits. A high-to-Iow
transition on the clock input increments the
counter. A high level at CLR disables the
oscillator (CKO goes high and CKO goes low) and
resets the counter to zero (all Q outputs low).

CONNECTING AN RC OSCILLATOR CIRCUIT TO THE 'HC4060
The 'HC4060 consists of an oscillator section and 14 ripple-carry binary counter stages. The oscillator
configuration allows design of either RC or crystal oscillator circuits.
When a RC oscillator circuit is implemented, two resistors and a capacitor are required. The components are
attached to the chip as follows:

To determine the values of capacitance and resistance necessary to obtain a specific oscillator frequency f,
the following formula is used:

If R2> > R1 (i.e. R2 = 1OR1), then the above formula simplifies to:

description
The 'HC4061 consists of an oscillator section
and 14 ripple-carry binary counter stages. The
oscillator configuration allows design of either
RC or crystal oscillator circuits. A high-to-Iow
transition on the clock input increments the
counter. A high level at CLR resets the counter
to zero (all Q outputs low) but has no effect on
the oscillator.

The TLC4066 is a silicon-gate CMOS quadruple
analog switch integrated circuit designed to
handle both analog and digital signals. Each
switch permits signals with amplitudes up to
12 volts peak to be transmitted in either
direction.
Each switch section has its own enable input
control. A high-level voltage applied to this
control terminal turns on the associated switch
section.

These devices present two output options of a
4-line to 16-line decoder with latched inputs. The
'HC4514 presents a high level at the selected
output.
These devices consist of four storage latches
with common latch enable (LE) and inhibit (0)
inputs. When a low signal is applied to the LE
input, the input data is stored, decoded, and

Four distinct modes of operation are selectable
by controlling the clear (ClR) and enable (G)
inputs as enumerated in the function table. In the
addressable-latch mode, data at the data-in
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, enable G 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.

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 singleline data in eight addressable latches, and being
a 1-of-8 decoder or demultiplexer with activehigh outputs.

The SN54HC7074 and SN74HC7074 are each
comprised of the following sections:
Two inverters
One 2-input NOR gate
One 2-input NAND gate
Two D-type flip-flops
They perform the Boolean functions shown
under the respective function table.

The D-type flip-flops are positive-edge-triggered
and are functionally similar to the SN54HC74
and SN74HC74. A low level at the PRE or CLR
inputs sets or resets the outputs regardless of
the levels of the other inputs. When PRE and CLR
are inactive (high). data at the D input meeting
the setup time requirements are transferred to
the outputs on the positive-going edge of the
clock pulse. Clock triggering occurs at a voltage
level and is not directly related to the rise time
of the clock pulse. Following the hold time
interval. data at the D input may be changed
without affecting the levels at the outputs.
The SN54HC7074 is characterized for operation
over the full military temperature range of
-55°C to 125°C. The SN74HC7074 is
characterized for operation from -40°C to
85°C.

Explanation of Logic Symbols t

3.1

Introduction
The International Electrotechnical Commission (lEC) has been developing a
very powerful symbolic language that can show the relationship of each input
of a digital logic circuit to each output without showing explicitly the internal
logic. At the heart of the system is dependency notation, which will be
explained in section 3.4.
The system was introduced in the USA in a rudimentary form in IEEE/ANSI
Standard Y32.14-1973. Lacking at that time a complete development of
dependency notation, it offered little more than a substitution of rectangular
shapes for the familiar distinctive shapes for representing the basic functions
of AND, OR, negation, etc. This is no longer the case.
Internationally, IEC Technical Committee TC-3 has approved a new document
(Publication 617-12) that consolidates the original work started in the mid
1960s and published in 1972 (Publication 117-15) and the amendments and
supplements that have followed. Similarly for the USA, IEEE Committee SCC
11.9 has revised the publication IEEE Std 91/ANSI Y32.14. Now numbered
simply IEEE Std 91-1984, the IEEE standard contains all of the IEC work that
has been approved, and also a small amount of material still under international
consideration. Texas Instruments is participating in the work of both
organizations, and this document introduces new logic symbols in accordance
with the new standards. When changes are made as the standards develop,
future editions will take those changes into account.
The following explanation of the new symbolic language is necessarily brief
and greatly condensed from what the standards publications now contain.
This is not intended to be sufficient for those people who will be developing
symbols for new devices. It is primarily intended to make possible the
understanding of the symbols used in various data books and the comparison
of the symbols with logic diagrams, functional block diagrams, and/or function
tables to further help that understanding.

Symbol Composition
A symbol comprises an outline or a combination of outlines together with
one or more qualifying symbols. The shape of the symbol is not Significant.
As shown in Figure 3-1 , general qualifying symbols are used to tell exactly
what logical operation is performed by the elements. Table 3-1 shows general
qualifying symbols defined in the new standards. Input lines are placed on
the left and output lines are placed on the right. When an exception is made
to that convention, the direction of signal flow is indicated by an arrow as
shown in Figure 3-11 .

GENERAL QUALIFYING
SYMBOL

*Possible positions for qualifying symbols relating to inputs and outputs

Figure 3-1. Symbol Composition
All outputs of a single, unsubdivided element always have identical internal
logic states determined by the function of the element except when otherwise
indicated by an associated qualifying symbol or ·'abe' inside the element.
The outlines of elements may be abutted or embedded in which case the
following conventions apply. There is no logic connection between the
elements when the line common to their outlines is in the direction of signal
flow. There is at least one logic connection between the elements when the
line common to their outlines is perpendicular to the direction of signal flow .
The number of logic connections between elements will be clarified by the
use of qualifying symbols, and this is discussed further under that topic. If
no indications are shown on either side of the common line, it is assumed
there is only one connection.
When a circuit has one or more inputs that are common to more than one
element of the circuit, the common-control block may be used. This is the
only distinctively shaped outline used in the lEe system. Figure 3-2 shows
that, unless otherwise qualified by dependency notation, an input to the
common-control block is an input to each of the elements below the commoncontrol block.
A common output depending on all elements of the array can be shown as
the output of a common-output element. Its distinctive visual feature is the
double line at its top. In addition, the common-output element may have other
inputs as shown in Figure 3-3. The function of the common-output element
must be shown by use of a general qualifying symbol.

3.3.2

General Qualifying Symbols for Inputs and Outputs
Qualifying symbols for inputs and outputs are shown in Table 3-2, and many
will be familiar to most users, a likely exception being the logic polarity symbol
for directly indicating active-low inputs and outputs. The older logic negation
indicator means that the external 0 state produces the internal 1 state. The
internal 1 state means the active state. Logic negation may be used in pure
logic diagrams; in order to tie the external 1 and 0 logic states to the levels
H (high) and L (low), a statement of whether positive logic (1 = H, 0 = L)
or negative logic (1 = L,O = H) is being used is required or must be assumed.
Logic polarity indicators eliminate the need for calling out the logic convention
and are used in various data books in the symbology for actual devices. The
presence of the triangular polarity indicator indicates that the L logic level
will produce the internal 1 state (the active state) or that, in the case of an
output, the internal 1 state will produce the external L level. Note how the
active direction of transition for a dynamic input is indicated in positive logic,
negative logic, and with polarity indication.
The internal connections between logic elements abutted together in a symbol
may be indicated by the symbols shown in Table 3-2. Each logic connection
may be shown by the presence of qualifying symbols at one or both sides
of the common line, and, if confusion can arise about the number of
connections, use can be made of one of the internal connection symbols.

The internal (virtual) input is an input originating somewhere else in the circuit
and is not connected directly to a terminal. The internal (virtual) output is
likewise not connected directly to a terminal. The application of internal inputs
and outputs requires an understanding of dependency notation, which is
explained in section 3.4.

In an array of elements, if the same general qualifying symbol and the same
qualifying symbols associated with inputs and outputs would appear inside
each of the elements of the array, then these qualifying symbols are usually
shown only in the first element. This is done to reduce clutter and to save
time in recognition. Similarly, large identical elements that are subdivided into
smaller elements may each be represented by an unsubdivided outline. The
SN54HC242 or SN54LS440 symbol illustrates this principle.

3.3.3

Symbols Inside the Outline
Table 3-3 shows some symbols used inside the outline. Note particularly that
open-collector (open-drain), open-emitter (open-source), and 3-state outputs
have distinctive symbols. An EN input affects all the external outputs of the
element in which it is placed, plus the external outputs of any elements shown
to be influenced by that element. It has no effect on inputs. When an enable
input affects only certain outputs, affects outputs located outside the indicated
influence of the element in which the enable input is placed, and/or affects
one or more inputs, a form of dependency notation will indicate this (see
3.4.10). The effects of the EN input on the various types of outputs are shown.

It is particularly important to note that a D input is always the data input of
a storage element. At its internal 1 state, the D input sets the storage element
to its 1 state, and at its internal 0 state, it resets the storage element to its
o state.

The binary grouping symbol will be explained more fully in section 3.8. Binaryweighted inputs are arranged in order, and the binary weights of the least
significant and the most significant lines are indicated by numbers. In this
document, weights of input and output lines will usually be represented by
powers of two only when the binary grouping symbol is used; otherwise,
decimal numbers will be used. The grouped inputs generate an internal number
on which a mathematical function can be performed or that can be an
identifying number for dependency notation (Figure 3-31). A frequent use is
in addresses for memories.

Reversed in direction, the binary grouping symbol can be used with outputs.
The concept is analogous to that for the inputs, and the weighted outputs
will indicate the internal number assumed to be developed within the circuit.
Other symbols are used inside the outlines in accordance with the IEC/lEEE
standards but are not shown here. Generally, these are associated with
arithmetic operations and are self-explanatory.
When nonstandardized information is shown inside an outline, it is usually
enclosed in square brackets [like thesel. The square brackets are omitted when
associated with a nonlogic input, which is indicated by an X superimposed

Dependency Notation

3.4.1

General Explanation
Dependency notation is the powerful tool that sets the IEC symbols apart from
previous systems and makes compact, meaningful symbols possible. It provides
the means of denoting the relationship between inputs, outputs, or inputs and
outputs without actually showing all the elements and interconnections involved.
The information provided by dependency notation supplements that provided
by the qualifying symbols for an element's function.
In the convention for the dependency notation, use will be made of the terms
"affecting" and "affected." In cases where it is not evident which inputs must
be considered as being the affecting or the affected ones (e.g., if they stand
in an AND relationship), the choice may be made in any convenient way.
So far, eleven types of dependency have been defined, and all of these are used
in various TI data books. X dependency is used mainly with CMOS circuits. They
are listed below in the order in which they are presented and are summarized
in Table 3-4 following 3.4.12.

G (AND) Dependency
A common relationship between two signals is to have them ANDed together.
This has traditionally been shown by explicitly drawing an AND gate with
the signals connected to the inputs of the gate. The 1972 lEe publication
and the 1973 IEEE/ANSI standard showed several ways to show this AND
relationship using dependency notation. While ten other forms of dependency
have since been defined, the ways to invoke AND dependency are now
reduced to one.
In Figure 3-4 input b is ANDed with input a, and the complement of b is ANDed
with c. The letter G has been chosen to indicate AND relationships and is
placed at input b, inside the symbol. A number considered appropriate by the
symbol designer (1 has been used here) is placed after the letter G and also
at each affected input. Note the bar over the 1 at input c.

a dynamic input b.

a-fG1-b---t 1
Figure 3-6. G Dependency with a Dynamic Input
The rules for G dependency can be summarized thus:
When a Gm input or output (m is a number) stands at its internal 1 state,
all inputs and outputs affected by Gm stand at their normally defined
internal logic states. When the Gm input or output stands at its 0 state,
all inputs and outputs affected by Gm stand at their internal 0 states.

3.4.3

Conventions for the Application of Dependency Notation in General
The rules for applying dependency relationships in general follow the same
pattern as was illustrated for G dependency.
Application of dependency notation is accomplished by:
1)

2)

labeling the input (or output) affecting other inputs or outputs
with the letter symbol indicating the relationship involved (e.g.,
G for AND) followed by an identifying number, appropriately
chosen, and
labeling each input or output affected by that affecting input
(or output) with that same number.

If it is the complement of the internal logic state of the affecting input or output
that does the affecting, then a bar is placed over the identifying numbers at
the affected inputs or outputs (Figure 3-4).
If two affecting inputs or outputs have the same letter and the same identifying
number, they stand in an OR relationship to each other (Figure 3-7).

Figure 3-7. ORed Affecting Inputs
If the affected input or output requires a label to denote its function (e.g.,
"D"), this label will be prefixed by the identifying number of the affecting
input (Figure 3-15).
If an input or output is affected by more than one affecting input, the
identifying numbers of each of the affecting inputs will appear in the label

3-13

of the affected one, separated by commas. The normal reading order of these
numbers is the same as the sequence of the affecting relationships
(Figure 3-15).
If the labels denoting the functions of affected inputs or outputs must be
numbers (e.g., outputs of a coder), the identifying numbers to be associated
with both affecting inputs and affected inputs or outputs may be replaced
by another character selected to avoid ambiguity, e.g., Greek letters
(Figure 3-8).

Although the transmission paths represented by X dependency are inherently
bidirectional, use is not always made of this property. This is analogous to

C (Control) Dependency
The symbol denoting control dependency is the letter C.
Control inputs are usually used to enable or disable the data (0, J, K, R, or
S) inputs of storage elements. They may take on their internal 1 states.(be
active) either statically or dynamically. In the latter case, the dynamic input
symbol is used as shown in the third example of Figure 3-15.
When a Cm input or output stands at its internal 1 state, the inputs affected
by Cm have their normally defined effect on the function of the element; i.e.,
these inputs are enabled. When a Cm input or output stands at its internal
o state, the inputs affected by Cm are disabled and have no effect on the
function of the element.

5 (Set) and R (Reset) Dependencies
The symbol denoting set dependency
is the letter S. The symbol denoting
reset dependency is the letter R.
Set and reset dependencies are used
if it is necessary to specify the effect
of the combination R = S = 1 on a
bistable element. Case 1 in
Figure 3-16 does not use S or R
dependency.
When an Sm input is at its internal 1
state, outputs affected by the Sm
input will react, regardless of the
state of an R input, as they normally
would react to the combination S = 1 ,
R = O. See cases 2, 4, and 5 in
Figure 3-16.
When an Rm input is at its internal 1
state, outputs affected by the Rm
input will react, regardless of the
state of an S input, as they normally
would react to the combination S = 0,
R = 1. See cases 3, 4, and 5 in
Figure 3-16.
When an Sm or Rm input is at its
internal 0 state, it has no effect.
Note that the noncomplementary
output patterns in cases 4 and 5 are
only pseudo stable. The simultaneous
return of the inputs to S =R =0
produces an unforeseeable stable and
complementary output pattern.

3.4.10 EN (Enable) Dependency
The symbol denoting enable dependency is the combination of letters EN.
An ENm input has the same effect on outputs as an EN input, see 3.3.3, but
it affects only those outputs labeled with the identifying number m. It also
affects those inputs labeled with the identifying number m. By contrast, an
EN input affects all outputs and no inputs. The effect of an ENm input on
an affected input is identical to that of a Cm input (Figure 3-17).

M dependency affects inputs the same as C dependency. When an Mm input

element; i.e., the inputs are enabled.
When an Mm input or Mm output stands at its internal 0 state, the inputs
affected by this Mm input or Mm output have no effect on the function of
the element. When an affected input has several sets of labels separated by
solidi (e.g., C4/2-+/3 + l. any set in which the identifying number of the Mm
input or Mm output appears has no effect and is to be ignored. This represents
disabling of some of the functions of a multifunction input.

3-20

The circuit in Figure 3-18 has two inputs, band c, that control which one
of four modes (0, 1, 2, or 3) will exist at any time. Inputs d, e, and fare D
inputs subject to dynamic control (clocking) by the a input. The numbers 1
and 2 are in the series chosen to indicate the modes so inputs e and fare
only enabled in mode 1 (for parallel loading). and input d is only enabled in
mode 2 (for serial loading). Note that input 8 has three functions. It is the
clock for entering data. In mode 2, it causes right shifting of data, which means
a shift away from the control block. In mode 3, it causes the contents of the
register to be incremented by one count.
Note that all o'perations are synchronous.
In MODE 0 (b =0, c =0), the outputs
remain at their existing states as none
of the inputs has an effect.

Figure 3-22. Dependent Relationships
Affected by Mode
At output e, the label set causing negation (if c = 1) is effective only in modes
2 and 3. In modes 0 and 1, this output stands at its normally defined state
as if it had no labels. At output f, the label set has effect when the mode
is not 0 so output e is negated (if c = 1) in modes 1, 2, and 3. In mode 0,
the label set has no effect so the output stands at its normally defined state.
In this example, 0,4 is equivalent to (1/2/3)4. At output g, there are two label
sets: the first set, causing negation (if c = 1), is effective only in mode 2;
the second set, subjecting g to AND dependency on d, has effect only in mode

3.
Note that in mode 0 none of the dependency relationships has any effect on
the outputs, so e, 1. and g will all stand at the same state.

3.4.12

A (Address) Dependency
The symbol denoting address dependency is the letter A.
Address dependency provides a clear representation of those elements,
particularly memories, that use address control inputs to select specified
sections of a multildimensional array. Such a section of a memory array is
usually called a word. The purpose of address dependency is to allow a
symbolic presentation of the entire array. An input of the array shown at a
particular element of this general section is common to the corresponding
elements of all selected sections of the array. An output of the array shown
at a particular element of this general section is the result of the OR function
of the outputs of the corresponding elements of selected sections.

Inputs that are not affected by any affecting address input have their normally
defined effect on all sections of the array, whereas inputs affected by an
address input have their normally defined effect only on the section selected
by that address input.
An affecting address input is labeled with the letter A followed by an
identifying number that corresponds with the address of the particular section
of the array selected by this input. Within the general section presented by
the symbol, inputs and outputs affected by an Am input are labeled with the
letter A, which stands for the identifying numbers, i.e., the addresses, of the
particular sections.

3-23

Figure 3-23 shows a 3-word by 2-bit memory having a separate address line
for each word and uses EN dependency to explain the operation. To select
word 1, input a is taken to its 1 state, which establishes mode 1. Data can
now be clocked into the inputs marked "1,40." Unless words 2 and 3 are
also selected, data cannot be clocked in at the inputs marked "2,40" and
"3,40." The outputs will be the OR functions of the selected outputs; i.e.,
only those enabled by the active EN functions.

The identifying numbers of affecting address inputs correspond with the
addresses of the sections selected by these inputs. They need not necessarily
differ from those of other affecting dependency inputs (e.g., G, V, N, ... l.

Figure 3-25. Four Types of Bistable Circuits

Transparent latches have a level-operated control input. The D input is active
as long as the C input is at its internal 1 state. The outputs respond
immediately. Edge-triggered elements accept data from D, J, K, R, or 5 inputs
on the active transition of C. Pulse-triggered elements require the setup of
data before the start of the control pulse; the C input is considered static since
the data must be maintained as long as C is at its 1 state. The output is
postponed until C returns to its 0 state. The data-lockout element is similar
to the pulse-triggered version except that the C input is considered dynamic
in that, shortly after C goes through its active transition, the data inputs are
disabled, and data does not have to be held. However, the output is still
postponed until the C input returns to its initial external level.
Notice that synchronous inputs can be readily recognized by their dependency
labels (1 D, 1J, 1K, 15, 1 R) compared to the asynchronous inputs (5, R), which
are not dependent on the C inputs.

produced by decoding the signals on
certain inputs to an element. In such
a case, use can be made of the

2k internal inputs. The bracket is followed by the letter denoting the type of
dependency followed by m1/m2. The m1 is to be replaced by the smallest
identifying number and the m2 by the largest one, as shown in Figure 3-31.

Sequence of Input Labels

Q.

If an input having a single functional effect is affected by other inputs, the
qualifying symbol (if there is any) for that functional effect is 'preceded by
the labels corresponding to the affecting inputs. The left-to-right order of these
preceding labels is the order in which the effects or modifications must be
applied. The affected input has no functional effect on the element if the logic
state of anyone of the affecting inputs, considered separately, would cause
the affected input to have no effect, regardless of the logic states of other
affecting inputs.

presentation is not advantageous. In those cases, the input may be shown
once with the different sets of labels separated by solidi (Figure 3-32). No
meaning is attached to the order of these sets of labels. If one of the functional
effects of an input is that of an unlabeled input to the element, a solidus will
precede the first set of labels shown.
If all inputs of a combinational
element are disabled (caused to have
no effect on the .function of the
element), the internal logic states of
the outputs of the element are not
specified by the symbol. If all inputs
of a sequential element are disabled,
the content of this element is not
changed, and the outputs remain at
their existing internal logic states.
Labels may be factored using
algebraic techniques (Figure 3-33).

Sequence of Output Labels
If an output has a number of different labels, regardless of whether they are '
identifying numbers of affecting inputs or outputs or not, these labels are
shown in the following order:
1) If the postponed output symbol has to be shown, this comes first, if
necessary preceded by the indications of the inputs to which it must
be applied
2) Followed by the labels indicating modifications of the internal logic state
of the output, such that the left-to-right order of these labels corresponds
with the order in which their effects must be applied
3) Followed by the label indicating the effect of the output on inputs and
other outputs of the element.
Symbols for open-circuit or 3-state
outputs, where applicable, are placed
just inside the outside boundary of the
symbol adjacent to the output line
(Figure 3-34).

lines that must be connected outside the outline. However, there are cases
in which this method of presentation is not advantageous. In those cases,
the output may be shown once with the different sets of labels separated
by solidi (Figure 3-35).

Present HCMOS data sheets specify, under Recommended Operating Conditions, Input tt = 1000 ns,
(10%-90%) for VCC = 2 V. Since devices can be in the threshold region from Vil MAX = 0.3 V to
VIH MIN = 1.5 V (this translates into 750 ns), there is a potential for clocked devices to go into the wrong
state from any induced ground glitch causing double clocking of the device while in the threshold region. Note
that operation of devices with input tt = 1000 ns at VCC = 2 V will not damage the device, however,
functionality is not guaranteed for ClK inputs while in the Shift, Count, or Toggle operating modes.
Devices susceptible to the above condition are:

DESIGNER'S INFORMATION
CMOS Circuitry
The elementary CMOS building blocks are the inverter and the transmission gate. Each uses a complementary pair of
one n-channel and one p-channel enhancement-type field-effect transistor. Figures I and 2 show these together with various
logic symbols t used in this book to represent them.

Figure 1. Inverters

II
Figure 2. Transmission Gates
Logic gates are created by transistors added in parallel or series to the transistors making up the elementary inverter.
Thus the simplest gates are inverting. See Figure 3. An odd number of additional inverters are sometimes added to the outputs
of gates to make them noninverting. Basic CMOS gates usually have no more than three inputs. Arrays of gates are used
when more than three signals are ANDed or ORed.

t The various logic symbols are equivalent. The distinctive-shape fonn of the inverter and gate symbols and the "TO" fonn of the transmission gate are
usually used in the device logic diagrams. The logic inversion symbol (0) is shown at the input or the output, whichever msintsins logical consistency
with the driving output or the driven input, and this technique is used to indicate the true/complement levels of the signal as it progresses through the
circuit. For example, see Figure 7 in this section. The rectangular forms of the inverter and gate symbols and the polarity indicator (1:>0.) rePlacing the
inversion symbol are usually used in this book only in the device logic symbols. The I> indicates a high-current output.

The three-state output buffer has logic elements in the gate connections to each of the transistors in the final inverter
so that both may be turned off under the control of an enable function. Figure 5 illustrates an inverting output buffer.
The transparent latch is typically implemented as shown in Figure 6. This is the simplest form. Logic diagrams in this
book show that additional inverters may be added as buffers or to optimize timing. The true and complementary outputs
(Q and Q) may be taken off at other points. Outputs brought out to terminals are always buffered to minimize any feedback
effects. The one exception to this is the 'HCV device, which has unbuffered outputs.
Putting two transparent latches in series produces the edge-triggered D-type flip-flop. The inverters can be converted
to two-input gates to provide asynchronous set and reset functions. Figure 7 illustrates a negative-edge-triggered circuit.
Exchanging the connections of C and C produces a positive-edge-triggered version.

such as synchronous clearing, J/K inputs, and toggle enabling.
In general the logic diagrams in this book have been simplified. They are believed to correctly indicate the logic
implementation but should not be used to predict dynamic performance. Inverters existing in series may be combined or

The major advantages of high-speed CMOS can be summarized as follows:
I. The high-speed CMOS family can operate at speeds comparable to LSTTL. The high-speed CMOS family has ac

parameters guaranteed at a supply voltage of 2 V, 4.5 V, and 6 V over the full operating temperature range into
a 50-pF load (also, 150 pF for high-current outputs). Note that at the higher operating frequencies, the power
consumption is also comparable to LSTTL (Figure 9).
2. Figure 9 also shows that the high-speed CMOS family covers a wide range of applications: low power drain for
low-speed systems, and a slightly higher drain for higher speed systems.

4-8

3. Minimum system power - only the gates that are switching contribute to system power consumption. This reduces
the size of the power supply required, hence provides lower system cost and improved reliability through lower
heat dissipation.
As mentioned previously. the power consumption for an individual gate at the maximum speed is comparable to
LSTTL. However in typical systems, only a fraction of the gates are switching at the clock frequency; therefore,
significant power savings can be realized. On a system level where the individual gate switching frequencies are
distributed between zero and the system clock frequency (Figure 10), the power saved with high-speed CMOS can
be quite significant, as illustrated in Figure 11. The total system power is the area under each curve. The graph
in Figure 11 is obtained by mUltiplying the individual gate characteristics (Figure 9) by the frequency distribution
in Figure 10.
4. High-speed CMOS is ideal for battery-operated systems, or systems requiring battery back-up, because there is virtually
no static power dissipation (Figure 9).

5. Improved noise immunity over bipolar devices is due to the rail-to-rail (Vee to ground) output voltage swings.
Figure 12 illustrates the noise immunity provided by the high-speed CMOS family as it compares to the LSTTL
family. This noise immunity makes it ideal for high-noise environments. Minimum and maximum output voltages
are guaranteed at 4 rnA (6 rnA for high-current devices). If the output currents exceed these limits, the noise immunity
will be impaired. 'HCT devices have similar input noise margins to LSTTL because their inputs are TTL-voltage
compatible. The outputs of 'HCT are the same as standard 'HC outputs.

maintaining good noise immunity. Although VOHmin and VOLmax are guaranteed for output currents up to 4 rnA
(6 rnA for high-current outputs), currents up to ± 25 rnA (± 35 rnA for high-current outputs) can be obtained to
drive LEOs or relays (see Driving LEOs and Relays in this section.)

Protection Circuitry
Electrostatic discharge (ESD) and latch-up are two traditional causes of CMOS device failure. In order to protect HCMOS
devices from ESD and latch-up, additional circuitry has been implemented on the inputs and outputs.

ESD PROTECTION
ESD occurs when a buildup of static charges on one surface arcs through a dielectric to another surface that has the
opposite charge. The end effect is the ESD causes a short between the two surfaces. These damaged devices (walking-wounded)
may still pass normal data sheet tests, but will eventually fail. The unique input protection circnitry designed by Texas Instruments
provides immunity to typically 4500 V on the inputs and 3000V on the outputs, which exceeds
MIL-STD-883B, Method 3015, requirements for ESD protection (2000 V, 1.5 kll, 100 pF).
Figure 13 shows the circuitry implemented to provide protection for the input gates against ESD. The diode is forward
biased for input voltages greater than Vee + 0.5 V. The two transistors and resistor (actually one transistor diffused across
a resistor) act as a resistor-diode network against negative-going transients. As illustrated in Figure 14, the ESD protection
for the output consists of an additional diffused diode (D3) from the output to Vee. The other diodes (D I and D2) are parasitics.
For further information on handling CMOS devices, see Guidelines for Handling ESDS Devices aod Assemblies in this section.

LATCH-UP PROTECTION
Internal to most all CMOS devices are two parasitic bipolar transistors; one p-n-p and one n-p-n. Figure 15 shows the
cross section of a typical CMOS inverter with the parasitic bipolar transistors. Note that, as shown in Figure 16, these parasitic
bipolar transistors are naturally configured as a thyristor or SCR. These transistors conduct when one or more of the p-n
junctions become forward biased. When this happens, each parasitic transistor supplies the necessary base current for the
other to remain in saturation. This is known as the "latch-up" condition and could possibly destroy the device if the supply
current is not limited.

A conventional thyristor is fired (turned on) by applying a voltage to the base of the n-p-n transistor, but the parasitic
CMOS thyristor is fired by applying a voltage to the emitter of either transistor. One emitter of the p-n-p transistor is connected
to an emitter of the n-p-n transistor, which is also the output of the CMOS gate. The other two emitters of the p-n-p and
n-p-n transistors are connected to Vee and ground, respectively. Therefore, to trigger the thyristor there must be a voltage
greater than Vee + 0.5 V or less than - 0.5 V and there has to be sufficient current to cause the latch-up condition.
Latch-Up cannot be completely eliminated! The alternative is to impede the thyristor from triggering. Texas Instruments
has improved the circuit design by adding four additional diffusions or guard rings alternately connected to Vee and ground
as shown in Figure 17. The guard rings provide isolation between the device pins and any p-n junction that is not isolated
by a transistor gate. All internal p-n junctions are separated by two guard rings. Tests have shown effective latch-up protection
ranges from 450 rnA to greater than 1 A at 25°C, and typically greater than 250 rnA at 125°C.

Fan-Out and Capacitance Loading Effects
High·Speed CMOS is capable of up to 10 LSITL loads from a single standard output. or 15 loads from a high-current
output. From the dc values in the individual data sheets. the fan-out of high-speed CMOS devices is unlimited for all practical
purposes. However. from an ac point of view. there is a definite limit to the fan-out. The limiting constraint is the input rise time.
With a worst-case model. about 15 pF of capacitance is associated with the input of a high-speed CMOS device (10 pF
from the device itself plus 5 pF of stray capacitance; typically. the input capacitance is 3 pF for all devices except the transceivers.
which are 6 pF). The input resistance. 11. and the output resistance. roo can be approximated with the following equations

For a fan-out of n high-speed CMOS devices, the input capacitance will be (n x 15) pF (capacitances are in parallel).
When the driving device switches its output from the low level to the high level, the input capacitance of all devices in the
fan-out must be charged up and reach VIHmin within 500 ns (the recommended rise time). Therefore,

where

R= 50 ()
C= (15 x n) pF
t= 500 ns
n = number of devices in the fan-out

Taking the natural log of both sides:
-tlRC = In(1 - VIHminIVOHtyP)
Substituting in the appropriate values and solving for n indicates that the maximum fan-out of high-speed CMOS devices
is approximately 505. Alternately, solving for t in terms of n shows that each high-speed CMOS device added to the fan-out
will increase the propagation delay from input of the driving device to the input of the driven devices by about 0.989 ns.
This corresponds to approximately 0.066 ns/pF of added delay. Table 2 contains typical values of fan-out and capacitive
loading effects at different values of Vee.

The power dissipation of high-speed CMOS devices can be separated into three components: (1) quiescent power dissipation,
PQ; (2) transient power dissipation, I>r; and (3) capacitive power dissipation, PC. The total power dissipation is the sum
of the three components, PQ + I>r + Pc.
The quiescent power is the product of Vee and the quiescent current, Icc. The quiescent current is the reverse current
through the diodes that are reverse biased. This reverse current is generally very small (on the order of a few nA), which
makes the quiescent power almost insignificant. However, for circuits that are in static conditions for long periods of time,
the quiescent power becomes a factor to be considered.

4-14

The transient power is due to the current that flows only during the time the transistors are switching from one logic
level to the other. During this time both transistors are partially on (one turning off, the other turning on), which produces
a low-impedance path between vee and ground and results in a current spike. The rise (and fall) time of the input signal
has a direct effect on the duration of the current spike. This is because the faster the input signal goes through the transition
region, the less time both transistors are partially on. The transient power is dependent on the characteristics of the transistors,
the switching frequency, and the rise time of the input signal. This component can be calculated using the following equation:

where
Cpd = power dissipation capacitance (specified on each data sheet)

Vee = supply voltage
fj = input signal frequency
Additional capacitive power dissipation is caused by the charging and discharging of the external load capacitance and
is dependent on the switching frequency. To calculate this power, the following equation may be used:

where
CL = external (load) capacitance

Vee = supply voltage
fo = output signal frequency
'HCT POWER DISSIPATION
'HCT devices are primarily used to interface TTL output signals to high-speed CMOS inputs. To make the inputs of
the 'HCT devices TTL-voltage compatible, the input transistor geometries were changed. This increased the power consumption
compared to the equivalent 'HC device, however 'HCT still provides a considerable savings in power over TTL. The increase
in power consumption is due to the fact that the TTL input levels cause both transistors in the transistor pair to be partially
turned on. Included in the electrical characteristics chart for 'HCT devices is a parameter AlCC, which enables the designer
to compute how much additional current the 'HCT device draws per input when at a TTL voltage level.

Power Supply Decoupling
When an SN54HC174HC gate switches, there is a brief period (on the order of a nanosecond) during which both transistors
in the gate output buffer (Figure 19) are partially on. In this interval, the device draws a substantial supply current, producing
a current spike on the Vee and ground leads to the gate. This spike may exhibit dildt as high as 5000 A/s. These spikes
will react with the distributed inductance of the supply wiring to produce significant voltage transients on Vee and ground
unless adequate supply decoupling is provided. These transients, if allowed, will couple directly into the gate outputs, which
in normal usage switch from rail-to-rail.

Figure 20 illustrates a circuit for testing the effectiveness of decoupling. In this test circuit, the Vee and ground connections
consist of two parallel runs of one-eighth inch copper on a G-IO epoxy-glass circuit board. As a O.OI-,.F decoupling capacitor
between Vee and ground is physically moved away from a driven gate in 1.5-inch increments, Vee transients increase as
shown in Figure 21.

Connecting Unused Inputs

Unused inputs should be tied to Vee or ground to prevent the input from floating. If left to float, the power consumption
of the device will increase.

Matching
Another factor to consider when designing with high-speed CMOS is the VOHlnin-to-Vr matching. This is important
when the VOHmin of the driving device exceeds the Vee + 0.5 V of the driven device. If this occurs, the ESO protection
diode on the inputs will be forward biased. At this point, the driving device will attempt to "power-up" the driven device's
power supply. No damage will occur to the driven device, provided the current flowing through the diode does not exceed
20mA.

Powering Up/Down Sequence for High-Speed CMOS
To avoid any possible damage and reliability problems to the high-speed CMOS devices when applying power, the following
steps should be followed:
I. Connect ground
2. Connect Vee
3. Connect the input signal
When powering down a high-speed CMOS device, follow the above steps in reverse order.

High-Speed CMOS Interfacing
INTRODUCTION
The High-Speed CMOS logic family from Texas Instruments contains a broad spectrum of SSIIMSI functions. Within
this family are TTL functions, HCT devices, HC4000 series, and an HCU device. I Entire CMOS systems may be implemented
using this logic family. There is also a broad range of CMOS-system to non-CMOS-system interfaces that need to be considered.
The design engineer will inevitably encounter these interfaces. To develop the necessary interfaces, a thorough understanding
of data sheet parameters of both systems and an organized approach is recommended. This report uses basic examples to
present one possible approach to the SN54174HC interface solution.
There are two types of interfacing that must be considered: (1) interfacing CMOS system signals to non-CMOS systems
and (2) interfacing non-CMOS system signals to CMOS systems. The first type requires an understanding of the CMOS
output parameters and the non-CMOS input parameters and vice versa for the second type. In both cases, a model of the
inputs and outputs of both systems may be useful.

GENERAL INTERFACING SOLUTION

0';:;

An interfacing problem arises when the output logic levels and/or the current requirements of the driving system (or
device) are different from the input logic levels and/or the current requirements of the driven system (or device). When
determining the compatibility of the systems (or devices), the most important system/device parameters are VIH, VIL, VOH,
VOL, IIH, IlL, IOH, and VOL·

Figure 22 is the voltage transfer characteristic of a typical unloaded inverter showing the various input and output voltage
parameters. Loading the output of the inverter will tend to lower VOH and raise VOL. The tables of electrical characteristics
specify minimum VOH and maximum VOL for various loads.

Noise Margin

C\)

C
There are two noise margins to be considered: the low-voltage noise margin and the high-voltage noise margin. The
voltage difference between VILmax of the driven system/device and VOLmax of the driving system/device is the low-voltage
noise margin. The voltage difference between VOHmin of the driving system/device and VIHmin of the driven system/device
is the high-voltage noise margin (Figure 23).
I HCT devices are explained later. The HC4000 series devices are pin-for-pin functionally compatible, but not electrically compatible, with the older meta1gate CMOS devices. The HCU device is unbuffered.

4-17

It is desirable to have the noise margin as large as possible and the uncertain region (the difference between Vrnmin and
VJLIlIIlX) as sma1l as possible. When an input voltage falls into the uncertain region, we do not know how the output in conjuction
with other inputs driven by that output will respond. The problem with small noise margins is that any noise on the output
of the driving system or device will cause the signal to fall into the uncertain region and possibly cause a bit error in the
system. There are various sources of noise in digital systems. Three possible internal sources are inductive and resistive
drops, capacitive coupling from another logic node, and mutual inductance with another logic node. Radio signals are possible
external sources of noise.

Driving Gate Output Model
Figure 24 shows the model of a driving gate derived from the data sheet specifications. VOH(n1) (nl = no load) is the
high-level output voltage expected when the output gate is unloaded. VOL(n1) is the low-level output voltage expected when
the output gate is unloaded. The values for these two voltages are usually not given on the data sheets. As a rule of thumb
for MOS devices, the output switches between the power rails VOH(n1) = Vee and VOL(n1) = GNO; for bipolar devices

The inverter, which is powered by a separate voltage source, serves to restore the oscillator output voltage to 5 V peak-topeak. This function is required, because the 'HCOO switches from rail-to-rail (as do all HC devices). The magnitude of the
oscillator output voltage is thus dependent on VC. The l00-ldl resistor across the inverter provides bias such that operation
will be within the linear operating region of the gate. The capacitor serves to ac-couple the oscillator to the inverter .

Drivers for LEDs and Relays
INTRODUCTION
SN54174HC devices are capable of sinking or sourcing up to 25 rnA (35 rnA for high-current devices) per gate. As the
device sinks or sources more current, VOHmin or VOLmax levels will begin to fall or rise respectively.
Because of these characteristics, SN54174HC devices can be used to drive LEOs and relays.

DRIVING LEOs

Multiple gates can be connected in parallel to increase the current sinking or sourcing capability of SN54174HC devices.
Figure 41 shows two 'HC04 gates connected in parallel for relay driver application.
Precautions should be taken to prevent one gate from "hogging" the current. SmaIl resistors (typically 50 0) in series
with the output gate will limit the possibility of "current hogging" by anyone gate.
In all applications in which the SN54174HC output is required to source or sink substantial current (6 rnA to 25 rnA),
particular attention should be paid to providing adequate power supply decoupling for the driving device.

SNS4HC/SN74HC Interchangeability Guide
INTRODUCTION
The following has been prepared as a guide to interchanging devices from other logic families, both bipolar and CMOS,
with those from the SN54HC/SN74HC family. This is not intended to be a comprehensive guide since interchangeability
can depend on many factors, and only careful data sheet comparisons can provide definitive answers. The considerations
listed below are based upon information accumulated in answering a large number of inquiries in this area.
First, a brief review is given on each logic technology, and second, discussion is given on the various aspects involved
in attempting to interchange that technology with the SN54HC/SN74HC family.

4-28

TIL: Transistor-Transistor Logic
TTL is the generic name for several bipolar families that have evolved over the past 20 years. Low-Power Schottky
(LSTTL) is the most widely used bipolar logic family today. Other families, e.g., Schottky (STTL), Advanced Schottky
(ASTTL or AS), and Advanced Low-Power Schottky (ALSTTL or ALS) are also used, depending on the speed versus power
performance required by a given system design.

4000 Series: Metal-Gate CMOS Logic
The device type numbers in this series have a variety of prefixes, although "CD" is probably the most widely recognized.
The suffix "B" is frequently used, indicating an improvement over the original family, i.e., buffered outputs and typical
output sink and source current capabilities of ± 1 rnA. This logic family became popular because it offered very low power
consumption, even though it is slower than TTL with a typical operating frequency of about 5 MHz, has a low level of ESD
protection, and is latch-up prone.

40HOO Series: Metal-Gate CMOS Logic
This series was designed to overcome the speed limitations of the original 4000 family. Even though these devices are
somewhat faster, they are still slow when compared to LSTTL.

74COO Series: Metal-Gate CMOS Logic
The distinguishing feature of this family is that the pinouts correspond to those of TTL, making interchangeability easier.
The devices, however, exhibit many of the same speed/power limitations as those of the 4000 series. The fan-out is typically
higher than the 4000 series, however, with typical output sink and source capabilities of ± 1.75 rnA.

74SCOO Series: Silicon-Gate CMOS Logic
This series was the forerunner to the SN54HC/SN74HC family, or more closely, to the SN54HCT/SN74HCT family.
The 74SC family was designed to overcome many of the 4000 series deficiencies, particularly the slower speed and the lower
drive capability.
Note: The "SC" designation should not be confused with that of Texas Instruments new Standard Cell family
(SN54SC/SN74SC series).

INTERCHANGEABILITY CONSIDERATIONS

The use of antistatic chemicals (antistats) should be a supplemental part of an overall organized ESD program. Any antistatic
chemical application shall be considered as a means to reduce or eliminate static charge generation on nonconductive materials
in the manufacturing or storage areas.
The application of any antistatic chemical in a clean room of class 10,000 or less shall not be permitted. Accordingly,
any user of antistatic solutions must consider the following precautions:

1. Do not apply antistatic spray or solutions in any form to energized electrical parts, assemblies, panels, or equipment.
2. Do not perform antistatl'c chemical applications in any area when bare chips, raw parts, packages, and/or personnel
are exposed to spray mists and evaporation vapors.

4-33

The need for initial application and frequency of reapplication can only be established through routine electrostatic voltage
measurements using an electrostatic voltmeter. The following durability schedule is a reasonable expectation.
I} Soft surfaces (carpet, fabric seats, foam padding, etc.): each 6 months or after cleaning, by spraying.
2} Hard abused surfaces (floors, table tops, tools, etc.): each week (or day for heavy use) and after cleaning, by
wiping or mopping.
3} Hard unabused surfaces (cabinets, walls, fixtures, etc.): each 6 months or annually and after cleaning, by wiping
or spraying.
4} Company-furnished and maintained clothing and smocks: after each cleaning, by spraying or adding antistatic
concentrate to final rinse water when cleaned.
The use of antistatic chemicals, their application, and compliance with all appropriate specifications, precautions, and
requirements shall be the responsibility of the Area Supervisor where antistatic chemicals are used.
ESD Labels and Signs in Work Areas
ESD caution signs at work stations and labels on static-sensitive parts and containers shall be consistent in color, symbols,
class, and voltage sensitivity identification, and appropriate instructions. Signs shall be posted at all work stations performing
any handling operations with static-sensitive items. These signs shall contain the following information.
CAUTION
STATIC CAN DAMAGE COMPONENTS
Do not handle ESDS items unless grounding wrist strap is properly

worn and grounded. Do not let clothing or plain plastic materials
contact or come in close proximity to ESDS items.

II

Labels shall be affixed to all containers containing static-sensitive items at a place readily visible and proper for the intended
purpose. Additionally, labels must be consistently placed on containers and packages at a standard location to eliminate
mishandling. Use only QC accepted and approved signs and labels to identify static-sensitive products and work areas. The
use of ESD signs and labels, and their information content shall be the responsibility of the Area Supervisor to assure consistency
and compatibility throughout the static-sensitive routing.
Relative Humidity Control

.

Since relative humidity has a significant impact on the generation of static electricity, when possible, the work area should
be maintained within the following relative humidity ranges: incoming/assembly/test/storage 50%-65 % (ref. Ashrae, 55-74),
within ± 5 % to avoid static voltage monitor variations.

I»

A work station with a conductive work surface connected to ground through a I Mil ± 10% resistor, a grounding wrist
strap with the ground wire connected to the conductive work surface, and an ionizer constitute a static-free work station
(Figure 42). An operator is properly grounded when the wrist strap is in snug (no slack) contact with the bare skin, usually
positioned on the left wrist for a right-handed operator. The wrist strap must be worn the entire time an operator is at a
static-free work station. The operator should first touch the grounded bench top before handling static-sensitive items. This
precaution should be observed in addition to wearing the grouding wrist strap. If possible, operators should avoid touching
leads or contacts even though grounded .

:::s

CAUTION
Personnel shall never be attached to ground without the presence
of the I Mil ± 10% series resistor in the ground wire.

4-34

An operator's clothing should never make contact or come in close proximity with static sensitive items. They must
be especially careful to prevent any static-sensitive items (being handled) from touching their clothing. Long sleeves must
be rolled up or covered with antistatic sleeve protector banded to the bare wrist which shall "cage" the sleeve at least as
far up as the elbow. Only antistatic finger cots may be used when handling static-sensitive items.
Any person not properly prepared, while at or near the work station, shall not touch or come in close proximity with
any static-sensitive items. It is the responsibility of the operator and the Area Supervisor to ensure that the static-free work
area is clear of unnecessary static haiards, including such personal items as plastic coated cups or wrappers, plastic cosmetic
bottles or boxes, combs, tissue boxes, cigarette packages, and vinyl or plastic purses. All work-related items, including
information sheets, fluid containers, tools, and parts carriers must be those approved for use at the static-free work station.

GENERAL HANDLING PROCEDURES AND REQUIREMENTS
1. All static-sensitive items must be received in an antistatic/conductive container and must not be removed from
the container except at static-free work station. All protective folders or envelopes holding documentation (lot
travelers, etc.) shall be made of nonstatic-generating material.
2. Each packing (outermost) container and package (internal or intermediate) shall have a bright yellow warning
label attached, stating the following information or equivalent:

CAUTION

ELECTROSTATIC
SENSITIVE
DEVICES
DO NOT OPEN DR HANDLE
EXCEPT AT A
STATIC·FREE WORKSTATION

The warning label shall be legible and easily readable to normal vision at a distance of 3 feet.
3. Static-sensitive items are to remain in their protective containers except when actually in work at the static-free
station.
4. Before removing the items from their protective container, the operator should place the container on the conductive
grounded bench top and make sure the wrist strap fits snugly around the wrist and is properly plugged into
the ground receptacle, then touch hands to the conductive bench top.
5. All operations on the items should be performed with the items in contact with the grounded bench top as much
as possible. Do not allow conductive magazine to touch hard grounded test gear on bench top.
6. Ordinary plastic solder-suckers and other plastic assembly aids shall not be used.
7. In cases where it is impossible or impractical to ground the operator with a wrist strap, a conductive shoe strap
may be used along with conductive tile/mats.
8. When the operator moves from any other place to the static-free station, the start-up procedure shall be the
same as in PREPARATION FOR WORKING AT STATIC-FREE WORK STATION.
9. The ionizer shall be in operation prior to presenting any static-sensitive items to the static-free station, and shall
be in operation during the entire time period the items are at the station.
10. "Plastic snow" polystyrene foam, "peanuts," or other high-dielectric materials shall never come in contact
with or be used around electrostatic sensitive items, unless they have been treated with an antistat (as evidenced
by pink color and generation of less than ± 100 volts).
11. Static-sensitive items shall not be transported or stored in trays, tote boxes, vials, or similar containers made
of untreated plastic material unless items are protectively packaged in conductive material.

SPECIFIC HANDLING PROCEDURES FOR STATIC-SENSITIVE ITEMS
Stockroom Operations
1. Containers of static-sensitive items are not to be accepted into stock unless adequately identified as containing
static-sensitive items.
2. Items may be removed from the protective container (magazine/bag, etc.) for the purpose of subdividing for
order issue only by a properly grounded operator at an approved static-free station as defined in FACILITIES
FOR and PREPARATION FOR WORKING AT STATIC-FREE WORK STATION.
3. All subdivided lots must be carefully repackaged in protective containers (magazine/bag, etc.) prior to removal
from the static-free work station and labeled to indicate that the package(s) contain static-sensitive items. If it
is suspected that a static-sensitive item is not adequately protected, do not transfer it to another container, return
it to the originator for disposition unless the originator is a Customer. In that case, the QC Engineer should
contact the Customer and negotiate an appropriate disposition.
4. It is the responsibility of the Stockroom Supervisor to ensure that all personnel assigned to this operation are
familiar with handling procedures as outlined in this specification. A copy of this specification is to be posted
in the vicinity so that it is accessible to the operators. Stock handlers and all others who might have occasion
to move stock are to be instructed to avoid direct contact with unprotected static-sensitive items.
Module and Subassembly Operations
1. Static-sensitive items are not to be received from a stockroom, kitting, or machine insertion area unless received
in approved static-protective packaging, and properly labeled to indicate that its contents are static sensitive.
2. All single station, progressive line manual assembly operators, and visual inspectors prior to wave soldering
operations are to be properly grounded with a grounding wrist strap when handling static-sensitive items.
3. Progressive lines used as single stations where operators will be working on a mix of boards, both static-sensitive
and nonstatic-sensitive, will require that all operators working on the line be properly grounded. This is necessary
to accommodate the sliding of static-sensitive boards along the assembly bench or across positions not engaged
in the assembly of this type board.
4. It is the responsibility of the Area Supervisor to ensure that all personnel handling static-sensitive items are
familiar with this procedure and fully aware of the damage or degradation of these units in the event of
noncompliance. A periodic inspection should be made using an electrostatic voltmeter to assure that the staticfree stations are in proper working order and to ensure that operators are wearing grounding wrist straps properly
(snugly in contact with bare skin).

INTRODUCTION

To aid in interfacing TTL system signals to High-speed
CMOS (HCMOS) systems, Texas Instruments has
included in its HCMOS family a subfamily of 'HCT
devices. While functionally identical to their 'HC
counterparts, the input voltage thresholds of the 'HCT
subfamily are designed to recognize TTL-level voltages.
The output voltages of the 'HCT devices are identical to
those of the 'HC devices, i.e., rail-to-rail.
TTL to HCMOS Interface
There is an incompatibility between TTL output
voltages and the HCMOS input voltages, specifically the
VOH of TTL and VIH of HCMOS. To overcome this
incompatibility there are at least three methods to
interface TTL signals to HCMOS. The first method is to
use the HCMOS subfamily 'HCT. The second method
involves using a pull-up resistor to pull-up the VOH of the
TTL gate to a voltage that is greater than the VIH of the
HCMOS device. The final method is to use a voltage level
shifter.
Using the 'HCT devices is by far the easiest. The
'HCT devices were designed specifically for this type of
application. Use of 'HCT devices enables the system
designer to reduce the number of discrete components (no
pull-up resistors), and receive the benefits of HCMOS.
Using pull-up resistors to interface the TTL signals
to HCMOS requires the system designer to calculate the
range of acceptable values for the pull-up resistor. The
lower limit is determined by the current sinking capability
of the driving gate.

VCC - VOL max

Where n is the number of gates in the fanout.
Determining the upper limit of the pull-up resistor is
not as simple. The upper limit must satisfy two constraints.
The first is limited by the input current of the driven gate.
Since the driven gate is HCMOS the input current will be
extremely small (on the order of a nanoamp).
VCC - VIH min

Rp max =
Where n is the number of gates in the fanout
In this equation, IOH of the driving gate has been
omitted because all the current is being supplied through
the pull-up resistor. For the second constraint, Rp max is
derived through the following equation:

Where
t is the maximum rise time requirement of 500 ns
C is the input capacitance of 3 pF typ., 10 pF max
Rearranging the equation:

C In(l- VIHlVecJ

The upper limit to the pull-up resistor will be most
influenced by the rise time requirement of the input signal.
The larger the resistor, the longer the rise time of the input
signal. This will adversely affect the propagation delay of
the input signal. By reducing the value of the pull-up
resistor, the rise time of the input signal will benefit, but
the current through the pull-up resistor will be increased.
This will have an adverse effect on the system power
consumption.
The last method uses a voltage level shifter to make
the TTL signals HCMOS compatible. This method has a
major drawback, in that the level shifter performs no logic
function. Therefore additional logic will have to be added
to the system, increasing the board area.
From a designer's point of view, using 'HCT devices "';::;
to interface TTL signal to HCMOS is by far the easiest CO
and most efficient method. 'HCT devices provide the
voltage-level shifting and the logic function in a single o
chip. In addition, there is no need to compromise between c:
the input signal rise time and the pull-up resistor current.

'HCT Operating Voltages
The 'HCT devices have a limited Vee operating
range due to the fact that these devices must be able to
recognize TTL-level voltages. Although the 'HCT devices
will operate from 2 V to 6 V (same as 'HC devices), there
are two major disadvantages in addition to the fact that
there are no guaranteed specifications for operation
outside the 4.5 V to 5.5 V Vee range. First, the noise
margins, especially the low-voltage noise margin, will
become smaller and smaller as t.he Vee is decreased.
Second, the input voltage thresholds will no longer remain
TTL-level compatible, which is the primary function of
'HCT.

'HCT Noise Immunity
Noise immunity is an important criterion in system
designs. Noise immunity. has two components: highvoltage noise margin and low-voltage noise margin. Highvoltage noise margin is the voltage difference between the
guaranteed VOH of the driving gate and the guaranteed V
IH of the driven gate. Low-voltage noise margin is the
voltage difference between the guaranteed VIL of the
driven gate and the guaranteed VOL of the driving gate.
These two components of noise immunity are illustrated in
Figure 1.
It is desirable to have both noise margins as large as
possible, and the area in between (the uncertain region) as
small as possible. If the noise margins are not large
enough for a particular application. noise from any
internal or external source will cause the input/output
signal to fall into the uncertain region and possibly cause a
bit error to enter the system. Three possible sources of
internal noise are inductive and resistive drops, capacitive
coupling from another logic node, and mutual inductance
with anotitel logic node. External noise sources are mainly
radio signals.
Figure 2 illustrates the guaranteed noise margins of
'HC, 'HCT and 'LS devices. As can be seen, 'HC devices
have high- and low-voltage noise margins of 29% and 19%
of Vcc respectively. A coinparision of these noise margins
to those of 'LS devices, shows that 'HC devices have more
than twice the guaranteed noise margins than 'LS devices.
The 'HCT devices seem to have a larger noise margins
than the 'HC devices. However, this is slightly deceiving.
The only configuration to achieve the large high-voltage
noise margin is to have the input of the 'HCT device be

driven from either another 'HCT device or an 'HC device.
Although this may be advantageous for noise margins, the
'HCT device is in the wrong application. The 'HCT
devices are designed to interface from TTL-level signals to
HCMOS-Ievel signals. Using the 'HCT device in its
appropriate application, i.e., an 'HCT device driven by an
LSTTL device, the noise margins will be identical to those
of 'LS. The 'HC noise margins allow a greater magnitude
of noise within the system without causing errors. This is
very beneficial for applications in high noise
environments. Figure 3 illustrates the noise margins of
'HC and 'HCT with respect to the devices' actual switching
threshold voltages. The switching threshold voltage is the
voltage to which the input transistors "compare" the
voltage on the input pin. If the input voltage is greater
than the threshold voltage, then the input transistors
recognize this input as a logic 1. If the input voltage is less

than the threshold voltage, the input transistors recognize
the input as a logic O. This figure again presents slightly
deceiving 'HCT noise margins for the same reasons as
previously explained. Note that while both 'HC and 'HCT
noise margins have been enlarged, the 'HC noise margins
approach the ideal situation, 50% of Vee. 'HCT, on the
other hand, although exhibiting a larger high-voltage noise
margin than 'HC, has a smaller low-voltage noise margin.
In an 'HC system, both the high- and low-voltage noise
margins are almost 50% of Vee, and consequently, in an
actual system environment, there is very little possibility
for noise to introduce a bit error into the system.
For the best overall noise margins in a system, a
combination of 'HCT and 'HC devices are used. The
'HCT devices are used to interface the TTL-level signals
to the HCMOS. The 'HC devices are for the other parts of
the system not involved with TTL-level input signals.
'RCT Power Consumption
To enable the 'HCT devices to recognize the TTL
logic levels, the input transistor pair geometries were
altered. In an 'HC device, the width of the gate of the
input P-channel transistor is approximately twice the width
of the gate of the N-channel transistor. For 'HCT devices,
this configuration has been changed so that the N-channel
transistor gate is approximately seven times wider than the
P-channel transistor gate. This is illustrated in Figure 4. It
should be noted that the gate width is the parameter that
changes, not the gate length, which remains 3 fLm in both
the 'HC and 'HCT devices. The end result achieved with
this new input structure configuration is the capability of
turning on the N-channel transistor at a lower input
voltage.

To achieve the above results, however, trade-offs are
required. A major advantage of the HCMOS structure is
its low-power consumption. Because of the larger Nchannel transistor in the input structure of 'HCT device,
more supply current is drawn by these devices. This is due
to the N-channel transistor not completely turning off
when a TTL-level voltage is applied to the input, an effect
especially apparent when a TTL VOL level is applied. To
aid the system designer in using 'HCT devices, Texas
Instruments includes in the dc tables of the 1984 HighSpeed CMOS data book for 'HCT devices a parameter,
boIce, which is the additional supply current drawn by the
device when one input is at the specified TTL-level voltage
rather than at 0 V or Vee. Typical and maximum values
are specified.
Figure 5 illustrates this increase in supply current by
comparing ICC for a 'HCT243 with TTL-voltage levels on
one input versus TTL-voltage levels on four inputs. For
this test, each output is loaded with a 50-pF capacitor and
the input signal was a 0.5-V to 2.4-V peak-to-peak square
wave with a 50% duty cycle. Figure 6 shows the supply
current drawn by an 'HCT243 in the same circuit but with
a O-V to 5-V square wave with a 50% duty cycle. When the
input to an 'HCT device is rail-to-rail, the 'HCT device
draws no more current than is drawn by an 'HC device
under the same conditions. Figure 7 shows a comparison
of supply current drawn by an 'HCT device when
subjected to TTL-voltage level inputs versus rail-to-rail
inputs, with all four inputs being switched simultaneously.
At frequencies above 5 MHz, the additional supply
current is relatively insignificant (approximately 2 rnA),
but at lower operating frequencies the difference in the
total supply current as a percentage becomes much more

significant. Because of this, the use of 'HCT devices may
not seem to be a particularly desirable solution for
interfacing TTL-level voltages to HCMOS. The TTL-level
inputs in Figure 7 were the guaranteed VOH and VOL.
These guaranteed voltages are for a specified current
being sin ked or sourced by the TTL device. In fact,
because 'HC and 'HCT devices are voltage level sensitive
(Le., they require no input current), the VOH of the
driving TTL gate, when driving HCMOS, will be much
higher than the guaranteed voltage. Typically, the VOH of
an 'LS gate will be approximately one VBE plus a
VCE(sat) below Vee, and the VOL of an 'LS gate will be
approximately one VeE(sat) above ground. Due to this,

4-44

the additional Iec drawn by the 'HCT gate will not be as
significant.
By comparison, an alternative method for
interfacing TTL signals to 'HC is the use of pull-up
resistors (See Note I), but here again trade-offs will have
to be made. Using larger value pull-up resistors decreases
the amount of additional supply current drawn, but
degrades the rise time of the input signal to the 'HC gate,
limiting the use of this method in high-speed systems.
Decreasing the value of the pull-up resistor will shorten
the rise time, but will cause the supply current to increase.
The best overall solution is the use of 'HCT devices, which
reduces also the number of discrete components required
in the circuit.
Note 1: A complete description on how to interface TIL systems to
HCMOS systems, and vice versa, is given in the Texas Instruments
High-Speed Silicon-Gate CMOS data book.

Overall, the 'HCT devices provide a simple and
efficient means for a system designer to interface TTLlevel voltages to HCMOS systems, and gain many of the
advantages of HCMOS.

VIL-IIL and VIH-IIH characteristic of the driven gate as
illustrated in Figure 8. For switching from a logic I to a
logic 0, the next step is to draw a line from the VOH point
(Point to in Figure 9) on the Va axis toward the output
characteristic of the driving gate. The slope of the line is
- liZ, where Z is the impedance of the transmission line.
At the intersection of the - liZ line and the output

toward the Va axis. The slope of this line is + liZ. the
second Va axis intersection (Point t2 in Figure 9) or the
intersection with the input characteristic, is the voltage seen
by the driven gate. If this voltage is less than the switching
threshold voltage, then incident wave switching will be
achieved. If the second Va axis intersection is not less than
the switching threshold voltage then reflected wave switching
will occur.

Propagation delays
One other drawback to the use of 'HCT is the added
propagation delay. Although there are no additional
stages in an 'HCT device, compared to an 'HC device, the
relatively small p-channel device has more difficulty
charging and discharging the capacitance associated with
the relatively large n-channel device. This results in an
increase in propagation delay of approximately 1 to 2 ns
for each 'HCT input.
'RCT Bergeron Analysis
Within a logic system, It IS important to know
whether or not a signal sent from one subsystem will cause
incident wave or reflected wave switching on the input of
the receiving subsystem. The incident wave or reflected
wave switching issue is important because the transition
times of the outputs are as fast or faster than the
propagation times within the system's buses, causing the
system buses to have characteristics similar to those of
transmission lines. This in conjunction with impedance
discontinuities, will cause signal reflections on the system's
buses. These signal reflections may produce additional
propagation delays, ringing, and overshoot.
Due to the fact that digital logic devices do not have
linear input and output characteristics, the basic
transmission line equations are not easily applied. What is
needed is a simple method that will produce reasonably
accurate results. Using Bergeron diagrams, the digital
logic interconnections can be analyzed through a simple
graphics technique.
To illustrate the graphical technique, we are using an
example of an 'ALSOO driving an 'HCT245 through a 30-0
transmission line. The first step is to plot the VOL-IOL
and VOH-IOH characteristics of the driving gate and the

For switching from logic 0 to . logic 1 the same

VOL point (Point to in Figure 10) on the Va axis toward
the output characteristic (Point t1 on Figure 10). The same
criterion for incident wave switching is used; the second
Vo axis intersection (Point 12 on Figure 10) must be
greater than the switching threshold voltage.
In the preceding example, the switching threshold
voltage was used as the criterion for incident versus

Using the same analysis method, it can be seen (see
Figure 11) that an 'HCT device driving another 'HCT
device will have difficulty achieving incident wave
switching on low-impedance transmission line (see the
load lines for the 30-D line for a logic 1 to logic
transition). Because 'HC and 'HCT have the same output
characteristics, and because 'HC has its thresholds at a
higher voltage, the 'HC device can achieve incident wave
switching on the low-impedance line.
In order to maintain the ability to drive lowimpedance transmission lines throughout the system,
'HCT devices should be used only at the TTL interface,
and 'HC devices should be used elsewhere.

Summary
The major application of 'HCT is to provide the
interface between TTL signals and HCMOS. Due to the
fact that the input transistor pair geometries were altered
to provide TTL compatibility, there were some inherent
drawbacks. For this reason 'HCT should be used only at
the TTL interface, and elsewhere 'HC should be used.
This will result in optimum system performance.
As the HCMOS technology progresses, more and
more systems will be designed in Silicon-Gate CMOS,
especially with more LSI functions being offered (e.g.,
memories and microprocessors). Consequently the trend
is expected towards .CMOS levels on the interconnecting
buses. Once this occurs, the need for 'HCT functions will
diminish rapidly.

INTRODUCTION
There is considerable confusion over the maximum input and
output voltage specifications for the '74HC devices. Basically
there are two questions: what exactly do the specifications
mean; and why do different manufacturers have different
specifications? This report answers these questions by
considering the input and output structures of '74HC devices.

INPUT STRUCTURES
The maximum input and output voltages and currents
that can be applied to a '74HC device are primarily
determined by the ESD structures. Figure I illustrates the
input structure used on Texas Instruments SN74HC family,

'NPUTP'N~f
5~-3.;~~Am
Figure 1. TI's ESD Input Protection Circuitry

and Figure 2 illustrates the structure commonly used by other
manufacturers of the '74HC product line. It is beyond the
scope of this report to discuss the relative merits of each
structure from an ESD protection standpoint. Therefore, how
the specifications are affected by each structure is discussed.

Figure 2. Other MllUufacturers' ESD Input
Protection Circuitry
From Figure I it can be seen that in the Texas
Instruments' input structure, a voltage in excess of Vee will
be clamped to a VBE above Vee by the protection diode.
A voltage below ground will be similarly clamped to a VSE
below ground, this time by the base·emitter junction of the
distributed n-p-n transistor. Therefore, when the input voltage
is taken outside the Vee or ground rails, the characteristics
of a forward-biased diode can be seen. Thus, it is meaningless

to specify a maximum input voltage (either positive or
negative). It is the current through the forward-biased diode
which is the limiting parameter. If this current becomes too
large, there is the possibility of damage to the device either
from blowing the bond wire or excessively heating the diode
(or transistor).
The JEDEC committee does indeed recommend a
maximum input voltage of Vee + 0.5 V (in the positive
direction) and -0.5 V (in the negative direction). This
parameter can best be regarded as an indication that the
protection devices are present rather than a "traditional"
maximum voltage specification. For this reason Texas
Instruments does not include this parameter on the data sheet.
The key parameter included on the Texas Instruments
data sheet is the input diode current, and this diode current
corresponds to the JEDEC recommended limit. The
parameter, 11K, has a maximum value of ±20 rnA, which
is the maximum current that can be allowed to flow
continuously through the input protection structures. The
peak value of this current has a much higher value and is
usually limited by the degree of latch-up protection existing
on the input.
The structure shown in Figure 2 is different from the
Texas Instruments protection circuitry. In this configuration
a polysilicon resistor is located in series with the protection
diodes. The affect of this resistor on the input voltage
parameters is to limit the current flowing through the
protection diodes. The existence of this diode is the reason
why some manufacturers have chosen to specify the
maximum input voltage as Vee + 1.5 V (positive) and
- 1.5 V (negative). Since the input voltage corresponds to
the VBE of the protection diode plus the IR drop across the
resistor, this maximum input voltage specification ensures
the current flowing through the input structure is limited to
the JEDEC 20 mA value.

The output structure is illustrated in Figure 3. In this
case it is the same for all manufacturers. Since two of the
diodes are parasitic in the output transistors, no alternative
is possible. The same considerations discussed earlier for
the inputs are true for the outputs. Therefore, the output
voltage will also be clamped to a VBE above the supply and
below the ground rails. A specification similar to the input
diode current exists for the output diode current (10K). The
maximum value is also ± 20 mA, corresponding to the
JEDEC recommendation. JEDEC also has a recommended
maximum output voltage specification of Vee + 0.5 V or
-0.5 V. The manufacturers use these same limits when
output voltages are specified. As with the maximum input
voltage specification, this parameter has limited usefulness.

.
Under certain transient load conditions, particularly
when driving high capacitances or unterminated transmission
lines, undershoot or overshoot can Occur. The output
impedance of the SN74HC family is approximately 50 {} for
standard outputs, and approximately 25 {} for high current
outputs (Figure 5). This output impedance is symmetrical,
having about the same slope regardless of whether the output
is in a high or a low state. This alone overcomes many of
the transient problems experienced with bipolar circuits, since
the SN74HC family's output impedance tends to damp out

APPLICATION CONSIDERATIONS

Now that the input and output structures and the
parameters associated with them have been discussed, their
effects in an application will be examined. It is convenient
to consider transient effects and steady-state effects
individually.
In the steady state, if two systems or subsystems are
interconnected, and each has its own power supply, the
protection structures limit the difference between the two
supply voltages. If this difference exceeds a VBE, then
excessive supply current will be drawn from the higher of
the two supplies through the input protection structures of
devices powered from the other supply (Figure 4). If this

current is not limited to a safe value, there is the potential
to damage the devices. However, in almost all applications,
the increase in supply current will be undesirable. It should
be noted in this case that neither of the two input structures
offers an advantage over the other as the output protection
structures limit the difference in supply voltage. This is the
only steady-state effect likely to be of interest in most
applications. The only other possibility is that voltages may
be applied to 74HC inputs from sources external to the
system, and these voltages exceed Vee. In this case,
additional resistors will be required in series with the inputs,
regardless of the input structure used, in order to limit the
input current to a safe value. This situation should be avoided

In an HC system, if undershoot or overshoot is present
or exceeds the turn-on voltage of the protection structures,
then an excess current will flow for the same reasons
discussed. However, this time it will only be a transient
current and it is possible to exceed the maximum 11K or 10K
ratings without causing damage to the device (11K and 10K
are continuous ratings). Unfortunately there is no peak
current limit in the existing specifications. However, in
practice the maximum limit is determined by the degree of
latch-up immunity offered by the devices being used. This
is to be expected since transients of this nature are the major
cause of latch-up problems. Therefore the manufacturer's
latch-up specifications should be carefully studied to
determine how much overshoot or undershoot can be
tolerated. A review of the specifications will reveal a
considerable variation between manufacturers. Some do not
even specify any degree of latch-up suppression. For this
reason Texas Instruments developed latch-up suppression
circuitry capable of withstanding in excess of 250 mA at
25°C, or in excess of 100 mA at l25°C.
Referring to the schematics for the input protection
structures (Figures 1 and 2), it will be seen that the version
shown in Figure 2 does offer an advantage in the transient
mode of operation as the poly resistor will inhibit the current

flowing through the diodes. However, the output structures
are again the limiting parameter as the outputs are also
susceptible to the transients and are capable of latching up
under extreme conditions.
In summary, under transient conditions, external current
limiting will not be required for most applications unless
severe overshoot or undershoot is present which would result
in input or output currents comparable to the trigger currents
of the parasitic SCRs inherent in HC devices.

CONCLUSION
As a result of the use of different ESD protection
structures, manufacturers specify different absolute
maximum voltage ratings for the input of HC devices. This
difference is of little importance to the system designer. The
maximum input current is really the key input parameter
which determines whether or not a device will be damaged.
The output ESD protection structures, which are inherent
in the output transistors, set the lower limit on the maximum
voltage that can be withstood on the outputs without forward
biasing these protection structures. Such forward biasing may
result in excessive current drain or, in extreme cases, device
damage:

CMOS devices offer a designer many desirable features, the
most important one being a low power consumption.
However, in some systems a designer will find that even the
low power consumption of CMOS is insufficient to meet his
power supply constraints. Therefore, some designers will
utilize partial system power-down or multiple Vee supplies
to meet their system power requirements.
Whenever a system incorporates the lise of multiple
Vee supplies or partial power-down, the designer must take
into account several important device parameters if he is
using High-Speed CMOS (HC) or Advanced CMOS (ACL)
devices. This is necessary to avoid excessive power
dissipation and prevent damage to a device that could lead
to a degradation in the reliability of the device. These
parameters are the continuous input and output diode currents
(IlK and 10K) and the continuous output current (10). 11K
and 10K refer to the continuous current that is flowing
through the input and output electrostatic discharge (ESO)
protection circuits (Figure I shows functionally equivalent
schematics of the ESO structures for HC and ACL devices).

To understand how 11K, 10K, and 10 can affect a
system design, consider an example of a partial system
power-down. Figure 2 illustrates a partial power-down
situation where a device powered with Vee = 5 V is driving
a device without power applied. The input voltage to the nonpowered device exceeds Vee by more than the threshold
voltage (0.6 to 0.8 volts), causing the ESO protection
structure to conduct whenever the output of the driver is in
a high state. Therefore, the driving device will power-up the
receiving device and any other device sharing the same Vee
line. If no current limiting is provided, then the maximum
10 of the driving device and the maximum 11K of the
receiving device could be exceeded.

Several methods are available to protect the driving and
receiving devices during partial system power-down. If the
driving device has three-state outputs, then placing the
outputs in a high-impedance state will provide the best
solution. However, if this is not a viable option, then some
method of current limiting must be provided. Figure 3 shows
several methods that can be used, with current-limiting series
resistors being the simplest. The value of the resistor is
chosen to limit the current into the receiving device to less
than 20 rnA. The major drawback to using a current-limiting
resistor is power dissipation. Another drawback is the effect
that the resistor has on the input transition· time at the
receiving device during normal system operation. If the total
capacitance of the interconnects and receiving devices is high
(i.e., a high-capacitance bus), then a current-limiting resistor
will increase the input transition time. A system designer will
have to ensure that the addition of the resistor will not
increase the input transition time above the maximum input
transition time of the receiving device.

A second method of current limiting shown in Figure 3
involves the use of a pull-up resistor and a diode. The
advantage of this method is that it allows for the use of a
large resistor, thereby holding power dissipation to a
minimum. The disadvantage of this method is that it requires
the use of additional components and results in a higher value
of VIL at the receiving device .
A second example of how a partial power-down can
cause unwanted operation is the case of two drivers connected
to the same bus with one device powered down, as shown
in Figure 4. In this case, the first bus driver will attempt
to power-up the second bus driver and any other devices
sharing the same Vee line through the output ESD structure
of the unpowered device.

Vee - 5V

Vee - 5 V

Vee - 0 V

Figure 4. Partial Power-Down with Bus Drivers
Several methods are available to solve this type of
problem. One method is simply to use a current limiting
resistor as outlined above. Another solution is to isolate the
unpowered driver from the Vee line by means of a diode
between the power pin and the Vee supply. If the unpowered
device is a transceiver, then pull-up or pull-down resistors
are required on the output control inputs to disable the
outputs. Not disabling the transceiver outputs would allow
the transceiver to power up the unpowered devices that are
driven by its outputs. Whenever an isolating diode is used,
the Vee at the driver will always be a diode forward drop
below the voltage of the supply, resulting in a degradation
of VOH. Figure 5 illustrates these circuit solutions.
Another example of a system that could require current
limiting protection is one that uses multiple Vee supplies,
or provides each· card with its own on-board voltage
regulator. If the Vee supplies of two connecting devices
differ by more than 0.5 V dc, then a current limiting scheme
should be considered if the driving device is a CMOS device
and is connected to the higher Vee. This is necessary
because VOH of a CMOS device will be the same as Vee
whenever the IoH requirement is very small. Therefore the
input ESD protection diode could conduct if the Vee of the
driver (or VOH) exceeds the Vee of the receiver by more
than 0.5 V dc. It should be pointed out that it is the resulting
current flow that causes the degradation of the diode, not
the voltage. Note: This applies only to supplies that vary
by more than 0.5 V dc. Dynamic switching currents could
cause transient voltage spiking on Vee lines such that a
0.5 V difference between supplies could easily exist. These
transients will not cause a problem as long as their duration
is short (less than 20 ns).

Partial system power-down offers a designer a
convenient method to save on system power consumption.
However, when a partial power-down scheme is used, a
designer must take steps to ensure that no damage occurs
to devices and to avoid excessive power dissipation. He must
also take similar precautions when using multiple Vee
supplies if the supplies of two connecting devices differ by
more than 0.5 V dc.

MECHANICAL DATA

General Description
SMti Tape and Reel offers users of surface-mounted semiconductor
devices a new and efficient method of component handling. Tape and
reel consists of three major elements: a carrier tape. a cover tape. and
a reel.

Carrier Tape

The carrier tape is a conductive material with custom-embossed pockets for a
particular surface-mount package. Components are oriented in the embossed pockets
per EIA 481-A specification "Taping of Surface-Mount Components for Automatic
Placement. "

Cover Tape

With each component in its embossment and protected from mechanical and static
damage, a continuous opaque cover tape is heat sealed over the entire length of the
carrier tape, isolating each component from the outside environment. This heatsealing process guarantees sufficient seal strength to prevent components from falling
from the pockets before use. The cover tape has a peel strength of 40 ± 30 grams in
compliance with EIA 481-A and sufficient strength to ensure consistency during
dereeling operations.

Reel

The entire assemblage is wound on a high-strength polystyrene-based reel. The reel
provides a means of easy storage and handling as well as a method for feeding large
quantities of packages to high-speed placement systems. In addition, SMti Tape and
Reel offers a factory-automation alternative through the use of medium-density
Code 39 bar coding on all reel assemblies. The har code provides source, part
number, date code, and quantity.
