Here is the new INTERFACE catalog from National Semiconductor Corporation. It contains complete
information on all of National's INTERFACE products whether they be Linear, Digital, or MOS. It is
the first such catalog in the industry and we hope it becomes your most important INTERFACE guide.
For your convenience, two different Tables of Contents are provided. One lists the products by type-Line
Driver, Sense Amplifier, etc.-and the other lists the products alphanumencally by part number. Product
selection guides and a complete product applications section are also included.

general description

::t
Further, the LFlll can be used in place of the LMlll
errors due to input currents.

The LFlll, LF211 and LF311 are FET input voltage
comparators that virtually eliminate input current errors.
Designed to operate over a 5.0V to ±15V range the
LFlll can be used in the most critical applications.

elimin~ting

advantages

The extremely low input currents of the LF 111 allows
the use of a simple comparator in applications usually
requiring input current buffering. Leakage testing, long
time delay circuits, charge measurements, and high
source impedance voltage comparisons are easily done.

•

Eliminates input current errors

•

Interchangeable with LM 111

Note 1: This rating applies for ±15V supplies. The pbsitlve input voltage limit is 30V above the negative supply. The negative input voltage limit
is equal to the negative supply voltage or 30V below the positive supply, wh ichever is less.
Note 2: The maximum junction temperature of the LFll1 'is +150°C, the LF211 is +110°C and the LF311 is +B5°C. For operating at elevated
temperatures, devices in the TO-5 package must be derated based on a thermal resistance of +150°C/W. junction to ambient, or +45°C/W, junction
to case. For the flat package, the derating is based on a thermal resistance of +185° elW when mounted on a 1/16-inch-thick epoxy glass board with
ten, 0.03-inch-wide, 2-ounce copper conductors. The thermal resistance of the dual-in-line package is +100°C/W, junction to ambient.
Note 3: These specifications apply for Vs = ±15V and -55°C T A +125° C for the LF 111, unless otherwise stated. With the LF211, however,
all temperature specifications are limited to _25° C T A ~ +85° C and for the LF311 0° C ~ T A +70° C. The offset Voltage, offset current and bias
current specifications apply for any supply voltage from a single 5.0 mV supply up to ± 15V supplies.
Note 4: The offset voltages and offset currents given are the maximum values required to drive the output within a volt of either: supply with a
1.0 mA load. Thus, these parameters define an error band and take into account the worst case effects of voltage gain and input impedance.
Note 5: The response time specified (see definitions) is for a 100 mV mput step with 5.0 mV overdrive.
Note 6: For Input voltages greater than 15V above the negative supply the bias and offset currents will increase-see tYPical performance curves.

LM106/LM206 voltage comparator
general description
The LM 106 and LM206 are high-speed voltage
comparators designed to accurately detect lowlevel analog signals and drive a digital load_ They
are equivalent to an LM710, combined with a two
input NAN D gate and an output buffer. The
circuits can drive RTL, DTL or TTL integrated
circuits directly_ Furthermore, their outputs can
switch voltages up to 24 V at currents as high as
100 mAo Other features include:
• Improved accuracy: 2 mV maximum worst case
offset.
• Fan-out of 10 with DTL or TTL
• Added I,ogic or strobe capability
• tJseful as a relay or lamp driver
• Plug-in replacement for the LM710.

N

oG)

• 40 ns maximum response time'
The devices have short-circuit protection which
limits the inrush current when it is used to drive
incandescent lamps, in addition to preventing
damage from accidental shorts to the positive
supply. The speed is equivalent to that of an
LM710_ However, they are even faster where buffers and additional logic circuitry can be eliminated
by the increased flexibility of the LM106 and
LM206. They can also be operated from any negative supply voltage between -3V and -12V with
little effect on performance.
The LM106 is specified for operation over the
-55°C to +125°C military temperature range. The
LM206 is specified for operation over the -25°C
to +85°C temperature range.

Voltage Comparators
LM306 voltage comparator/buffer
general description
The LM306 is a high-speed voltage comparator
designed to accurately detect low-level analog signals and drive a digital load. It is equivalent to an
LM710e, combined with a two input NAND gate
and an output buffer. The circuit can drive RTL,
DTL or TTL integrated circuits directly. Furthermore, the output can switch voltages up to 24V at
currents as high as 100 mA_ Other features
include:
• Improved accuracy: 5 mV (max) offset
• Fan-out of 10 with DTL or TTL
• Added logic or strobe capability
• Useful as a relay or lamp driver

• Plug-in replacement for the LM710e.
• 40 ns maximum response time
The device has short-circuit protection which
limits the inrush current when it is used to drive
incandescent lamps, in addition to preventing
damage from accidental shorts. The speed is
equivalent to that of an LM710e. However, it is
even faster where buffers and additional logic
circuitry can be eliminated by the increased flexibility of the LM306. It can also be operated from
any negative supply voltage between -3V and
-12V with little effect on performance. The LM306
is identical to the LM 106,except that it is specified
over a oOe to 70°C temperature range.

Voltage Comparators

LM1111LM211 voltage comparator
general description
• Differential input voltage range: ±30V

The LM 111 and LM211 are voltage comparators
that have input currents nearly a thousand times
lower than devices like the LM106 or LM710.
They are also designed to operate over a wider
range of supply voltages: from standard ±15V op
amp supplies down to the single 5V supply used
for IC ·Iogic. Their output is compatible with RTL,
DTL and TTL as well as MaS circuits. Further,
they can drive lamps or relays, switching voltages
up to 50V at currents as high as 50 mAo Out·
standing characteristics include:

• Power consumption: 135 mW at ±15V
Both the inputs and the outputs of the LM 111 or
the LM211 can be isolated from system ground,
and the output can drive loads referred to ground,
the positive supply or the negative supply. Offset
balancing and strobe capability are provided and
outputs can be wire OR' ed. Although slower than
the LM106 and LM710 (200 ns response time vs
40 ns) the devices are also much less -prone to
spurious oscillations. The LM 111 has the same pin
configuration as the LM106 and LM710.

• Operates from single 5V supply

The LM211 IS identical to the LM Ill, except that
its performance is specified over a _25°C to 85°C
temperature range instead of _55°C to 125°C.

• Input current: 150 nA max. over temperature
• Offset current: 20 nA max. over temperature

Note 1: ThIs ratIng applies for ±15V supplies. The positive mput voltage limit IS 30V above the
negatIve supply, The negative mput voltage lImit is equal to the negatIve supply voltage or 30V below
the posItive supply, whichever IS less.

Note 2: The maxImum Junction temperature of the LM111 IS 150°C, while that of the LM?11 IS
11 DoC. For operating at elevated temperatures, devIces in the TO-5 package must be derated based on
a thermal resistance of 150o C/W, junctIon to ambient, or 4SoC/W, junction to case. For the flat
package, the der13ltlOg IS based on a thermal resIstance of 185 0 C/W'when mounted on a 1/16-lnch·thlck
epoxy glass board wIth ten, O.03-lOch-wide, 2-ounce copper conductors. The thermal resistance of the
dual-in-llOe package IS 100o C/W, junction to ambIent.

Note 3: These specifications apply for Vs = ±15V and -55°C ::;TA::; 125°C, unless otherwISe stated.

With the LM211, however, all temperature specifIcations are limIted to _25°C ~TA ::;850 C. The offset voltage, offset current and biBS current specifications apply for any supply voltage from a single 5V

supply up to ±15V supplies.
Note 4: The offset voltages and offset currents given are the maximum values reqUired to drive the
output within a volt of either supply wIth a 1 mA load. Thus, these parameters define an error band
and take Into account the worst case effects of voltage gain and Input Impedance.
Note 5: The response time specifIed (see definitions) IS for a 100 mV Input step with 5 mV overdrive.

LM119/LM219 high speed dual comparator
general description
The LM119/LM219 are precision high speed dual
comparators fabricated on a single monolithic
chip. They are designed to operate over a wide
range of supply voltages down to a single 5V logic
supply and ground. Further, they have higher
gain and lower input currents than devices like
the LM710. The uncommitted collector of the
output stage makes the LM119 compatible with
RTL, DTL and TTL as well as capable of driving
lamps and relays at currents up to 25 mAo Out·
standing features include:

features
• Two independent comparators
• Operates from a single 5V supply
• Typically 80 ns response time at ±15V
•

Minimum fan-out of 2 each side

•

Maximum input current of 1 IlA over temperature
• I nputs and outputs can be isolated from system
ground
• High common mode slew rate

Although designed primarily for applications requiring operation from digital logic supplies, the
LM119 is fully specified for power supplies up to
±15V. It features faster response than the LM111
at the expense of higher power dissipation. However, the high speed, wide operating voltage range
and low package count make the LM 119 much
more versatile than older devices like the LM711.
The LM219 is identical to the LM119, except that
its performance is specified over a -25°C to 85°C
temperature range instead of _55.°C to 125°C.

Note 1: For supply voltages less than ±15V the absolute maximum Input voltage is equal to the supply voltage.
Note 2: The maximum JunctIOn temperature of the LM119 IS 150°C, whIle that of the lM219 IS 110°C. For operating at
elevated temperatures, devices In the TO-5 package must be derated based on a thermal resistance of 150°C/W, junction to
ambient, or 4SoC/W, junction to case. For the flat package, the derating IS based on a thermal resIstance of 18SoC/W when
mounted on a 1/16-lnch-thlck epoxy glass board with ten, O.03-lnch-wide, 2-ounce copper conductors. The thermal resistance
of the dual-m-Ilne package IS 100° C/W, Junction to ambient.
Note 3: These specifications apply for Vs = ±15V and -55°C'::; TA .::; 12SoC, unless otherwise stated. With the LM219,
however, all temperature specIficatIOns are limited to - 2SoC ~ T A ~ 8SoC. The offset voltage, offset current and bIas current
specifications apply for any supply voltage from a smgle 5V supply up to ±15V supplIes.
Note 4: The offset voltages and offset currents given are the maximum values required to drive the output withm a volt of either supply WIth a 1 rnA load. Thus, these parameters define an error band and take Into account the worst case effects of
voltage gain and input Impedance.
Note 5: The response time specified (see definitions) IS for a 100 mV Input step with 5 mV overdrive.

The LM139 series consists of four independent
voltage comparators which were designed specifically to operate from a single power supply over a
wide range of voltages. Operation from split power
supplies is also possible and the low power supply
current drain is Independent of the magnitude of
the power supply voltage. These comparators also
have a unique characterIStic In that the Input
common·mode voltage range includes ground,
even though operated from a single power supply
voltage.

Note 1: For operating at high temperatures, the LM339 must be derated based on +125°C maximum junction temperature and a thermal
resIStance of +175°C/W which applies for the deVice soldered in a printed CirCUit board, operating In a still air ambient. The LM239 and
LM139 must be derated based on a +150°C maximum Junction temperature. The low bias dissipation and the ON-OFF characteristic of the
outputs keeps the chip diSSipatIOn very small (Pd < 100 mW), prOVided the output tranSistors are allowed to saturate.
Note 2: Short CirCUits from the output to V+ ~an cause excessive heating and eventual destruction, The maximum output current IS
approximately 20 mA Independent of the magnitude of V+.
'
Note 3: .Thls ,Input current will only eXist when the voltage at any of the Input leads IS driven negatIve. It IS due to the collector-base
Jun~tlon of the Input PNP transistors becoming forward bIased and thereby acting as Input diode clamps. In addition to thiS diode action,
~here IS also Ia.!eral NPN paraSItiC transistor action on the IC chip. ThiS tranSistor action can cause the output voltages of the comparators
to go to the V voltage 'level (or to ground for a large overdrive) for the time duration that an input IS driven negatIVe. ThiS IS not destructive
and normal output state~ Will re·establish when the Input voltage. which was negative, agam returns to a value greater than -0.3 VOC.
Note 4: These specifIcations apply for. V+ = +5.0 VOC and -5SoC :S TA < +12SoC, unless otherWise stated With the LM239, all
temperature speclflca'tlons ar~ limited to -25° C :S T A :S +85°C and the LM339 temperature specifications are limited to 0° C :S T A ~ +70° C
'Note 5: The direction of the mput current IS out of the IC due to the PNP Input stage. ThiS current IS essentially constant, Independent of
the state of the output so no loading change eXists on the reference or Input lmes.
Note 6: The input common-mode voltage Of either mput Signal voltage should not be allowed to go negative by more than a 3V The upper
end of the common-mode voltage range IS V -1.5V, but either or both Inputs can go to +30 VOC without damage.
Note 7: The response time specified IS for a 100 mV mput step With 5.0 mV overdrive For larger overdrive Signals 300 ns can be obtatned,
see typical performance characteristics section.
Note 8: The pOSitive excursions of the lnput can exceed the power supply voltage level, and If the other mput voltage remains Within the
common-mode voltage range. the comparator Will prOVide a proper output state The low mput voltage state must not be less than -0.3 VOC
(or 0.3 VOC below the magnitude of the negative Dower supply voltage, If used).
Note 9: At output SWitch pOint, Va so: 1.4 VOC, RS =051 With V+ from 5 VOC to 30VOC, and over the full Input common mode range (0 VOC to V+

application hints
The LM139 IS a high gain, wide bandwidth
device; WhiCh, like most comparators, can easily
oscillate if the output lead IS inadvertently allowed
to capacitively couple to the inputs via stray
capacitance. This shows up only during the output
voltage transition intervals as the comparator changes states. Power supply bypassing is not required to solve this problem. Standard PC board
layout is helpful as it reduces stray input·output
coupling. Reducing the input resistors to <10 kn
reduces the feedback signal levels and finally,
adding even a small amount (1 to 10 mV) of positive feedback (hysteresis) causes such a rapid transition that oscillations due to stray feedback are
not possible. Simply socketing the IIC and attaching resistors to the pins will cause input-output
oscillations during the small transition intervals
unless hysteresis IS used. If the input signal is a
pulse waveform, with relatively fast rise and fall
times, hysteresis is not required.
All pins of any unused comparators should be
grounded.
The bias network of the LM139 establishes a
drain current which is independent of the magnitude of the power supply voltage over the range of
from 2Voc to 30 Voc.
It is usually unnecessary to use a bypass capacitor
across the power supply line.

The differential Input voltage may be larger than
V+ without damaging the device. Protection should
be provided to prevent the Input voltages from
gOing negative more than -0.3 V DC (at 2SoC). An
input clamp diode and input resistor can be used
as shown in the applications section.
The output of the LM139 IS the uncommitted
collector of a grounded-emitter NPN output transistor. Many collectors can be tied ti>QethBr to provide an output OR'ing function. An output "pullup" resistor Can be connected to any available
power supply voltage within the permitted supply
voltage range and there is no restriction on this
voltage due to the magnitude of the voltage which
is applied to the V+ terminal of the lM139 package. The output can also be used as a simple SPST
switch to ground (when a "pull-up" resistor is not
used). The amount of current which the output
device can sink is limited by the drive available
(which is independent of V+) and the !3 of this
device. When the maximum current limit is
reached (approximately 16 mAl, the output tran·
sistor will come out of saturation and the output
voltage will rise very rapidly. The output satura·
tion voltage is limited by the approximately 60n
rsat of the output transistor. The low offset voltage
of the output transistor (1 m V) allows the output
to clamp essentially to ground level for small load
currents.

application hints
The LM139A is a high gain, wide bandwidth
device; which, like most comparators, can easily
oscillate if the output lead is inadvertently allowed
to capacitively couple to the inputs via stray
capacitance. This shows up only during the output
voltage transition intervals as the comparator
changes states. Power supply bypassing is not
required to solve this problem. Standard PC board
layout is helpful as it reduces stray input·output
coupling. Reducing the input resistors to < 10 kn
reduces the feedback signal levels and finally,
adding even a small amount (1 to 10 mV) of
positive feedback (hysteresis) causes such a rapid
transition that oscillations due to stray feedback
are not possible. Simply socketing the IC and
attaching resistors to the pins will cause input·
output oscillations during the small transition
intervals unless hysteresis is used. If the input
signal is a pulse waveform, with relatively fast
rise and fall times, hysteresis is not required.
All pins of any unused comparators should be
grounded.
The bias network of the LM139A establishes a
drain current which is independent of the magni·
tude of the power supply voltage over the range
of from 2 Vec to 30 Voc.
It is usually unnecessary to use a bypass capacitor
across the power supply line.
1·36

The differential input voltage may be larger than
V+ without damaging the device (see Note 8).
Protection should be provided to prevent the input
voltages from going negative more than -0.3 Vec
(at 25°C). An input clamp diode can be used as
shown in the applications section.

The output of the LM139A is the uncommitted
collector of a grounded·emitter NPN output tran·
sistor. Many collectors can be tied together to
provide an output OR'ing function. An output
pull·up resistor can be connected to any available
power supply voltage within the permitted supply
voltage range and there is no restriction on this
voltage due to the magnitude of the voltage which
is applied to the V+ terminal of the LM139A
package. The output can also be .used as a simple
SPST switch to ground (when a pull·up resistor is
not used). The amount of current which the
output device can sink is limited by the drive
available (which is independent of V+) and the Il
of this device. When the maximum current limit
is reached (approximately 16 mA). the output
transistor will come out of saturation and the
output voltage will rise very rapidly. The output
saturation voltage is limited by the approximately
60n rsa, of the output transistor. The low offset
voltage of the output transistor (1 mV) allows
the output to clamp essentially to ground level
for small load currents.

LM710 voltage comparator
general description
saturating comparator applications. In fact, the low
stray and wiring capacitances that can be realized
with monolithic construction make the device difficult to duplicate with discrete components operating at equivalent power levels.
The LM710 is useful as a pulse height discriminator, a voltage comparator in high-speed AID converters or a go, no-go detector in automatic test
equipment. It also has applications in digital systems as an adjustable-threshold line receiver or an
interface between logic types. In addition, the low
cost of the unit suggests it for applications replacing relatively simple discrete component circuitry.

The LM710 is a high-speed voltage comparator
intended for use as an accurate, low-level digital
level sensor or as a replacement for operational
amplifiers in comparator applications where speed
is of prime importance. The circuit has a differential input and a single-ended output, with saturated
output levels compatible with practically all types
of integrated logic.
The device is built on a single silicon chip which
insures low offset and thermal drift. The use of
a minimum number of stages along with minoritycarrier lifetime control (gold doping) makes the
circuit much faster than operational amplifiers in

LM710C voltage comparator
general description
The LM710e is a high-speed voltage comparator
intended for use as an accurate, low-level digital
level sensor or as a replacement for operational
amplifiers in comparator applications where speed
is of prime importance. The circuit has a differen·
tial input and a single·ended output, with saturated
output leVels compatible with practically all types
of integrated logic.

with monolithic construction make the device difficult to duplicate with discrete components oper·
ating at equivalent power levels.
The LM710C is useful as a pulse height discriminator,a voltage comparator in high-speed AID converters or a go, no-go detector in automatic test
equipment. It also has applications in digital systems as an adjustable-threshold line receiver or an
interface between logic types. In addition, the low
cost of the unit suggests it for applications replacing
relatively simple discrete component circuitry.
The LM710e is the commercial/industrial version
of the LM710. It is identical to the LM710 except
that operation is specified over a oOe to +70o e
temperature range.

The device is built on a single silicon chip which
insures low offset and thermal drift. The use of a
minimum number of stages along with minoritycarrier lifetime control (gold doping) makes the
circuit much faster than operational amplifiers in
saturating comparator applications. In fact, the low
stray and wiring capacitances that can be realized

Voltage Comparators

LM711 dual comparator
general description
The LM 711 contains two voltage comparators
with separate differential inputs, a common out·
put and provision for strobing each side indepen·
dently. Similar to the LM710, the device features
low offset and thermal drift, a large Input voltage
range, low power consumption, fast recovery from
large overloads and compatibility with most Inte·
grated logic circuits.
With the addition of an external resistor network,
the LM 711 can be used as a sense amplifier for
core memories. The input thresholding, combined
with the high gain of the comparator, eliminates
many of the inaccuracies encountered with jcon·

ventional sense amplifier designs. Further, it has
the speed and accuracy needed for reliably detect·
ing the outputs of cores as small as 20 mils.

The LM711 is also useful In other applications
where a dual comparator with OR' ed outputs is
required, such as a double·ended limit detector. By
using common circuitry for both halves, the device
can provide high speed with lower power dissipa·
tion than two single comparators. The LM 711 is
available in either an 10·lead low profile TO·5
header or a 1/4" by 1/4" metal flat package.

theory of operation

C

::t
o

When both inputs of the DH0034 are raised to
logic "1", the input AND gate is turned "on"
allowing 01's emitter to become forward biased.
01 provides a level shift and constant output current. The collector current is essentially the same
Vee - VeE
as the emitter wh ich is given by
R1
Approximately 7.0 mA flows out of 01's collector.

o
w

About 2 mA of 01's collector current is drawn off
by pull down resistor, R2. The balance, 5 mA, is
available as base drive to 02 and to charge its
associated Miller capacitance. The output is pulled
to within a VSAT of V-. When either (or both}
input to the DH0034 is lowered to logic "0," the
AND gate output drops to 0.2V turning 01 off.
Deprived of base drive 02 rapidly turns off causing
the output to rise to the V3 supply voltage. Since
02's emitter operates between 0.6V and 0.2V, the
speed of the DHOO34 is greatly enhanced.

~

n

applications information
1. Paralleling the Outputs
The outputs of the DH0034 may be paralleled to
increase output drive capability or to accdmplish
the "wire OR". In order to prevent current hogging by one output transistor or the other, resistors of 2 ohms/100 mA value should be inserted
between the emitters of the output transistors and
the minus supply.
2. Recommended Output Voltage Swing
The graph shows boundary conditions which
goVern proper operation lof the DH0034. The
range of operation for the negative, supply is
shown on the X axis and must be between -3V
and -25V. The allowable range for the positive
supply is governed by the value chosen for V-. V+
may be selected by drawing a vertical line through
the selected value for V- and terminated by the

boundaries of the operating region. For example, a
value of V- equal to -6V would dictate values of

DM7800/DM8800 dual voltage translator

Q

general description

features

The DM7800/DM8800 are dual voltage translators
designed for interfacing between conventional TTL
or DTL voltage levels and those levels associated
with high impedance junction or MOS FET-type
devices_ The design allows the user a wide latitude
in his selection of power supply voltages, thus providing custom control of the output swing. The
translator is especially useful in analog switching;
and since low power dissipation occurs in the "off"
state, minimum system power is required.

theory of operation

:E

The two input diodes perform the AND function
on TTL or DTL input voltage levels. When at least
one input voltage is a 10gicar"0", current from Vee
(nominally 5.0V) passes through R 1 and out the
input(s) which is at the low voltage. Other than
small leakage currents, this current drawn from Vee
through the 20 kn resistor is the on Iy source of
power dissipation in the logical "1" output state.

Q
.......

o
o

....CO

:E
Q

When both inputs are at logical" 1" levels, current
passes through R 1 and diverts to transistor 0 1 , turn·
ing it on and thus pulling current through R2 . Current is then supplied to the PNP transistor, O 2 , The
voltage losses caused by current through 0 1, D3 ,
and O2 necessitate that node P reach a voltage sufficient to overcome these losses before current begins to flow. To achieve this voltage at node P, the
inputs must be raised to a voltage level which is one
diode potential lower than node P. Since these levels
are exactly the same as those experienced with conventional TTL and DTL, the interfacing with these
types of circuits is achieved.
Transistor O 2 provides "constant current switching" to the output due to the common base connection of O 2 , When at least one input is at the
logical "0" level, no current is delivered to O 2 ; so
that its collector supplies essentially zero current
to the output stage. But when both inputs are raised
to a logical "1" level current is supplied to O2 ,

Since this current is relatively constant, the collector of O 2 acts as a constant current source for the
output stage. Logic inversion is performed since
logIcal "1" input voltages cause current to be supplied to O 2 and to 0 3 , And when 0 3 turns on the
output voltage drops to the logical "0" level.
The reason for the PNP current source, O2 , is so
that the output stage can be driven from a high
impedance. This allows voltage V2 to be adjusted
in accordance with the application. Negative voltages to -25V can be applied to V 2' Since the output will neither source nor sink large amounts of
current, the output voltage range is almost exclusively dependent upon the values selected for V2
and V3 .
Maximum leakage current through the output transistor 0 3 is specified at 10 J1A under worst-case
voltage between V2 and V3. This will result in a
logical "1" output voltage which is 0.2V below V3.
Likewise the clamping action of diodes D4 , Ds, and
D6, prevents the logical "0" output voltage from
falling lower than 2V above V2, thus establishing
the output voltage swing at typically 2 volts less
than the voltage separation between V 2 and V3'

selecting power supply voltage
The graph shows the boundary conditions which
must be used for proper operation of the unit. The
range of operation for power supply V 2 is shown
on the X axis_ It must be between -25V and -8V.
The allowable range for power supply V3 is governed by supply V2. With a value chosen for V2, V3
may be selected as any value along a vertical line
passing through .the V2 value and terminated by
the boundaries of the operating region. A voltage
difference between power supplies of at least 5V
should be maintained for adequate signal swing.

MH0007/MH0007C dc coupled MOS clock driver

general description

features

The MH0007 is a voltage translator and power
booster designed for interfacing between conven·
tional TTL or DTL voltage levels and those levels
associated with inputs or clocks of MOS F ET type
devices. The design allows the user a wide latitude
in selection of supply voltages, and is especially
useful in normally "off" applications, since power
dissipation is typically only 5 milliwatts in the
"off" state.

• 30 volts (max) output swing
• Standard 5V power supply
• Peak currents in excess of ±300 mA available
• Compatible with all MOS devices
• High speed: 5 I\IIHz with nominal load
• External trimming possible for increased per·
formance

Note 2: The rise time given is the minimum that can be used without exceeding the peak transient
output current for the full rated output load.

circuit operation
Input current forced into the base of 01 through
the coupling capacitor G'N causes 01 to be driven
into saturation, swinging the output to
V- + VeE (SAT) + VOIODEWhen the input current has decayed, or has been
switched, such that 01 turns off, 02 receives base

drive through R2, turning 02 on_ This supplies
current to the load and the output swings positive
to V+ - V EiE .
It may ·'tie noted that 01 always switches off
before 02, begins to supply current; hence, high
internal transient currents from V+ to V- cannot
occur.

Maximum output pulse width is a function of the
Input driver characteristics and the coupling
capacitance and resistance. After being turned on,
the Input current must fall from ItS initial value
liN peak to below the input threshold current

From the graph of power dissipation versus temperature, Figure 7, It can be seen that an
MHOOl3C at 70°C can diSSipate IW Without a heat
Sink. therefore, each half can diSSipate 500 mW.

From Figure 1 (equation I), it can be seen that
at 16V and 30 ns, the maximum load that can be
driven IS limited to 1140 pF.

Figure 4 (equation 3) gives an average power of
102 mW at 16V 40% duty cycle.

For one half of the MHOOl3C
500 mW = 102 mW + 8 mW

390 mW = transient output power
USing Figure 2 (equation 2) at 16V, 1 MHz and

load derived from the transient current limitatIOn
(Figure I, equatlo'n 1), and so a maximum load

The MH0025/MH0025C IS monolithic, low cost,
two phase MOS clock driver that IS designed to be
driven by TTUDTL line drivers or buffers such as
the DM932, DM8830, or DM7440. Two Input
coupll ng capacitors are used to perform the level
shift from TTUDTL to MOS logic levels. Optimum
performance In turn-off delay and fall time are
obtained when the output pulse IS logically controlled by the Input. However, output pulse widths
may be set by selection of the Input capacitors
eliminating the need for tight Input pulse control.

.......
CO

The MH0026 is capable of dellvenng 30 watts
peak power (1.5 amps ~t 20Y needed to rapidly
charge large capacitative loads) while its package is
limited to the watt range. This section describes
the operation of the circuit and how to obtain
optimum system performance. I f additional design
information is required, please contact your local
National field application engineer.

a simplified diagram, D1 (Figure 3) provides 0.7Y
dead zone so that 0 3 IS turned ON for a rising
Input pulse and O 2 OFF prior to 0 1 turning ON a
few nanoseconds later. D2 prevents zenenng of the
emitter·base junction of O 2 and provides an initial
discharge path for the load via 0 3 , During a falling
input, the stored charge In 0 3 is used beneficially'
to keep 0 3 ON thus preventing O 2 from conduct·
ing until 0 1 IS OFF. 0 1 stored charge is quickly
discharged by means of common·base transistor

04 .
2.0 Theory of Operation
Conventional MOS clock drivers like the MH0013
and similar devices have relied on the circuit
configuration in Figure 1. The AC coupling of an
input pulse allows the device to work over a wide
range of supplies while the output pulse width
may be controlled by the time constant - R 1 X C1.

The complete circuit of the MH0026 (see sche·
matic on page 1) basically makes Darllngtons out
of each of the transistors in Figure 3.

D2 provides 0.7Y of dead·zone thus preventing 0 1
and O 2 from conducting at the same time. In
order to drive large capacitive loads, 0 1 and O 2
are large geometry devices but Cob now limits
useful output rise time. A high voltage TTL output
stage (Figure 2) could be used; however, during
switching until the stored charge is removed from
0 1, both output devices conduct at the same time.
This is familiar in TTL with supply line glitches in
the order of 60 to 100 mAo A clock driver built
this way would introduce 1.5 amp spikes into the
supply lines.

FIGURE 2.

When the output of the TTL input element (not
shown) goes to the logic "1" state, current is
supplied through C 'N to the base of O[ and O 2
turning them ON, and 0 3 and 0 4 OF F when the
input voltages reaches 0.7Y. Initial discharge of
the load as well as E·B protection for 0 3 and
are provided by D 1 and D 2 . When the input
voltage reaches about 1.5Y, 0 6 and 0 7 begin to
conduct and the load is rapidly discharged by 0 7 ,
As the input goes low, the input side of C, N goes
negative with respect to Y- causing 0 8 and 0 9 to
conduct momentarily to assure rapid turn·off of
O 2 and 0 7 respectively. When 0 1 and O 2 turn
OF F, Darl ington connected 0 3 and
rapidly
charge the load toward y+ volts. R6 assures that
the output will reach to within one VB E of the
y+ supply.

a.

The real secret of the device's performance is
proper selection of transistor geometries and resis·
tor values so that 0 4 and 0 7 do not conduct at
the same time while minimizing delay from input
to output.
3.0 Power Dissipation Considerations

Alternate MOS Clock Drive

Unique circuit design and advanced semiconductor
processing overcome these clasic problems allow·
ing the high volume manufacture of a device, the
MH0026, that delivers 1.5A peak output currents
with 20ns rise and fall times into 1000pF loads. In

3·36

FIGURE 3. Simplified MH0026

There are four considerations in determining
power dissipations.
1. Average DC power
2. Average AC power
3. Package and heat sink selection
4. Remember-2 drivers per package

s:

:I:

application information (cont.)
The total average power dissipated by the MH0026
is the sum of the DC power and AC transient
power. The total must be less than given package
power ratings.

o

N

Thus for RAM address line applications, package
type and heat sink technique Will limit drive
capability rather than AC power.

3.2 AC Transient Power (per driver)

:I:

en

s:

o
o

AC Transient power is given by:
Since the device dissipates only 2mW with output
voltage high (MOS logic "0"). the dominating
factor in average DC power is duty cycle or the
percent of time in output voltage low state (MOS
logiC "1 "). Percent of total power contributed by
Poc is usually neglible in shift register applications
where duty cycle is less than 25%. Po c dominates
in RAM address line driver applications where
duty cycle can exceed 50%.

Poc

Po 'c

b) Duty cycle = 5%
Poc

c) See graph on page 3
The above illustrates that for shift register applica·
tions, the minimum clock width allowable for the
given type of shift register should be used in order
to drive the largest number of registers per clock

driver.
Example2: W+=+17V, 'V=GND):

DC Power is given by:

= 580mW

PAC

= 290mW per MHz per 1000pF

Thus at 5MHz, a 1000pF load will cause any driver
to dissipate one and one half watts. For long shift
registers, a driver with the highest package power
rating will drive the largest number of bits for the
lowest cost per bit.
3.3 Package Selection
Power ratings are based on a maximum junction
rating of 175°C. The following guidelines are
suggested for package selection. Graphs on page 3
illustrate derating for various operating tempera·
tures.
3.31 TO-5 ("H") Package: Rated at 600mW still
air (derate at 4.0mW/oC above 25°C) and 900mW
with clip on heat sink (derate at 6.0mW/oC above
25°C). This popular hermetic package is recom·
mended for small systems. Low cost (about 10¢)
clip·on·heat sink increases driving capability by
50%.
3.32 8,PIn ("N") Molded MInI·DIP: Rated at
600mW still air (derate at 4.0mWtC above 25°C)
and 1.0 watt soldered to PC board (derate at
6.6mWtC). Constructed with a special copper
lead frame, this package is recommended for
medium size commercial systems particularly
where automatic insertion is used. (Please note for
prototype work, that this package is only rated at
600mW when mounted in a socket and not one
watt until it is soldered down.)
3.33 TO-8 ("G") Package: Rated at 1.5 watts
still air (derate 'at 10mWtC above 25°C) and 2.3
watts with clip on heat Sink (Wakefield type
215-1.9 or equivalent-derate at 15mWtC).
Selected for Its power handling capability and
moderate cost, this hermetic package will drive
very large systems at the lowest cost per bit.

3.4 Summary-Package Power Considerations

Dc

The maximum capacitative load that the MH0026
can drive is thus determined by package type, heat
sink technique, ambient temperature, AC power
(which is proportional to frequency and capacitive
load) and DC power (which is principally deter·
mined by duty cycle). Combining equations previously given, the following formula is valid for ,
any clock driver with negligible input power and '
negligible power in output high state:

4.0 Pulse Width Control

Two external input coupl ing capacitors are required to perform the level translation between
TTLlDTL and MOS logic levels. Selection of the
capacitor size is determined by the desired output
pulse width. Minimum delay and optimum performance is attained when the voltage at the input
of the MH0026 discharges to just above the
devices threshold (about 1.5Vl. If the input is
allowed to discharge below the threshold, to F F
and tf will be degraded. The graph on page 3
shows optimum values for C'N vs desired output
pulse width. The value for C'N may be roughly
predicted by:

5.0 Rise & Fall Time Considerations(Note 3)
The MH0026's peak output current is limited to
1.5A. The peak current limitation restricts the
maximum load capacitance which the device is
capable of driving and is given by:
1= C L
The rise time,
predicted by:

t"

dv

at.';; 1.5A
for various loads may be

t, = (LW) (250 X 10- 12 + C L )

== V+ - VC L = The load capacitance
For V+ - V- = 20V, C L = 1OOOpF, t, is:

==
=

(20V) (250 X 10- 12
25ns

+ 10- 12 )

For small values of C L , equation above predicts
optimistic values for t,. The graph on page 3
shows typical rISe times for various load capaci·
tances.
The output fall time (see Graph) may be predicted
by:
t f == 2.2R(C s +~)

practice, determination of a value for L is rather
difficult. However,R s is readily determined emper·
ically, and values typically range between 10 and
51 ohms. Rs does reduce rise and fall times as
given by:

6.0 Clock Overshoot
The output waveform of the MH0026 can over·
shoot. The overshoot is due to finite inductance of
the clock lines. It occurs on the negative going
edge when 0 7 saturates, and on the positive edge
when 0 3 turns OFF as the output goes through
V+ - V be' The problem can be eliminated by
placing a small series resistor In the ouput of the
MH0026. The critical valve for Rs= 2yLlCQ where
L is the self·inductance of the clock line. In

(about 1.5V above ground). Figure 1 depicts the

cycle.

POWER CONSIDERATIONS

For practical cases the PAC TTL can be neglected
as being very small compared to PAC MOS,

Internal power dissipation is affected by three
factors:
• dc power
• ac power
• package dissipation capability
The total average power dissipation is the summation of the dc power and ac power. This sum
must be less than the maximum package dissipation capability at the particular operating temperature to insure safe operation, i.e.:
P01SS ~ PAC + POC .:; PMAX

Thus P01SS is the sum of the MaS transient
power (total for both sides of the MH7B03) and
the standby power of the TIL and MaS sections
of the MH7B03.
DECOUPLING

It is recommended that each device be decoupled
with a O.l!lF capacitor from Vss to Voo. If there
is noise on the supply lines, better frequency and
pulse width stability can be obtained by connecting
a O.OOl!l F capacitor from the frequency control
pin to V 00 and another O.OOl!lF capacitor from
the pulse width control pin to Voo.

The MH8808 IS a high speed dual MOS clock
driver intended to drive the two phases of a
memory array of 500 pF per phase at rates up to
4 MHz. The design Includes output current limit·
Ing for controlled rise and fall times, and thermal
shutdown which protects the chip against excessive power dissipation or accidental output shorts.
Two DTL!TTL compatible status outputs monitor
clock outputs and provide a corresponding TTL
logic level for status indication. Both direct and
internally damped outputs are available for each
phase to suit the particular application. It is ideally
suited for driving MM5262 2k RAMs.

The DM7820, specified from ·55°e to 125°e, and
the DM8820, specified from oOe to 70 o e, are
digital line receivers with two completely indepen'
dent units fabricated on a single silicon chip.
Intended for use with digital systems connected
by twisted pair lines, they have a differential input
designed to reject large common mode signals while
responding to small differential signals. The output
is directly compatible with RTL, DTL or TTL
integrated circuits.

• Each channel can be strobed independently
• High input resistance
• Fanout of two with either DTL or TTL
integrated circuits
The response time can be controlled with an ex·
ternal capacitor to eliminate noise spikes, and the
output state is determined for open inputs. Ter·
mination resistors for the twisted pair line are
also included in the circuit. Both the DM7820 and
the DM8820 are specified, worst case, over their
full operating temperature range, for ±10·percent
supply voltage variations and over the entire input
voltage range.

general description

Q

The DM7820A and the DM8820A are improved
performance digital line receivers with two completely Independent units fabncated on a single
silicon chip. Intended for use with digital systems
connected by twisted pair lines, they have a differential Input designed to reject large common mode
signals while responding to small differential SIgnals. The output is directly compatible with RTL,
DTL or TTL integrated circuits. Some Important
design features include:

•

• Outputs can be wire OR'ed
• Series 54174 compatible
The response time can be controlled with an ex·
ternal capacitor to reject Input noise spikes. The
output state is a logic "," for both inputs open.
Termination resistors for the twisted pair lille are
also included in the circuit. Both the DM7820A
and the DM8820A are specified, worst case, over
their full operating temperature range (_55°C
to '25°e and oOe to 70°C respectively). over the
entire input voltage range, for ±'O% supply voltage variations.

• Operation from a single +5V logic supply
Input voltage range of ±'5V

•

• Strobe low forces output to "," state
•

general description
• High impedance output state which allows
many outputs to be connected to a common
bus line.

Through simple logic control, the DM7831/
DM8831, DM7832/DM8832 can be used as either
a quad single-ended line driver or a dual differential
line driver. They are specifically designed for
party line (bus-organized) systems. The DM7832/
DM8832 does not have the Vee clamp diodes
found on the DM7831/DM8831.

mode of operation
To operate as a quad single-ended line driver apply
logical "O"s to the Output Disable pins (to keep
the outputs in the normal low impedance mode)
and apply logical "O'''s to both Differential/
Single·ended Mode Control inputs. All four
channels will then operate independently and no
signal inversion will occur between inputs and
outputs.

The DM7831 & DM7832 are specified for operation over the -55°C to +125°C military temperature range. The DM8831 & DM8832 are specified
for operation over the O°C to +70°C temperature
range.

To operate as a dual differential line driver apply
logical "O"s to the Output Disable pins and apply
at least one logical "1" to the Differential/Singleended Mode Control inputs. The inputs to the A
channels should be connected together and the
inputs to the B channels should be connected toIn this mode the signals applied to the resulting
inputs will pass non·inverted on the A2 and B2 outputs and inverted on the A, and B, outputs.

features
• Series 54174 compatible
• 17 ns propagation delay
low output impedance-high dril,
• Very

• 40 mA sink and source currents
• Gating control to allow either single-ended or
differential operation

"high impedance" state. This is accomplished by
ensuring that a logical "1" is applied to at least
one of the Output Disable pins of each device
which is to be in the "high impedance" state. A
NOR gate was purposely chosen for this function
since it is possible with only two DM5442/
DM7442, 8CD-to-decimal decoders, to decode as
many as 100 DM}831/DM8831's, DM7832/

drive capability and waveform Integrity especially
during the transition from the logical "0" to
logical "1" state. The other outputs-in the high
Impedance state-take only a small amount· of
leakage current from the low Impedance outputs.
Smce the logical "1" output current from tne
selected device is 100 times that of a conventional
Series 54174. device (40 mA vs. 400 MA), the
output is easily able to supply that leakage current
for several hundred other DM7831/DM8831's,

general description
The DM7836/DM8836 are quad 2-lnput receivers
designed for use In bus organized data transmission
systems interconnected by terminated 120Q impedance lines_ The external termination IS intended to be 180Q reSIStor from the bus to the +5V
logic supply together with a 390Q resistor from
the bus to ground_ The design employs a built-in
input hysteresIs providing substantial noise Immunity. Low Input current allows up to 27 drlver/
receiver pairs to utilize a common bus. This receiver has been specifically configured to replace
the SP380 gate pln-for-pln to provide the distinct
advantages of the DM7837 receiver design in eXistIng systems. Performance IS optimized for systems
with bus rISe and fall times ~ lOps.

general description

features

The DM7837/DM8837 are high speed receivers designed for use in bus organized data transmission
systems Interconnected by terminated 120n Impedance lines. The external termination is intended to be 180[2 reSIStor from the bus to the +5V
logic supply together with a 390[2 resistor from
the bus to ground. The receiver design employs a
built-in Input hysteresIs providing substantial nOise
Immunity. Low input current allows up to 27 driver/receiver pairs to utilize a common bus. Disable
Inputs provide time discriminatIOn. Disable Inputs
and receiver outputs are DTL/TTL compatible.
Performance is optimized for systems with bus

Note 2: The maX1mum junction temperature of the LM14SS is 150°C. For operating at elevated temperatures the cavity
Dual-In-Line Package (J) must be derated based on a thermal resistance of 85°C/W, junction to ambient.
Note 3: These specifications apply for V+ = +9.0V ± 1%, V- = -9.0V ± 1%, TA = O°C to +75°C unless otherwISe noted. All
typicals are for V+ = 9.0V, V- = -9.0V, and T A = 25°C.

applications
RS232C specifies that the output slew rate must
not exceed 30V per microsecond. Using the worst
case output short circuit current of 12 mA in the
above equation, calculations result In a required
capacitor of 400 pF connected to each output.

By connecting a capacitor to each driver output
the slew rate can be controlled utilIZing ,the output
current limiting characteristics of the LM1488.
For a set slew rate the appropriate capacitor value
may be calculated uSing the following relationship,
C = Isc (llT/llV)
where C IS the required capacitor, Isc IS the short
CirCU It cu rrent value, and II VIII T IS the slew rate.

LM75123 dual line driver
general description

features

The LM75123 is a monolithic dual line driver
designed specifically to meet the I/O interface
specifications for IBM System 360. It is compatible with standard TIL logic and supply voltage
levels.

• Meet IBM System 360 I/O interface specifications for digital data transmission over 500 to
500n coaxial cable, strip line, or terminated
pair transmission lines
• TIL compatible with single 5.0V supply

The low-impedance emitter-follower outputs of
the LM75123 enable driving terminated low impedance lines. In addition the outputs are uncommited allowing two or more drivers to drive
the same line.

• 3.11V output at IOH = -59.3 mA
• Open emitter-follower output structure for
party-line operation
• Short circuit protection
• AND-OR logic configuration

Output short-circuit protection is incorporated
to tum off the output when, the output voltage
drops below approximately 1.5V.

• Plug-in replacement for the SN75123 and the
8T23

Note 1: "Absolute Maximum Ratings" are those values beyond which the safety of the device cannot be guaranteed. Except
for "Operating Temperature Range" they are not meant to imply that the devices should be operated at these limits. The
table of "Electrical Characteristics" provides conditions for actual device operation.
Note 2: All currents into device pins are shown as positive, currents out of device pins shown as negative, all voltage values are
referenced with respect to network ground terminal, unless otherwise noted. All values shown as max or min on absolute
value basis.
Note 3: Minimax limits apply across the guaranteed operating temperature range of O'C to +75'C for LM75123, unless
otherwise specified. Typicals are for VCC = 5.0V, T A = 25·C. POSItive current IS defined as current into the referenced pin.
Note 4: The output voltage and current limits Bre guaranteed for any appropriate combination of high and low inputs
specified by the truth table for the desired output.
Note 5: For operating at elevated temperatures, the cavity DIP package (J) hes a maximum junction temperature of +lSetC
and must be derated based on a thermal resistance of +85·C/W, junction to ambient. The molded DIP package (N) hes a maximum junction temperature of +150°C and must be derated based on a thermal resistance of +150'C/W, junction to ambient.

there is less likelihood of false turn-on due to an
inadvertent short in the drive line.

The DH0006/DH0006C IS an Integrated high
voltage, high current driver designed to accept
standard DTL or TTL logic levels and drive
a load of up to 400 mA at 28 volts. AND inputs
are provided along with an Expander connection,
should additional gating be required. The addition
of an external capacitor provides control of
the rise and fall times of the output in order to
decrease cold lamp surges or to minimize electro·
magnetic interference if long lines are driven.

features
• Operation from a Single + 1OV to +45V Power
Supply.
• Low Standby Power Dissipation of only 35 mW
for 28V Power Supply.
• 1.5A, 50 ms, Pulse Current Capability.

Since one side of the load is normally grounded,

general description
Applications include driving lamps, relays, cores,
and other devices requiring several hundred milliamp currents at voltages up to 40V. Logic flexibility is provided through a 4-input NAND gate, a
NOR input and an input which bypasses the geting
and connects the base of the output transistor.

The DH0011 high voltage, high current driver
tamily consists of hybrid integrated circuits which
provide a wide range of variations in temperature
range, package, and output current drive capability. A summary of the variations is listed below.

general description
features
The LM3611 series of dual peripheral drivers was
designed for those applications where a higher
breakdown voltage is required than that provided
by the LM75451 series. The pin outs for the
circuits are identical to those of the LM75451 to
LM75454. The LM3611 series parts feature high
voltage outputs (80V breakdown in the "off" state)
as well as high current (300 mA in the "on" state).
Typical applications include power drivers, relay
drivers, lamp drivers, MOS drivers, and memory
drivers.

• 300 mA output current capability per driver
80V

• Hlgh·voltage outputs
• TTL or DTL compatible
• Input clamping diodes
• Choice of logic function

DM5441A/DM7441A
BCD to decimal decoder/nixie* driver
general description
The DM5441AIDM7441A is monolithic blnarycoded-decimal to decimal decoder. The BCD
number to be decoded IS applied to the four
input lines; and the unique output correspond Ing
to the decimal equivalent of the input number
falls to a logical 0 level. Outputs are designed to
drive gas-filled-readout (Nixle*) tubes but are also

able to operate with other low current lamps
and re·lays.
An over-range feature provides that if binary numbers between 10 and 15 are applied to the input
the least significant bit of these numbers (0
through 5) will be decoded on the output.

Display Drivers
DM5446A/DM7446A
DM5447A/DM7447A
DM5448/DM7448
BCD-to-7-segment decoder/drivers
general description
This versatile series of 7-segment display drivers
fulfills a wide variety of requirements for most
active high (common cathode) and active low
(common anode) Light Emitting Diodes (LED)
or lamp displays. Each device fully decodes a
4-bit BCD input into a number from 0 through 9
in the standard 7-segment display format, and
BCD numbers above 9 Into unique patterns that
verify operation. All circuits operate from a
single 5.0V supply.
The DM5446A/DM7446A has active-low, opencollector outputs that will drive segments requiring
up to 40 mA of current. The outputs are capable
of withstanding 30V at a maximum leakage current
of 2501lA. This configuration is particularly well
suited for common anode LED displays or higher
voltage lamp displays. The high sink current
capability also allows this circuit to be used in
the multiplex or nonmultiplex mode of display
drive. In addition, the device may be used to
drive logic circuits since its normalized fanout
is 25.
The DM5447 A/DM7447 A has tne same output
characteristics as the DM5446A/DM7446A except
that the outputs withstand 15V at a maximum

leakage current ot2501lA. Since its output configuration IS the same as the DM5446AIDM7446A
ItS applications will also be the same, the only
restriction is that a lower voltage type display be
used because of the reduced output voltage limit
of 15V.
The DM5448/DM7448 has active-high, passivepull up outputs with a fanout of 4. Typical source
current is 2.0 mA at an output voltage of 0.85V.
The sink capability is 6.4 mA at a maximum
voltage of O.4V. It is normally used to drive logic
circuits, operate high-voltage loads such as electroluminescent displays through buffer transistors or
SCR switches, and in low current common cathode
Non-Multiplex LED applications.

DM54141/DM74141
BCD to decimal decoder/driver
general description
The DM54141/DM74141 is a second-generation
BCD to decimal decoder designed specifically to
drive cold cathode indicator tubes. This decoder
demonstrates an improved capability to minimize
switching tra'nsients in order to maintain a stable
display.
Full decoding is provided for all possible input
states. For binary inputs 10 through 15, all the
outputs are off. Therefore the DM54141/DM74141,
combined with a minimum of external circuitry,
can use these invalid codes in blanking leadingand/or trailing-edge zeros in a display as shown in
the typical application data. The ten high-performance NPN output transistors have a maximum
reverse current of 50MA at 55V.
Low-forward-impedance diodes are also provided
for each input to clamp negative-voltage transitions

logic diagram

in order to minimize transmission-line effects.
Power dissipation is typically 55 mW, which is
about one-half the power requirement of earlier
designs.

DM75493 quad LED segment driver
general description

features

The OM75493 is a quad LED segment driver. It
is designed to interface between MOS IC's and
LED's. An external resistor is required for each
segment to drive the output current which is
approximately equal to O.7V/RL and is relatively
con.tant, independent ot supply variations. Blank·
ing can be achievecj by taking the chip enable
(CE) to a logical "1" level.

general description

o

This series of 7-segment display drivers fulfills a
wide variety of requirements for most active high
(common cathode) Light Emitting Diodes (LEDs).
Each device fully decodes a 4-bit BCD input into
a number from 0 through 9 in the standard 7segment display format, and BCD numbers above
9 into unique patterns that verify operation. All
circuits operate off of a single 5.0V supply.

3:

In addition, with the use of an external current
limit resistor per segment, this circuit can be used
in higher current nonmultiplex LED applications.

00
00

~

The DM7858/DM8858 has active high outputs
with source current adjustable with the use of
external current limit resistors, one per segment.
This feature allows extreme flexibility in source
current value selection for either multiplex or
non-multiplex common cathode LED drive applications. It allows the system designer freedom to tailor
the drive current for his particular applications.

The DM7856/DM8856 has active-high, passive
pull-up outputs which provide a typical source
current of 6.0 mA at an output voltage of 1. 7V.
The applications are the same as for the DM5448/
DM7448 except that more design freedom is
allowed with higher source current levels. This
circuit was designed to drive the MAN-4 or equivalent type display directly without the use of
external current limit resistors.

Note 1: BI/ABO IS wlre~AND logic serving as blanking Input (Btl and/or rlppJe~blanking output (RBO). The blanking Input (BI)
must be open or held at a logical 1 when output functions 0 through 15 are desired, and the npple~blanklng Input (RBI)
must be open or at a logical 1 If blanking of a decimal 0 IS not desired. X = Input may be high or low.
Note 2: When a logical 0 IS applied directly to the blanking Input (forced condition) all segment outputs go to a logical 1
regardless of the state of any other mput condition
Note 3: When the npple~blanking Input (RBI) and Inputs A, B, C, and D are at logical 0, with the lamp test Input at logical 1,
all segment outputs go to a logical 1 and the npple~blanking output (RBO) goes to a logical 0 (response condition).
Note 4: When the blanking Input/npple~blanklng output (BIIRBO) IS open or held at a logical 1, and a logical 0 is applied to
the lamp~test Input, all segment outputs go to a logical O.

DM8859, DM8869 TTL compatible hex LED drivers

en

CD

general description
The DM8859, DM8869 are TTL compatible hex
LED drivers with programmable current source
outputs. The current sources are nominally set
at 20 mA but may be adjusted by external
resistors for any value between 0-50 mA. Each
device contains six latches which may be set by
input data terminals. A strobe common to all six
latches enables the data input terminals. The
DM8859 current source outputs are switched on

by entering a high level into the latches and the
DM8869 current source outputs are switched on
by entering a low level into the latches.
The devices are available in either a molded or
cavity package. In order not to damage the devices
there is a limit placed on the power dissipation
allowable for each package type. This information
is shown in the graph on the back page.

general description
Output currents may be varied over the 0.2 to 1 5

design prOVides a one·to-one correlation between
program Input current and b-segment output

The DM7880/DM8880 is custom designed to decode four lines of BCD and drive a gas-filled
seven-segment display tube.
The design employs a 112-bit read-only memory
which provides BCD Input to full hexadecimal output decoding In the standard DM7880/DM8880
product. For applications desiring other fonts, or
not using standard BCD coding, the ROM contents
can be custom modified to produce any 16 output
displays for the 16 binary Input combinations.

The Blanking Input prOVides unconditional blank·
Ing of any output dISplay, while the Ripple Blanking pinS allow simple leadlng- or tralllng·zero
blanking.

Each output constitutes a sWltchable, adjustable
current

sink

which

prOVides

constant current

to the tube segment, even with high tube anode
supply tolerance or fluctuation. These current
sinks have a voltage compliance from 3V to
at least 80V; tYPically the output current vanes
1% for output voltage changes of 3 to 50V. Each
bit line of the ROM switches a current Sink on
or off as prescribed by the input code. Each
current Sink is ratloed to the b-output current
as required for even illumination of all segments.

general description
The DM8884A is designed to decode four lines of
BCD input and drive seven-segment digits of gasfilled readout displays. Two separate Inputs are
provided for driving the decimal point and comma
cathodes.

curve.

All outputs conSISt of switchable and programable current sinks which provide constant current
to the tube cathodes, even with high tube anode
supply tolerance. Output currents may be varied
over the 0.2 to 1.2 mA range for mUltiplex operation. The output current IS adjusted by connecting
an external program resistor (Rp) from Vee to the

general discription
The DM8885 mterfaces MOS calculator or counterlatch-decoder-drlver CirCUits directly to sevensegment high-voltage gas-filled dlsplays_ The SIX
inputs A, B, D, E, F, G are decoded to drive the
seven segments of the tube.

by connecting a program resistor (Rp) from Vee to
the program Input-

Each output constitutes a sWltchable, adjustable
current source which prOVides constant current to
the tube segment, even With high tube anode supply
tolerance or fluctuation. These current sources have
a voltage compliance from 3V to at least 80V. Each
current source is ratloed to the b-output current
as required for even Illumination of all segments.
Output currents may be varied over the 0.2 to
1.5 mA range for drivmg various tube types or

C

The DM7802/DM8802, DM7806/DM8806 are high
speed MOS to TTL level converters. These circuits
act as an interface level converter between MOS
-and TTL logic devices. It consists of two 1-input
converters with common strobe input to inhibit
"0" entry when strobe is high. It allows parallel
entry when strobe is low and the internal latch
is preset by the common preset input. TR 1STATE@ output logic is implemented in this
circuit to facilitate high speed time sharing of
decoder-drivers, fast random-access (or sequential)
memory arrays, etc .

LM5520/LM7520 series
dual core memory sense amplifiers
general description
The devices in this series of dual core sense
amplifiers convert bipolar millivolt-level memory
sense signals to saturated logic levels. The design
employs a common reference input which allows
the input threshold voltage level of both amplifiers
to be adjusted. Separate strobe inputs provide time
discrimination for each channel. Logic inputs and
outputs are DTUTTL compatible. All devices of
the series have identical preamplifier configurations, while various logic connections are provided
to suit the specific application.
The LM5520/LM7520 has output latch capability
and provides sense, strobe, and memory function
for two sense lines. The LM5522/LM7522 contains a single open collector output which may be
used to expand the number of inputs of the
LM5520/LM7520, or to drive an external Memory
Data Register (MDR). Intended for small memories, the two channels of the LM5524/LM7524 are
independent with two separate outputs. The
LM5534/LM7534 is similar to the LM55241
LM7524 but has uncommitted, wire-aRable outputs. The LM5528/LM7528 has the same logic
configuration of the LM5524/LM7524 and in
addition provides separate low impedance Test
Points at each preamplifier output. A similar
device having uncommitted, wire-aRable outputs
is the LM5538/LM7538.

general description
This series of TTL/DTL compatible MOS analog
switches feature high speed with internal level
shifting and driving. The package contains two
monolithic integrated circu it chips: the MOS ana·
log chip is similar to the MM450 type which
consists of four MOS analog switch transistors;
the second chip is a bipolar I.C. gate and level
shifter. The series is available in both hermetic
dual·in·line package and flatpack.

The graph shows the boundary conditions which
must be used for proper operation of the unit.
The range of operation for power supply V- is
shown on the X axis. It must be between -25V
and -8V. The allowable range for power supply
V+ is governed by supply V-. With a value chosen
for V-, V+ may be selected as any value along a
vertical line passing through the V- value and
terminated by the boundaries of the operating
region. A voltage difference between power supplies of at least ~V should be maintained for
adequate signal swing.

1. INPUT LOGIC COMPATIBILITY
A.

'

::J:
.......

Voltage Considerations

In general, the AH0100 series is compatible with
most DTL, TTL, and RTL logic families. The ON·
input threshold is determined by the V BE of the
input transistor plus the V f of the diode in the
emitter leg, plus I x R" plus VA' At room
temperature and VA = OV, the nominal ON thres·
hold is: O. 7V +0. 7V+0.2V, = 1.6V.Over temperature
and manufacturing tolerances, the threshold may
be as high as 2.5V and as low as 0,8V, The rules
for proper operation are:

terminal will open all switches. The VA (ENABLE)
signal must be capable of rising to within 0.8V of
V'NION) in the OFF state and of sinking I AION )
milliamps in the ON state (at V'N(ON) - VA
2.5V). The V A terminal can be driven from most
TTL and DTLgates.

>

3. DIFFERENTIAL INPUT CONSIDERATIONS
The differential switch driver is essentially a differential amplifier. The input requirements for proper
operation are:
IV,N , - V ,N2 1:::: 0.3V

V ,N - VA ~ 2,5V All switches ON

::J:

«
.......

V ,N - VA S; 0,8V All switches OFF

...o
M

::J:

«
o
N
....
o
::J:
«

.......

2.5 ~ (V ,N , or V ,N2) - v'A ~ 5V
The differential driver may be furnished by a DC
level' as shown below. The level may be derived
from a voltage divider to V+ or the 5V Vee of
the DTL logic. In order to assure proper operation,
the divider should be "stiff" with respect to I,N2'
Bypassing R 1 with a 0.1 IlF disc capacitor will
prevent degradation of tON and tOFF'

B. Input Current Considerations
I'NION), the current drawn by the driver with
V ,N = 2.5V is typically 20 IlA at 25°C and is guar·
anteed less than 120 IlA over temperature. DTL,
such as the DM930 series can supply 180 IlA at
logic "1" voltages in excess of 2,5V. TTL output
levels are comparable at 400 IlA. The DTL and
TTL can drive the AH0100 series directly. However, at low temperature, DC noise margin in the
logic "1" state is eroded with DTl. A pull-up resistor of 10 kQ is recommended when using DTL
over military temperature range.
If more than one driver is to be driven by a DM930
series (6K) gate, an external pull-up resistor should
be added. The value is given by:
11
Rp = N _ 1 for N

>2

where:
Rp = value of the pull-up resistor in kQ
N
C.

= number of drivers.

Input Slew Rate

The slew rate of the logic input must be in excess
of 0.3V Ills in order to assure proper operation of
the analog switch. DTL, TTL, and RTL output
rise times are far in excess of the minimum slew
rate requirements. Discrete logic designs, however,
should include consideration of input rise time.

Alternatively, the differential driver may be driven
from a TTL flip-flop or inverter.

Connection of almA current source between V A
and V- will allow operation over a ±1 OV common
mode range. Differential input voltage must be less
than the 6V breakdown, and input threshold of
2.5V and 300mV differential overdrive still. prevail.

4. ANALOG VOLTAGE CONSIDERATIONS
The rules for operating the AH0100 series at
supply voltages other than those specified essentially breakdown Into OFF and ON considerations.
The OFF considerations are dictated by the maximum negative sWing of the analog signal and the
pinch off of the JFET switch. In the OFF state,
the gate of the FET is at V- + VeE + VSAT or
about 1.0V above the V- potential. The maximum
Vp of the FET switches is 7V. The most negative
analog voltage, V A, sWing which can be accomodated for any given supply voltage IS:
IVAI:SIV-I-Vp - VeE - VSAT or
IV AI<:::;lv-I-8.0 or IV-I2':IV AI+8.0V
For the standard high level switches, VA <1- 181
+8 = -10V. The value for V+ is dictated-by the
maximum positive swing of the analog input voltage. Essentially the collector to base junction of
the turn-on PNP must remain reversed biased for
all positive value of analog input voltage. The base
of the PNP is at V+ - VSAT - VeE or V+ - 1.0V.
The PNP's collector base junction should have at
least 1.0V reverse bias. Hence, the most positive
analog voltage swing which may be accommodated
for a given value of V+ is:

VA

:s v+ - 2.0V or V+ ::: VA + 2.0V

For the standard high level sWitches, V A = 12 2.0V = +10V.
5. SWITCHING TRANSIENTS
Due to charge stored In the gate-to-source and
gate-to-drain capacitances of the FET switch, transients may appear in the output during switching.
This IS particularly true during the OFF to ON
transition. The magnitude and duration of the
transient may be minimized by making source
and load impedance levels as small as practical.

Furthermore, transients may be minimized by
operating the sWitches in the differential mode;
i.e., the charge delivered to the load during the
ON to OFF transition is, to a large extent, cancelled by the OFF to ON transition.

In a typical application, VA might = ±10V, AD
0.1 %, O°C < T A < 8SoC. The criterion of equation
(2b) predicts:
10V
R1(MIN)
Skn
- 20MA

>---=
10

For R, = R2, gain accuracy is determined by the
rOS(ON) match between 0, and O2, Standard
match between 0, and O2 is son resulting in a
gain accuracy of O.S% (for R, = R2 = 10k).
Tighter rOS(ON) match versions are available.
Noise Immunity
The switches with the source diodes grounded
exhibit improved noise immunity for positive
analog signals in the "OFF" state. With V 1N = lSV
and the VA = +10V, the source of 0, is clamped
to about 0.6V by the diode (V GS = 14.4V). The
"ON" impedance of the diode is about 26n
ensuring that AC signals imposed on the +10V
will not gate the FET "ON_"

For R, = Sk, Is:; 10V/Sk or 2 mAo The electrical
characteristics guarantee an IO(ON) < lilA at 8SoC
for the AHS010C_ Per the criterion of equation
(2a):
(1 OV) (10- 3 )
R1(MIN) 2::
10kn

1 x 10-6

Since equation (2a) predicts a higher value, the
10k resistor should be used_

'" o-"M.-<......- - ,

Selection of Gain Setting Resistors
Since the AHS009 series of analog switches are
operated current mode, it is generally advisable to
make the signal current as large as possible. However, current through the FET switch tends to forward bias the gate to channel (source) diode
resulting in leakage across the diode. This leakage,
IO(ON), increases exponentially with increasing Is.
As shown in Figure 2, IO(ON) represents a finite
error in the current reaching the summing junction
of the op amp.
8-16

FIGURE 3.

The "OFF" condition of the FET also effects gain
accuracy. As shown in Figure 3, the leakage across
O2 , IO(OFF) represents a finite error in the, current
arriving at the summing junction of the op amp.

Standard TTL gates pull-up to about 3.5V (no
load). In order to ensure turn-off of the even
numbered switches such as AH5010, a pull-up
resistor, R EXT , of at least 10 kn should be placed
between the 5V Vee and the gate output as shown
in Figure 4.
Likewise, the open-collector, high voltage TTL
outputs should use a pull-up resistor as shown in
Figure 5. In both cases, tloFF) is improved for
lower values of REXT and the expense of power
dissipation in the' low state.

Selection of R2 , of course, depends on the gain
desired and for unity gain R 1 = R2 .
Lastly, the foregoing discussion has ignored resis·
tor tolerances, input bias current and offset
voltage of the op amp - all of which should be
considered in setting the overall gain accuracy of
the circuit.

The LF1650/LF2650/LF3650 is a monolithic combination of bipolar and JFET technology producing the
industry's first one chip quad FET switch_ A unique
circuit technique is employed to maintain a constant
RON over the analog voltage range. The input is designed
to operate from minimum TTL levels. and switch
operation also ensures a break before make action.

*Note: The above graph indicates the analog current at which 1% of the analog current is lost.
When the drain of the analog switch IS positive with respect to the source the drain gate junction tends to forward bias and the output

FET becomes a PNP transistor with base and substrate current losses. Operation In this mode allows much higher analog currents while
maintaining a minimum RON.

I nput Gate Protection

•

Zero Offset Voltage

Each gate input is protected from static charge
build-up by the incorporation of zener diode protective devices connected between the gate input
and device bulk.

These devices are useful in many airborne and
ground support systems requiring multiplexing,
analog transmission, and numerous signal routing
applications. The use of low threshold transistors
(VTH = 2 volts) permits operations with large analog input swings (± 10 volts) at low gate voltages
(~20 volts). Significant features, then, include:'

The MM450, MM451, MM452 and MM455 are
specified for operation over the _55°C to +125°C
military temperature range. The MM550, MM551,
MM552 and MM555 are specified for operation
over the -25°C to + 70°C temperature range.

INTRODUCTION

;:;:
III

c

It is frequently necessary to transmit digital data
in a high-noise environment where ordinary integrated logic circuits cannot be used because they
do not have sufficient noise immunity. One solu·
tion to this problem, of course, is to use highnoise·immunity logic. In many cases, this approach
would require worst case logic swings of 30V,
requiring high power-supply voltages. Further,
considerable power would be needed to transmit
these voltage levels at high speed. This is especially
true if the lines must be terminated to eliminate
reflections, since practical transmission lines have a
low characteristic impedance.

A much better solution is to convert the ground
referred digital data at the transmission end into a
differential signal and transmit this down a balanced, twisted-pair line. At the receiving end, any
induced noise, or voltage due to ground-loop currents, appears equally on both ends of the
twisted-pair line. Hence, a receiver which responds
only to the differential signal from the line will
reject the undesired signals even with moderate
voltage swings from the transmitter.
Figure 1 illustrates this situation more clearly.
When ground is used as a signal return as in Figure la, the voltage seen at the receiving end will be
the output voltage of the transmitter plus any
noise voltage induced in the signal line. Hence, the
noise immunity of the transmitter-receiver combination must be equal to the maximum expected
noise from both sources.
The differential transmission scheme diagrammed
in Figure 1b solves this problem. Any ground noise
or voltage induced on the transmission lines will
appear equally on both inputs of the receiver. The
receiver responds only to the differential signal
coming out of the twisted-pair line and delivers a
single·ended output signal referred to the ground

at the receiving end. Therefore, extremely high
noise immunities are not needed; and the transmitter and receiver can be operated from the same
supplies as standard integrated logic circuits.
This article describes the operation and use of a
line driver and line receiver for transmission systems using twisted-pair lines. The transmitter provides a buffered differential output from a DTL or
TTL input signal. A four-input gate is included on
the input SO that the circuit can also perform logic.
The receiver detects a zero crossing in the differ·
ential input voltage and can directly drive DTL or
TTL integrated circuits at the receiving end. It also
has strobe capability to blank out unwanted input
signals. Both the transmitter and the receiver incorporate two independent units on a single silicon
chip.

Figure 2 shows a schematic diagram of the line
transmitter. The circuit has a marked resemblance
to a standard TTL buffer. In fact, it is possible to
use a standard dual buffer as a transmitter. However, the DM7830 incorporates additional features.
For one, the output is current limited to protect
the driver from accidental shorts in the transmission lines. Secondly, diodes on the output clamp
severe voltage transients that may be induced into
the transmission lines. Finally, the circuit has
internal inversion to produce a differential output
signal, reducing the skew between the outputs and
making the output state independent of loading.

FIGURE 2. Schematic Diagram of the DM7830 Line
Driver

As can be seen from the upper half of Figure 2, a
quadruple-emitter input transistor, Q9, provides
four logic inputs to the transmitter. This transistor
drives the inverter stage formed by Ql0 and Ql1

10-2

to give a NAND output. A low state logic input on
any of the emitters of Q9 will cause the base drive
to be removed from Ql0, since Q9 will be
saturated by current from R8, holding the base of
Ql0 near ground. Hence, Ql0 and Qll will be
turned off; and the output will be in a high state .
When all the emitters of Q9 are at a one logic level,
Ql0 receives base drive from R8 through the forward biased collector-base junction of Q9. This
saturates Ql0 and also Qll, giving a low output
state. The input voltage at which the transition
occurs is equal to the sum of the emitter-base turn
on voltages of Ql0 and Qll minus the saturation
voltage of Q9. This is about l.4V at 25°C.
A standard "totem-pole" arrangement is used on
the output stage. When the output is switched to
the high state, with Ql0 and Qll cut off, current
is supplied to the load by Q13 and Q14 which are
connected in a modified Darlington configuration.
Because of the high compound current gain of
these transistors, the output resistance is quite low
and a large load current can be supplied. Rl0 is
included across the emitter-base junction of Q13
both to drain 'off any collector-base leakage current in Q13 and to discharge the collector-base
capacitance of Q13 when the output is switched to
the low state. In the high state, the output level is
approximately two diode drops below the positive
supply, or roughly 3.6V at 25°C with a 5.0V
supply.
With the output switched into the low state, Q 10
saturates, holding the base of Q14 about one diode
drop above ground. This cuts off Q13. Further,
both the base current and the collector current of
Ql0 are driven into the base of Qll saturating it
and giving a low-state output of about O.lV. The
circuit is designed so that the base of Q 11 is
supplied 6 mA, so the collector can drive considerable load current before it is pulled out of
saturation.
The primary purpose of R 12 is to provide current
to remove the stored charge in Q 11 and charge its
collector-base capacitance when the ·circuit is
switched to the high state. Its value is also made
enough less than R9 to prevent supply current
transients which might otherwise occur' when the
power supply is coming up to voltage.

"Design Considerations for

a TTL Gate,

The lower half of the transmitter in Figure 2 is
identical to the upper, except that an inverter
stage has been added. This is needed so that an
input signal which drives the output of the upper
half positive will drive the lower half negative, and
vice versa, produci~g a differential output signal.
Transistors 02 and 03 produce the inversion. Even
though the current gain is not necessarily needed,
the modified Darlington connection is used to produce the proper logic transition voltage on the
input of the transmitter. Because of the low load
capacitance that the inverter sees when it is completely within the integrated circuit, it is extreme,
Iy fast, with a typical delay of 3 ns. This minimizes
the skew between the outputs.
One of the schemes used when dual buffers are
employed as a differential line driver is to obtain
the NAN D output in the normal fashion and provide the AND output by connecting the input of
the second buffer to the NAN D output. Using an
internal inverter has some distinct advantages over
this: for one, capacitive loads which slow down
the response of the NAND output will not introduce a time skew between the two outputs;
secondly, line transients on the NAND o~tPut will
not cause an unwanted change of state on the
AND output.
Clamp diodes, D 1 through D4, are added on all
inputs to clamp undershoot. This undershoot and
ringing can occur in TTL systems because the rise
and fall times are extremely short.
Output-current limiting is provided by adding a
resistor and transistor to each of the complementary outputs. Referring again to Figure 2, when
the current on the NAND output increases to a
value where the voltage drop across R11 is sufficient to turn on 012, the short circuit protection
comes into effect. This happens because further
increases in output current flow into the base of
012 causing it to remove base drive from 014 and,
therefore, 013. Any substantial increase in output
current will then cause the output voltage to collapse to zero. Since the magnitude of the short
circuit depends on the emitter base turn-on voltage
of 012, this current has a negative temperature
coefficient. As the chip temperature increases
from power dissipation, the available short circuit
current is reduced. The current limiting also serves
to control the current transient that occurs when

the output is going through a transition with both
011 and 013 turned on.
The AN D output is similarly protected by R6 and
05, which limit the maximum output current to
about 100 mA, preventing damage to the circuit
from shorts between the outputs and ground.
The current limiting transistors also serve to increase the low state output current capability
under severe transient conditions. For example,
when the current into the NAN D output becomes
so high as to pull 011 out of saturation, the output voltage will rise to two diode drops above
ground. At this voltage, the collector-base junction
of 012 becomes forward biased and supplies additional base drive to 011 through 010 which is
saturated. This minimizes any further increase in
output voltage.
When either of the outputs are. in the high state,
they can drive a large current towards ground
without a significant change in output voltage.
However, noise induced on the transmission line
which tries to drive the output positive will cut it
off since it cannot sink current in this state. For
this reason, D6 and D8 are included to clamp the
output and keep it from being driven much above
the supply voltage, as this could damage the
circuit.
When the output is in a low state, it can sink a lot
of current to clamp positive-going induced voltages
on the transmission line. However, it cannot
source enough current to eliminate negative-going
transients so D5 and D7 are included to clamp
those voltages to ground.
It is interesting to note that the voltage swing
produced on one of the outputs when the clamp
diodes go into conduction actually increases the
diffferential noise immunity. For example with
no induced common mode current, the low-state
output will be a saturation voltage above ground
while the high output will be two diode drops
below the positive supply voltage. With positivegoing common mode noise on the line, the low
output remains in saturation; and the high output
is clamped at a diode drop above the positive
supply. Hence, in this case, the common mode
noise increases the differential swing by three
diode drops.

Having explained the operation of the line driver,
it is appropriate to look at the performance in
more detail. Figure 3 shows the high-state output
characteristics under load. Over the normal range
of output currents, the output resistance is about
lOn. With higher output currents, the short circuit
protection is activated, causing the output voltage
to drop to zero. As can be seen from the figure,
the short-circuit current decreases at higher
temperatures to minimize the possibility of overheating the integrated circuit.

Figure 4 is a similar graph of the low-state output
characteristics. Here, the output resistance is about
5n with normal values of output current. With
larger currents, the output transistor is pulled out
of saturation; and the output voltage increases.
This is most pronounced at _55°C where the transistor current gain is the lowest. However, when
the output voltage rises about two diode drops
above ground, the collector-base junction of the
current-limit transistor becomes forward biased,

It is clear from the figure that the low state output
current is not effectively limited. Therefore, the
device can be damaged by shorts between the output and the 5V supply. However, protection
against shorts between outputs or from the outputs to ground is provided by limiting the highstate current.

providing additional base drive for the output transistor_ This roughly doubles the current available
for clamping positive common-mode transients on
the twisted-pair line_ It is interesting to note that
even though the output level increases to about
2V under this cdndition, the differential noise
immunity does not suffer" because the 'high-state

ability of the circllit to drive a differential load:
that is, the transmission line_ It can be seen that
for output currents less than 35 mA, the output
resistance is approximately l5n_ At both temperature extremes, the output falls off at high currents,
At high temperatures, this is caused by current
limiting of the high output state_ At low temperatures, the falloff of current gain in the lowstate output transistor produces this result_
Load lines have been included on the figure to
show the differential output with various load

the intersection of the output characteristic with

This is more than adequate for practical, twistedpair lines.

Figure 6 shows the no load power dissipation, for
one-half of the dual line driver, as a function of
frequency. This information is important for two
reasons. First, the increase in power dissipation at
high frequencies must be added to the excess
power dissipation caused by the load to determi ne
the total package dissipation. Second, and more'
important, it is a measure of the "glitch" current
which flows from the positive supply to ground

not properly designed, the current spikes in the
power supplies can become quite large; and the
power dissipation can increase by as much as a
factor of five between 100 KHz and 10 MHz. The
figure shows that, with no capacitive loading, the
power increase with frequencies as high as 10 MHz
is almost negligible. However, with large capacitive
loads, more power is required.
The line receiver is designed to detect a zero crossing in the differential output of the line driver.
Therefore, the propagation time of the driver is
measured as the time difference between the application of a step input and the point where the
differential output voltage crosses zero. A plot of
the propagation time over temperature is shown in
Figure 7. This delay is added directly to the propagation time of the transmission line and the delay
of the line receiver to determine the total datapropagation time. However, in most cases, the
delay of the driver is small, even by comparison to
the uncertainties in the other delays.

To summarize the characteristics of the DM7830
line driver, the input interfaces directly with standard DTL or TTL circuits. It presents a load which
is equivalent to a fan oyt of 3 to the circuit drivingit, and it operates from the 5.0V, ±10% logic
supplies. The output can drive low impedance lines
down to 50Q and capacitive loads up to 5000 pF.
The time skew between the outputs is minimized
to reduce radiation from the twisted-pair lines, and
the circuit is designed to clamp common mode
transients coupled into the line. Short circuit protection is also provided. The integrated circuit consists of two independent drivers fabricated on a
41 x 53 mil-square die using the standard TTL
process. A photomicrograph of the chip is shown
in Figure 8.

The variation of the internal termination resistance
with temperature is illustrated in Figure lS.Taking
into account the initial tolerance as well as the
change with temperature, the termination resis·
tance is by no means precise. Fortunately, in most
cases, the term ination resistance can vary
appreciably without greatly affecting the charac'
teristics of the transmission line. If the resistor
tolerance is a problem, however, an external resis·
tor can be used in place of the one provided within
the integrated circuit.

Figure 17 shows that the power supply current
also changes with common mode input voltage due
to the current drawn out of or fed into the supply
through R9. The supply current reaches a
maximum with negative input voltages and can
actually reverse with large positive input voltages.
The figure also shows that the supply current with

The interconnection of the DM7830 line driver
with the DM7820 line receiver is shown in Figure 19. With the exception of the transmission
line, the design is rather straightforward. Connections on the input of the driver and the output or
strobe of the receiver follow standard design rules
for DTL or TTL integrated logic circuits. The load
presented by the driver inputs is equal to 3 standard digital loads, while the receiver can drive a
worst-case fanout of 2. The load presented by the
receiver strobe is equal to one standard load.

The purpose of Cl on the receiver is to provide dc
isolation of the termination resistor for the transmission line. This capacitor can both increase the
differential noise immunity, by reducing attenuation on the line, and reduce power dissipation in
both the transmitter and receiver. In some applications, C 1 can be replaced with a short between
Pins 1 and 2, which connects the internal termination resistor of the DM7820 directly across the
line. C2 may be included, if necessary, to control
the response time of the receiver, making it
immune to noise spikes that may be coupled differentially into the transmission lines.

The effect of termination mismatches on the transmission line is shown in Figure 20. The line was
constructed of a twisted pair of No. 22 copper
conductors with a characteristic impedance of
approximately 170n. The line length was about
150 ns and it was driven directly from a DM7830
line driver. The data shows that termination resistances which are a factor of two off the nominal
value do not cause significant reflections on the
line. The lower termination resistors do, however,
increase the attenuation.

The effect of different values of dc isolation
capacitors is illustrated in Figure 22. This shows
that the RC time constant of the termination resis·
tor/isolation capacitor combination should be 2 to
3 times the line delay. As before, this data was
taken for a 150 ns long line.

Figure 21 gives the line-transmission characteristics
with various termination resistances when a dc
isolation capacitor is used. The line is identical to
that used in the previous example. It can be seen
that the transient response is nearly the same as a
dc terminated line. The attenuation, on the other
hand, is considerably lower, being the same as an
unterminated line. An added advantage of using
the isolation capacitor is that the dc signal current
is blocked from the termination resistor which
reduces the average power drain of the driver and
the power dissipation in both the driver and
receiver.

the transmitter looks like an open circuit to voltages reflected from the receiving end of the transmission line which try to drive it higher than its
normal dc state_ This cQndition exists until the
voltage at the transmitting end becomes high
enough to forward bias the clamp diode on the 5V
supply. Much of the phenomena which does not
follow simple transmission-line theory is caused by
this. For example, with an unterminated line, the
overshoot comes from the reflected signal charging
the line capacitance to where the clamp diodes are
forward biased. The overshoot then decays at a
rate determined by the total line capacitance and
the input resistance of the receiver.
When the ground on the receiver is 15V more
negative than the ground at the transmitting end,
the decay with an unterminated line is faster, as
shown in Figure 23b. This occurs because there is
more current from the input resistor of the
receiver to discharge the line capacitance. With a
terminated line, however, the transmission characteristics are the same as for equal ground voltages because the terminating resistor keeps the line
from getting charged.
Figure 23c gives the transmission characteristics
when the receiver ground is 15V more positive
than the transmitter ground. When the line is not
terminated, the differential voltage swing is increased, because the high output of the driver will
be pulled against the clamp diodes by the common
mode input current of the receiver. With a dc isolation capacitOT, the differential swing will reach this
same value with a time constant determined by the
isolation capacitor and the input resistance cif the
receiver. With a dc coupled termination, the characteristics are unchanged because the differential
load current is large by comparison to the common mode current so that the output transistors
of the driver are always conducting.
The low output of the driver can also be pulled
below ground to where the lower clamp diode con-

ducts, giVing effects which are similar to those
described for the high output. However, a current
of about g rnA is required to do this, so it does not
happen under normal operating conditions.
To summarize, the best termination is an RC combinat~on with a time constant approximately equal
to 3 times the transmission-line delay. Even
though its value is not precisely determined, the
internal termination resistor of the integrated circuit can be used because the line characteristics are
not greatly affected by the termination resistor.
The only place that an RC termination can cause
problems is when the data transmission rate
approaches the line delay and the attenuation
down the line (terminated) is greater than 3 dB.
This would correspond to more than 1000 ft. of
twisted-pair cable with No. 22 copper conductors.
Under these conditions, the noise margin can disappear with low-duty-cycle signals. If this is the
case, it is best to operate the twisted-pair line without a termination to minimize transmission losses.
Reflections should not be a problem as they will
be absorbed by the line losses.

CONCLUSION

A method of transmitting digital information in
high-noise environments has been described. The
technique is a much more attractive solution than
high-noise-immunity logic as it has lower power
consumption, provides more noise rejection, operates from standard 5V supplies, and is fully compatible with almost all integrated logic circuits. An
additional advantage is that the circuits can be
fabricated with integrated circuit processes used
for standard logic circuits.

The purpose of this appendix is to derive mathematical expressions describing the operation of the
line receiver. It will be shown that the performance of the circuit is not greatly affected by the
absolute value of the components within the integrated circuit or by the supply voltage. Instead, it
depends mostly on how well the various parts
match.

Finally, the threshold error due to finite gain in
the output stage can be considered. The collector
current of 07 from the bleeder resistor R 14, is
large by comparison to the base current of oa, if
oa has a reasonable current gain. Hence, the collector current of 07 does not change appreciably
when the output switches from a logic one to a
logic zero. This is even more true for 06, an
emitter follower which drives 07. Therefore, it is
safe to presume that 06 does not load the output
of the first-stage amplifier, because or the compounded current gain of the three transistors, and
that oa is driven from a low resistance source.
It follows that the gain of the output stage can be
determined from the change in the ernitt~r-base

Secondly, when the analog signals on some channels are positive and those on other channels are
negative, the negative currents will subtract from
the positive currents, further reducing the total
leakage at the output. Also, when a switch is ON,
it would not be contributing to the leakage.
Assuming signal voltages vary randomly between
+10 and -10V, total leakage will run about half
that of worst case. Of course, leakage will be still
less if the analog signal limits are less tt-an ±10V.
CONCLUSION
Integrated MOSFET switching circuits make excellent low-level analog commutators.' Power dissipation is essentially zero, capacitance is reasonably low (typically 8 pF at the analog input), the
ROFF/RoN ratio is high, and the control signal is
isolated from the input. MOS IC's with four or
more switching channels are readily available in
production quantities.
Conventional bipolar drive circuitry can control
channel switching at rates in the megahertz range.
Hybrid integrated circuits containing monolithic
MOS multiplexers and bipolar drivers are being
manufactured for medium-speed applications
(NH0014 and NHOO19). Level-changing circuits in
these devices allow external TTL or DTL IC's to
control the commutator at analog signal levels to
±10V. MOS commutator systems can be built with
building-block circuits such as the MM454F in
Figure 12. This monolithic IC can commutate at
rates to 1 MHz, depending on the range of signal
voltages. The control logic on the chip includes a

FIGURE 12. Logic Diagram of MM454F Four-Channel
MOS Multiplexar. Switches and Control
Circuitry Are Fabricated In the Same Monolithic Chip.

MOSFET switches are generally used to commutate low-frequency analog signals. Today, the
preferred device for RF-signal multiplexing is the
N-channel junction FET, which can handle signal
frequencies in the VHF range. MOS IC's have operated successfully, however, in some RF application. The high-frequency capabilities of MOS IC's
are being investigated by the author and will be
the subject of a future report.
Although the most outstanding feature of
MOSFET's is the ease with which they can be fabricated as multichannel monolithic IC's, their electric81 characteristics compare quite favorably with
those of other switching components. An "order
of magnitude" comparison of MOSFET's and
other devices that could be used for lOW-level
analog switching is given by Table 1. Better characteristics might be obtained in each case, but
these values are typical.
Each type of analog switch has advantages and
limitations that must be considered for practical
use. No switch is perfect. If a switch were perfect,
it would have zero resistance when ON, infinite
resistance when OFF, and be 100% efficient-that
is, it would consume no power.
Electrically, the mechanical switch comes close to
this ideal. It has the highest ROFF/RoN ratio and
totally isolates the analog signal from the switching-control function. However, it has mechanical
drawbacks that make it noisy and unsuitable for

10-22

low-level commutation: contact bounce, contact
pitting, susceptibility to vibration, and the necessity to move a physical mass to turn the switch on
or off. It cannot commutate very fast and consumes more power than a solid-state switch, as a
rule_
Bipolar transistors make excellent digital switches,
the fastest ever developed, but they are usually a
poor choice for multiplexing low-level analog
signals. Their main disadvantages are an inherent
offset voltage and the impossibility of isolating the
switching control signal from the analog signal
being switched. Furthermore, analog switching
rates are slower than FET's. Their Ron is low,
though-typically 10 ohms in, analog switches
(versus milliohms in power transistors). Bipolar
transistors fare much better in high-level switching,
where DC offset is not a problem.
Photocells make fairly good analog switches.
Because light is used as the control signal, the control is completely isoillted from the analog electrical signal. However, Ro N is high and the
ROFF/R ON ratio is relatively poor. Even at
moderate RO~F/RoN ratios, photocells cannot
commutate much faster than 100 Hz. After exposure to intense light, a photocell made with a
semiconductor such as cadmium sulfide or cadmium selenide exhibi~ a long turn-off decay time.
Photocell turn-off time constants may stretch out
for many seconds before Ro F F reaches an acceptable level. Faster switches can be made with combinations of electroluminescent diodes and phototransistors, but these devices are still very
expensive.
Some N-channel junction FET's come close to
being ideal switches. Offset voltage is zero, and the
admittance-ta-input capacitance ratio Yh/C". is
the highest of any contemporary device. These
two parameters govern commutation rate, which
can be very high if the impedances of the signal
source and the load are made very low. Theoretically, the high majority-carrier mobility in an
N-channel J-F ET enables it to operate at a frequency higher than any other tyPe of FET. A
good example is the 2N4391: ROFF/RoN is
about 109 , Rd. (on) is a maximum of 30 ohms,
and maximum leakage at 2SoC is 100 pA. The orle
major disadvantage of N-channel J-FET's is that
they are extremely difficult to make in the form
of multichannel IC's. For high-frequency commutation, the P-channel type of J-FET is a !,loor
choice because its majoritv carrier mobilitY is
lower than N channel J-F ET' s.

ABSTRACT
This discussion begins with some basic commutation circuits, then describes some uses in linear
amplifier applications such as reset fllnctions and
chopper applications. The use of MOS switches as
a suppressed carrier double-sideband modulator
and a double-sideband demodulator is then covered; followed by a circuit proposal for a phaselocked loop AM-FM detector without tuned
circuits.
THE MOS DIFFERENTIAL SWITCH-DC TO RF
The dual differential switch is a particular switch
connection scheme wh ich at first glahce prompts
one'to say-so what? It is, however, one of those
simple circuit configurations which can find a wide
variety of uses in electronic circuits. The dual differential switch could also be called a DPDT
switch or two SPDT switches-depending on how
they are toggled.
MOS switches have some unique features which
make them very useful for data switching' ,2,3: no
offset voltage, high Ro F F IRa N ratios, low leakage, fast operation, and matched "on" resistance.
Within definite bounds, MOS switches exhibit
good isolation between the switching drive and
signal path.

MOS switches do have somewhat unique driving
,requirements. In order to solve this problem,
National manufactures a hybrid integrated circuit
which' provides DTL-TTL drive compatibility with
the dual differential switch. These devices use the
DM7801 chip with an MM450 chip for the
NHOO14 and the DM7800 chip with an MM450
chip for the NH0019. The NH0014 is basically a
DPDT switch while the NH0019 is two SPDT
switches in the same package. Each connection has
its particular advantages and disadvantages.
COMMUTATION CIRCUITS
The NH0014 may be used as a two channel como'"~
mutator only, because two of its four channels are
always on. The NH0019 may be used for systems
with any number of channels since it can shut all
channels off on command.
Figure 3 shows a six channel commutator which
'may be easily expanded. Data sampling may be
done on any format wh ich the user chooses. Sampling format is easily controlled by DTL or TTL
logic design independent ,of the NH0019. Since
each bllffer-driver of the NH0019 has a dual input
gate, all channel blanking is readily achieved. If
desired, the format shown in Figure 3 may be

figuration. Demultiplexing may be accomplished
by using a circuit identical to the multiplexer
because the MOS device is a true bilateral switch.
In hard·wired systems where the multiplex "out·
puts" are electrically connected as in Figure 4, the
signal may be transmitted in either direction. For
non·hardwired systems, the modulation·demodula·
tion sequence is still bilateral, but provisions must
be made for transmit/receive function control.

Since the multiplexed information is in differential
form, common mode noise' is greatly reduced.
Also, the MOS gate drive spiking is drastically
reduced because of the differential channel con·

USAGE IN LINEAR AMPLIFIER CIRCUITS
The NH0014 and NH0019 devices are useful for
switching functions in linear circuit applications
because of high off/on resistance ratio and ease of
switching control using logic elements. Sample and
hold circuits, integrator reset switching, and reset
stabilized amplifiers are a few examples (Figure 5).
More detailed information on this type of circuitry
is available in National Semiconductor applications
notes AN-4, AN-5, AN-20, and AN_29 4 - 7 •
An obvious use of the NH0014 and NH0019 are in
chopper stabilized amplifiers (Figure 6). One of
the better forms of chopper stabilized amplifiers is
the series shunt chopper with sample and hold
type of output. The NH0014 does a good job at
this because it contains the complete set of
switches plus proper drive for the switches. The

NH0014 can greatly reduce component count for
chopper stabilized amplifiers.

DOUBLE SIDEBAND MODULATOR
The NH0019 can be used as a double sideband
mo.;ju lator. In modu lator applications, the
NH0019 functions as a DPDT switch which alternately reverses the polarity of the modulating
signal at the chopper frequency. MaS switches
work quite well at this application because of zero
offset voltage and large signal handling ability.
In order to build a double sideband balanced
modulator8 ,9, one of the two modulating inputs
must be applied as a balanced input. For the circuit shown in Figure 7, an LM102 and LM107
were used for an audio phase splitter.

Both point A and point B in Figure 7 are DSB
modulated outputs; so, technically, you could get
by with only one. The waveform at point A is
illustrated in Figure 8a for a carrier frequency of
100 kHz and an audio frequency of 12.5 kHz.
Point B is equal and out of phase.
One type of spurious response encountered with
MaS switching devices is output spikes caused by
a charge being dumped into the channel by the
gate drive through gate·channel capacitance. By
adding Cl, part of the charge can be absorbed,

the switching transients are an "in phase" or
"common mode" error.

To better illustrate th'e improvement by using a
balanced output, the audio signal was reduced to
zero volts and the points A, B, and AB were mea·
sured as shown in Figure 9. The improvement
operating in the differential mode is oDvious.
The circuit drive requirements for Figure 7 may be
simplified by using the NH0014 since it provides
an inverting function internally. Only one phase of
toggle drive to the NH0014 is required.

thus reducing the voltage ampl itude of the spikes.
The R1Cl combination has its 3 dB point at about
80 kc, so output from the phase splitter was not
attenuated in the audio range.
The astute observer will notice switching transients
on the waveform in Figure 8a. By taking the out·
put in differential form at points A and B, these
transients are greatly reduced because the desired
signals are equal but of opposite polarity, while

The modulation will be distorted more due to the
phase lag created by the internal inverter of the
NHOOI4. Figure lOa shows the switching perform·
ance of the NH0019 while Figure lOb shows the
switching performance of the NHOOI4. In applica·
tions which do not require high carrier fre·
quencies, the N H0014 is adequate, but for carrier
frequencies above 100 kHz, the NH0019 provides
improved performance because of its symmetrical
switching behavior.

FIGURE 11. Demodulator Recovered Output

DOUBLE SIDEBAND DEMODULATOR

The major requirement of double sideband signal
demodulation is proper carrier reinsertion. For
maximum output, the carrier must be reinserted
exactly in phase or exactly 1800 out of phase with
respect to the signal. Any departure from th is
optimum phase relationship will reduce the reo
covered signal amplitude. By applying the double
sideband signal to a second N HOOl g, as shown in
Figure 7, the original modulating waveform may
be recovered, along with some switching transients
(Figure 11).
10·28

These switching transients may be filtered out
quite easily. It is, however, instructive to compare
the recovered audio signal with the original. The
modulating signal had less than 0.1% distortion at
1 kHz. Figure 12 shows the distortion of the
recovered signal vs. signal amplitude.
Carrier frequency was 100 Hz for the upper curve
and 10k Hz for the lower. These curves indicate
that most of the distortion is due to switching
transients, especially at low modulation levels.
Output filtering will significantly reduce the reo
covered signal distortion.

Figure 13 emphasizes the affect that switching
transients have on harmonic distortion. At carrier
frequencies below 10 kHz, the RMS value of the
transients is reduced to a point where distortion of
the MOS switches themselves can be seen.
The NH0014 and NH0019 data sheet suggests a
V plus supply value of 10 volts and a V minus
supply value of -20 volts. However, switching
transients may be reduced by using different power
supply voltages. Figure 14 and Figure 15 show what
happens to harmonic distortion caused by spiking
versus power supply level. Figure 14 is plotted for
V minus with V plus at 10 volts. Figure 15 shows
what happens as V plus is varied. All of the pre·
vious data was taken at V plus at 14 volts and V
minus at -12 volts.

AM-FM DEMODULATOR
Although an AM·FM demodulator was not
physically constructed, the previously discussed
"double sideband demodulator" performance
implies that a very interesting phase detector can
be built. The interesting features of this type of a
detector are large dynamic range, recovery of both

Figure 16 shows the proposed circuit block diagram which uses a phase-locked loop for phase
reference signal. The voltage controlled oscillator
(VCO) is operated at 4 f o . Flip Flop #1 provides a
two phase output which is fed into FF #2 and
FF #3. The outputs of FF #2 and FF #3 are
exactly 900 out of phase regardless of the frequency of the VCO. This kind of performance is
awfully hard to achieve using tuned clrcu its. For a
455 kHz detector, the VCO would operate at
1820 kHz. TTL flip flops will operate quite nicely
at that frequency and shou Id hold phase sh ift
errors to practically zero. The LM 107 provides DC
gain to close the phase-locked loop, it forces the
VCO to a frequency and phase angle which causes
the "FM out" port to zero volts DC; this port is
then operating exactly in quadrature with the
applied signal. This part of the detector is then
insensitive to amplitude modulation and sensitive
to frequency modulation. Since the AM detector
portion is operating exactly 90 0 out of phase with
the FM portion, its output is insensitive to FM and
sensitive to AM.

CONCLUSION

The most obvious use of the NH0014 and NH0019
is in commutator applications, and it indeed is a
very useful device for that purpose. The use of
these switches in linear circuit applications is also
very attractive because of DTL· TTL control com·
patibility. There are many more uses of these
switches possible than the few examples described
here.
The unusual application of these devices as sup'
pressed carrier double·sideband modulators and
demodulators suggests applications in servo systems
and even communications systems due to their
high speed operation. The final circuit suggestion,
a phase·locked loop AM·FM demodulator without
tuned circuits should be very useful in communica·
tions systems. The NH0019 will operate quite well
at an IF frequency of 455 kHz or less.
These basic capabilities of the MOS dual differen·
tial switch should encourage much greater usage
of this type of device in new product' designs.

PIN DIODE DRIVERS

INTRODUCTION
The DH0035/DH0035C is a TTL/DTL compatible,
DC coupled, high speed PIN diode driver. It is
capable of delivering peak currents in excess of
one ampere at speeds up to 10 MHz. This article
demonstrates how the DH0035 may be applied to
driving PI N diodes and comparable loads which
require high peak currents at high repetition rates.
The salient characteristics of the device are summarized in Table I.

There are essentially two considerations of interest
in the "ON" condition. First, the amount of
"ON" control current must be sufficient such that
R F signal current will not significantly modulate
the "ON" impedance of the diode. Secondly, the
time required to achieve the "ON" condition must
be minimized.

In terms of Rp, equation (15) becomes:

Rp =

Again, the power dissipated by the DH0035 must
be considered. In the "OFF" state, the power
dissipation is given by:

For the circuit of Figure 6, and IDC = 100 rnA,
Rp is 62 ohms (nearest standard value).
It now remains to select the value of C,. To do
this, the change in voltage across C, must be
evaluated. In the "ON" state, the voltage across

In the "OFF" state, Vc is given by:

Total power dissipated by the DH0035 is simply
PON + POFF . For a 50% duty cycle and the circuit of Figure 6, P diss = 616 mW.

The peak turn-off current is, as indicated earlier,
equal to 50 rnA x hfe which is about 1000 rnA,

current through 0 5 drops to the diodes leakage

HIGH SPEED ANALOG SWITCHES

SUMMARY
In the past, many factors combined to make
precision, high speed analog switching circuits complex and expensive, if not impossible_ A unique
monolithic J-FET family opens new analog switching applications which require high toggle rates,
high frequency signal handling ability, and high
level analog signals with broad dynamic range_
Called the AM 1000, AM100l and AM1002 analog
switches, these devices were developed specifically
for high speed analog switching applications_ The
AM 1000 series overcomes the probl em of slow
switching speed normally associated with junction
FET analog switches_ While MOS analog switches
are noted for their high speed, they have the
peculiar problem of their ON resistance being
modulated by the analog signal leveL The AM1000
series eliminates this problem too_
National's AM1000 series analog switches are
simple N-channel monolithic integrated circuit
J-FETs. They are packaged in TO-72 (4-pin TO-1S)
headers to reduce circuit board space and yet
retain the advantages· of a hermetically sealed
package.
WHAT IS AN ANALOG SIGNAL?
An analog signal is an electrical voltage (or
current) whose level is an analog of certain information. This information can be an electrical
level itself, a voice signal, an electrical analog
of a pressure, temperature, position, etc., or any
other data source. The analog information may
also be preconditioned by logarithm ic compression or expansion, or other desired "distortion_"
If the analog information does not vary quickly
with time and if many analog signals have to
be handled in a system, the analog information
. may be sampled periodically rather than monitored
continuously_ Sampled data systems can dramatically reduce cost and weight by proper utilization
of available information channel bandwidth where
the cost of additional data channels becomes
expensive.

The telephone companies are probably the most
adept at signal multiplexing, but other applications
are beginning to appear. Modern aircraft are using
multiplexing to reduce weight in wire harnesses.
Any applications requiring long multiconductor
cable runs are prime targets for economic use of
analog signal mUltiplexing.
TIME DOMAIN MULTIPLEXING
There are two basic types of mUltiplexing: frequency domain multiplexing and time domain
multiplexing. Frequency domain multiplexing is
common in RF communications, it uses a number
of subcarriers on a data channel, each subcarrier
being modulated in some manner. An example
would be FM radio standard broadcast which has
home stereo mu Itiplex information (a suppressed
carrier double sideband subcarrier) and the SCA
commercial "background music" multiplex information (an FM modulated subcarrier). When
the number of data channels becomes great, frequency domain multiplexing becomes difficult to
implement.
In time domain multiplexing, a certain time slot
is allowed for sampling of a particular data line.
Thus, if you sample some analog information
during a 10 j.ts time slot at a 10kHz rate, you
have time "left over" to sample nine other signals
at 10 j.ts intervals at a 10 kHz rate. If you can
improve the analog switch device to execute a
suitable sample in only 1 j.tS, you have made a
tenfold improvement and you have th e choice of
increasing system channel capability to 100 channels (with no change in analog signal bandwidth),
increasing analog signal frequency bandwidth by
10 times (with no increase in channels), or a compromise between increasing signal bandwidth and
increasing the number of data channels. This is
what the AM 1000 family of analog switches is
all about; they allow shorter sampling times for a
given signal accuracy.

WHAT MAKES A GOOD ANALOG SWITCH?
There are five principle parameters wh ich determine how good an analog switch is:

There is at least -10V from gate to source of 0 1
so it is pinched off and leakage from .input to
output is in the pA range. O 2 has -10V from gate
to source so it is also pinched off and its current
which shunts the input signal is in the pA range_

ON resi sta nce
ON resistance modulation
OFF resistance
Offset voltage
Commutation rate
There are other considerations which may also be
significant for special cases, but these five will
almost always have significant bearing on a system
design. For most applications, there are two devices which are the most popular-MaS switches
and J-FET switches. Relays normally would be
a good choice but they won't toggle very fast.
In general, the MaS switches have had a speed advantage, and ease of fabrication advantage, whereas the J-FET switches have an advantage of lower
ON resistance, no ON resistance modulation, higher
voltage capability.4.5,6 The AM1000 family of
analog switches have all of the advantages of the
J-FET plus high speed which makes it superior to
any MaS switch in a precision system.
WHAT MAKES THE AM1000 FAST?
Figure 1 shows a typical J-FET circuit used in
analog switching. Diode 0, allows the gate drive
signal to drive the gate negative thus turning off
the J-FET switch. When the gate drive signal goes
positive, diode 0 1 decouples the drive from the
gate and resistor Rg discharges the gate-source
capacitance. Rg ml,lst be large so it doesn't load
the analog signal, typical values for Rg are 100 kn
and up; thus the gate capacitance:-Rg time constant is large which precludes high switching rates.
If Ciss of the J-FET is 15 pF nominal and Rg is
100 kn, the time constant is 1.5 p.s thus making
megacycle toggle rates impossible.

FIGURE 3_ AM1000 Turned Off

0 3 is operated at OV gate-source so it draws saturation current, loss. The bias supply for 0 1 must be
10V more positive than the negative drive signal.
During turn-on, the drive signal ideally makes a
step function change from -20V to +10V thus
turning O2 off. The gates of 0" O2 and 0 3 are
then driven positive by the saturation current of
0 3 through diode 0,. The rate that this voltage
slews is dependent on gate capacitance and loss
of 0 3 . C;ss(off) of the AM 1000 is about 10 pF so

FIGURE 1. Typical J-FET Analog Switch

The AM 1000 consists of three J-FETs. One large
and two small ones. The large one acts as the
analog signal pass transistor. The two smaller
FETs act as a turn-on circuit which reduces
switching transients.
The pinchoff voltage of all these FETs are almost identical and are all less than 10V_ In Figure :3 (ignoring diode drops). the gates of all three
FETs are at -20V and the AM1000 is turned off.

Within 5V of rise (about 10 ns). O2 begins to turn
on and 0 1 turns off_ The remainder of the gate
capacitance charge is discharged into the input
(or source) of 0 1 via the ON resistance of O2 and
0 3 , During this time interval the average series
resistance of O2 and 0 3 is about 2 kn and the
gate capacitance is changing from about 10 pF
to about 25 pF. The approximate RC time constant is 20 pF and 2 kn, or 40 ns, depending on
the level cif the analog signal. Total turn on time
is therefore about 50 ns. For a +10V analog
signal, the correct analysis is a little more complex,
but the AM 1000 will turn on in about 70 ns for
this circuit'condition. The reason that the turn-on
transier)t at R L is drastically reduced is that the
discharge path . of gate capacitance does not flow
through R L. The small transient that may appear
at R L is due to the time that Dl is on during
turn-on.

Gate capacitance discharge path

FIGURE 4. AMI 000 Turning On

So, the AM 1000 achieves its high switching speed
because its Rg (see Figure 1) is very low during
turn on, yet its Rg during the OFF state is in the
G ohm range and thus doesn't load the signal.

The capacitance of the AM 1000 is about twice that
of the MOS switch but the system load resistance
is 25 times lower thus giving the AM 1000 a toggle
rate advantage of about 12 times over the MOS
"high speed" analog switch. In order to graphically
illustrate the superiority of the AM 1000, two
simple series switches were constructed; one with
the MOS switch and one with an AM 1000. The
MOS analog switch was set up to sample a +10V
DC signal, after being switched off, the output
returns to ground level. The AM 1000 was set up
to sample a portion of the turn off transient of
the MOS analog switch, each switch with a 0.5%
system accuracy! Figure 5 shows the circuit used
to obtain the oscillograph shown in Figure 6A.

TOGGLE RATE
The toggle rate (how fast the switch can be turned
on and off) of an analog switch is not a simple
straightforward parameter for a real system design.
The reason is that most analog switches are speci·
fied at a ridiculously low impedance level; this is
done in order to show the highest speed that the
device can possibly go. This speed is not normally
realistic for most systems designs. In order to
demonstrate a realistic comparison, the AM 1000
will be pitted against an MOS analog switch for a
system with a ±10V analog signal swing.

ROSlon) and Ciss indicate the basic speed capability
of the devices assuming low source and load
impedance, here the AM 1000 has a speed advantage
of about 5: lover the MOS switch.
The parameter that affects toggle rate the most,
however is ROSlon) variation with analog signal
level. At an analog signal of +10V, the MOS
switch has an. ROSlon) of 150n and for a -10V
analog signal it has an on resistance of 400n. This
variation of ON resistance is caused by the bulk
gate to channel voltage modulating the ON reo
sistance of the MOS switch. 5 Thus, the MOS
switch has a design on resistance characteristic of
275n ±125n. The AM1000 has an ROSlon) of 25n
±5n and its resistance does not vary with analog
signal level.
For a system of a given accuracy, the load imped·
ance is determined by the variations expected in
channel resistance. Assuming a system accuracy of
±0.5%, the AM 1000 load resistance cou Id be as
low as 1 kn; the MOS switch load resistance would
have to be 25 kn (±125n being 0.5% of 25 kn).

A National LH0033 high speed buffer was used
to sense the analog voltage at the load resistor of
the MOS switch and drive the analog input of the
AM1000. Figure 6A shows the oscillogram; the
upp~r trace is the MOS switch turning off; its load
voltage heading toward ground; the lower trace
(oscilloscope vertical gain reduced slightly for
photo clarity) shows the AM 1000 sampling this
switching transient. Figure 68 shows the timing
pulses, the upper trace being the MOS drive timing
and the lower is the AM1000 drive timing (posi·
tive indicating off for both devices). It is interesting
to note that the turn·on delay or "aperture time"
of the AM 1000 is primarily caused by the DH0034
translator. Maximum specified turn on time is
100 ns and turn off time is specified at 100 ns for
the AM 1000. Figure 6 shows absolute superiority
of the AM 1000 in switching ability for a given
system accu racy.
AM1000 DRIVE CIRCUITS
Normally, analog switches will be selected by some
digital control means which will usually mean OV
add +5V power supply levels. The AM t 000 needs
a driver capable of handling the full analog voltage
swing, plus 10V. Therefore a circuit known as an
analog switch translator is normally requried. There
are several types available. All of the following
circuits feature "break before make" action which
is desirable for multiplexing.

Analog switch translator·drivers fall into two basic
categories. Those with pullups and those without.
If the translator-driver has a pullup, such as the
National DM7800, then a switching diode must be
used to decouple the driver from the AM 1000
when the driver goes positive.

In some systems, the cost of monolithic or hybrid
drivers is not worth the space they save. Figure 9
shows a four channel driver using low cost discrete
components. The ON channel is selected by binary
coding and is DTL-TTL compatible. If A and B
are "high" then drive is removed from Q 5 allowing
channell AM100l to pull up and turn on. Q6, Q 7
and Q s have drive applied which pull down on
CH2, 3 and 4 thus turning them off. The voltages

CURRENT MODE MULTIPLEXING
So far, the discussion of multiplexing circuits has
been confined to sampling various analog input
voltages. Voltage mode analog switching allows
maximum toggle rates but limited voltage range
(±10V for AM 1000, AM1002 and ±15V for
AM100l).
If large analog voltages must be handled, current
mode multiplexing must be used; toggle rate is
reduced because accurate current-voltage converters are not as fast as non-inverting voltage amplifiers. Analog signal loading can also be a problem.
Nevertheless current mode multiplexing allows
sampling of very high analog voltages. This is
accomplished by using scaling resistors and bound
limit diodes at the input of the analog switch.
Also, in this case the current to voltage converter
should be the lowest impedance point in the
system, so the AM 1000 must be "turned around",
so its analog "output" is used for the signal input
and vice versa.

The 10 kSl feedback resistor shown results in 10V
output for 1 mA input. Thus the scal ing resistor at
the input is selected for 1 mA for 100V input, or
10 IlAN. A 1000V analog signal would use a
1 MSl scaling resi!;tor. For lower voltage signals,
the Ron of the AM1000 would have to be ~on·
sidered for precision systems. The bound limit
diodes connected to +10V and -10V prevents
excessive voltage from appearing at the AM1000.
Input impedance to the current to voltage converter is Rt divided by the open loop op amp gain
(5000 for the LH0032); the input impedance
would be 2Sl in Figure 10.
OTHER APPLICATIONS
Analog computer circuits can make good use of
analog switches. A few examples are sample and
hold circuits, reset stabilized circuits, integrator
reset switches, and chopper stabili~~ed amplifiers. 4
Video signal switching can be done with a minimum of switching transients. More unusual appli·
cations such as double sideband suppressed carrier
modulators can be constructed plus double sideband suppressed carrier demodulation and FM
quadrature demodulators. 5
CONCLUSION
Where precision, high speed analog switching is
required, the AM1000 series of analog switches
"rewrites the book."

FIGURE 10. Current Mode Multiplexing

The system sensitivity in Figure 10 is determined
by Rt in the current to voltage converter op amp.
The LH0032 J·FET input op amp is selected
because of its high slew rate and low input current.

Time domain multiplexing can be dramatically
improved in channel capability and/or analog signal
bandwidth capability. Sample and hold circuits can
be improved, chopper stabilized amplifiers can be
improved and virtually any other circuit which
requires precision, high level, high speed analog
switching can be improved.

INTRODUCTION

MOS memories present unique system and circuit
challenges to the engineer since they require precise timing of input wave forms. Since these inputs
present large capacitive loads to drive circuits, it is
often that timing problems are not discovered
until an entire system is constructed. This paper
covers the practical aspects of using modern clock
drivers in MOS memory systems. Information
includes selection of packages and heat sinks,
power dissipation, rise and fall time considerations,
power supply decoupling, system clock line ringing
and crosstalk, input coupling techniques, and
example calculations. Applications covered include
driving various types shift registers and RAM's
(Random Access Memories) using logical control
as well as other techniques to assure correct
non-overlap of timing waveforms.

The MH0026 is a high speed, low cost, monolithic clock driver intended for applications above
one megacycle. Table II illustrates Its performance
characteristics while its unique circuit design is
presented in Appendix II. Of course the above are
just examples of the many different types that
are commercially available. Other National Semiconductor MOS Interface circuits are listed in
Appendix III.
The following section will hopefully allow the
design engineer to select and apply the best circuit
to his particular application while avoiding common
system problems.

Of course each of us is careful of details but
reminders such as "turn on the power suppl ies"
or "don't reverse supply polarity" sometimes
solve a not-so·obvious problem. This section is
intended to review and answer deSign questions
like "how much should I decouple supplies?"

The MH0025 was the first monolithic clock driver.
It is intended for applications up to one megacycle
where low cost is of prime concern. Table I
illustrates its performance while Appendix I describes its circuit operation. Its monolithic, rather
than hybrid or module construction, was made
possible by a new high vOltage-gold doped process
utilizing a collector sinker to minimize V CE SAT.

Package and Heat Sink Selection
Package type should be selected on power handling
capability, standard size, ease of handling, availability of sockets, ease or type of heat sinking

Bleed resistors are connected between the clock
driver and ground causing a current of a few mA
to flow. The output impedance of the clock driver
is reduced and the negative spike is thus minimized.
Values for Rb depend on layout and the number
of registers being driven. Typical values are between
lk and 10kn.
A major point should be emphasized with regard
to clock·line crosstalk, i.e., even if the output
impedance of the driver is zero ohms, self inductance between the clock dnver and registers will
cause the clock lines to spik~ on the transitions.
Hence, the technique shown in Figure 6 works
reasonably well for small systems.

For large systems, the circuit of Figure 7 is

Input Capacitive Coupling

Generally, MOS shift registers are powered from
+5V and -12V supplies. A level shift from the
TTL levels (+5V) to MOS levels (-12V) is there·
fore required. The level shift could be made utiliz·
ing a PNP transistor or zener dIode. The disadvan·
tage to DC level shifting is the increased power
dISSIpation and propagation delay in the level
shifting device. Both the MH0025 and MH0026
utilize input capacitors when level shifting from
TTL to negative MOS capacitors. Not only do the
capacitors perform the level shift function without
inherent delay and power dissipatIon, but as will
be shown later, the capacitors also enhance the
performance of both the MH0025 and MH0026.

When the output of the TTL driver goes high,
current is supplied to the base of 0" through
C,N , turning it "ON." As the collector of 0, goes
negative, O2 turns OFF. Diode CR 2 assures turn-on
of 0, prior to O2 's turn·off minimizing current
spiking on the V+ line, as well as providing' a low
impedance path around 02'S base emitter junction.

The negative voltage transistion (to MaS logic "1 ")
will be quite linear since the capacitive load will
force 0 1 Into Its linear region until the load is
discharged and 0 1 saturates. Turn-off begins when
the input current decays to zero or the output of
the TTL driver goes low. 0 1 turns "OFF" and O2
turns "ON" charging the load to within a V BE of
the V+ su pply.
Rise Time Considerations
The logic rise time (voltage fall) of the MH0025 is
primarily a function of the AC load, CL , the
available input current and total voltage swing. As
shown in Figure AI-2, the input current must

Equation (AI-5) may be used to predict t, as a
function of C L and t:.V. Values for CTC and hFE
are 10 pF and 25 respectively. For example, if a
DM7440 with peak output current of 50 mA were
used to drive a MH0025 loaded with 1000 pF, rise

MH0025 Input Drive Requirements
Since the MH0025 is generally capacitively coupled
at the input, the device is sensitive to current not
input voltage. The current required by the input is
in the 50 to 60 mA region. It IS therefore a good
idea to drive the MH0025 from TTL line drivers,
such as the DM7440 or DM8830. It is possible to
drive the MH0025 from standard 54/74 series gates
or flip·flops but tON and tr will be somewhat
degraded.

The schematic of the MH0026 IS shown in Figure
All-I. The device is typically AG coupled on the
input and responds to input current as does the
MH0025. Internal current gain allows the device
to be driven by standard TTL gates and flip-flops.
With the TTL input in the low state 0" O 2 , 0 5 ,
Os, and 0 7 are "OFF" allowing 0 3 and 0 4 to
come "ON." Rs assures that the output will pull
up to within a V BE of V+ volts. When the TTL
input starts toward logic "1," current is supplied
via G'N to the bases of 0, and O 2 turning them
"ON." Simultaneously,' 0 3 and 04 are snapped
"OFF." As the input voltage rises (to about 1.2V).
0 5 and Os turn-on. Multiple emitter transistor 0 5

0 4 were rapidly turned OFF minimal power supply
current spiking will occur when 0 7 comes "ON."

If DC operation to a negative level is desired, a

Not much need be said about the EIA RS232C
designs. They meet or exceed a standard wh ich is
below today's attainable performance levels.

UNIFIED BUS
A typical unified bus is a flat, multiconductor
cable interconnecting the CPU and peripherals ot'
a minicomputer (Figure 2). The lines are single·
ended (non·differential), ground-referenced, bidirectional, and terminated at each end in 1200.
to 3.2V. The line level is high except when an
open-collector driver pulls the line low. Drivers
take turns transmitting, as controlled by "polling"
or other control sequences.
Single-ended communications are susceptible to
common mode voltage induced by ground currents
between chassis. In a computer room, the problem
is usually minimized by linking the chassis with
heavy-gauge grounding cables. Communications
with remote points go through differential transmission links, or modems coupled to phone lines.
In early unified bus designs, open-collector TTL
buffers were used as drivers, and standard gates
as receivers. However, the low threshold voltage of
the receiving gate (it can be as low as 1.0V) is too
close to ground potential, which can itself be
carrying transients of almost a volt. In addition,
the gate's input current can be as high as 1.6 mA,
severely limiting the number of receivers which
can be controlled by one driver. This is true
particularly if the driver has an open collector output, and must also be sinking the current from a
1200. termination at each end of the unified bus.
That problem was solved by the SP380 gate. Its
signal input is the base of an NPN emitter-follower,
giving a higher threshold and lower input current.
Unfortunately, the input transistor's collector-base
junction becomes forward-biased when Vcc goes
down. If a peripheral is shut off, the bus lines are
clamped near ground unless the bus cable is
disconnected manually.

The new unified bus designs in Table I have a
receiver that is self-isolating when power is down.
The main bus is still usable if peripherals are
turned off.
Other improvements incluc\e: very low input
current, typically 151.1A whether Vee is 5.0V or
zero; input hysteresis of 1.0V, providing 1.8V
noise immunity; thresholds of 1.3V and 2.3V; and
temperature compensation to keep thresholds and
noise immunity constant.
The DM7836/DM8836 is pin-compatible with the
SP380. Each receiver trio in the DM7837/DM8837
has an enable control, so the system can force
receiver outputs to zero whether the bus is pulled
down or not. The four drivers in the DM7838/
DM8838 transceiver are disabled by a NOR gate
control.
Each open-collector driver in the transceiver sinks
50 mA at 0.7V. It has the power to pull down
the double-terminated bus and drive 20 of the
low-current receivers.

TRI-STATE BUS
TR I-STATE logic (or TSL) outputs are active in
both the "I" and "0" state. This greatly improves
risetimes and allows many more driver/receiver
pairs to be connected to a bus since power is not
wasted in terminations. Switching delays can be
halved during certain data exchanges.
A disabled output switches into a third, highimpedance state. Only small leakage currents flow
in the output in this state, virtually disconnecting
the output from the bus. TSL outputs do not
"wire-O R" - the bus is operated by one set of
outputs at a time.
Figure 3 is a TSL bus line. Although there are no
terminations, reflections are less of a problem than
in a unified bus. The bus is tightly controlled
without terminations because the disabled driverS
actually clamp undershoots.

FIGURE 5. TRI-5TATE Line With Stub

Tests indicate the transceivers can drive bus lines
longer than 25 feet. They are guaranteed to source
10.4 mA at the minimum "one" level of 2.4V.
Small-signal source impedance is typically 50n
to '5.0V compared with 120n to 3.2V on the
unified bus. That' explains TSL's higher speed the active-pull-up output charges the line capaci·
tance much faster. If even greater source current
capability is needed, the DM7831/DM8831 and
DM7832/DM8832 are available. As quad singleended drivers they can source and sink at least
40 mA' (and have a source impedance of only
lln). They can drive lines with characteristic
impedance down to 40n.
When a peripheral equipped with a transceiver is
powered down or disabled, no current (apart from
microamps of leakage) will, flow in the input/
output while the data levels move between ground
and +5.0V. Other peripherals can still use the bus
without their signals being shunted or degraded.
The receivers are isolated like the unified bus
designs. (The DM7832/DM8832 has the same

degree of freedom. However, the DM7831/DM8831
has an output diode to Vcc to control transients
when used in its differential mode. It will clamp
the bus lines when powered-down, so it is not
recommended for use in a peripheral which might
be switched off in isolation from the rest of the
system).
In the TSL transceiver family, typical receiver
input characteristics are 17J.lA current, 400 mV
hysteresis, and 1.4V noise immunity. All types
are completely compatible with standard TTL.
Figure 4 shows a line with a stub (actually a
branch of equal length, to ease analysis). It is
terminated in the line's characteristic impedance
at all three ends.
Figure 5 shows an identical hook·up, this time
"terminated" only by a disabled TR I·STATE gate
at the receiving end and the stub end.

10·59

The result of driving the circuit of Figure 4 is
seen in Figure 6. The current pulled from the line
by the driver (top trace) was determined by the
effective impedance of the termination in parallel
with the 1200 line charged to 3.2V. When this
wavefront reached the fork, half the current was
drawn from each leg. So when the half-current
front arrives at the stub only half the voltage
pull-down results (Figure 6 lower trace).
A series of these timed halvings and quarterings
produces the bathtub effect shown. The duty
cycle distortion experienced by a receiver at the
stub termination is obvious. If we take off the
stub termination network, the situation gets no
better. Figure 7 shows it (time base and sensitivity
unchanged). The undershoot in the I~wer trace is
followed by an overshoot which reaches 1.0V above
ground: and the stub continues to ring (which
isn't surprising since its two ends have terminations

in 60n and infinity respectively). A receiver at
the end of the stub would have to be ignored
until the ringing had decayed, and its output
had become va lid.
Contrast this with Figure 8, demonstrating the
results of. the TRI-STATE driver of Figure 5. The
same rapid falling edge at the receiving end is
brought to a halt very sharply, and instead of
reflective overshoots, there is a shallow series of
level adjustments which never cross the maximum
zero level of O.4V above ground.
How is this achieved?
Figure 9 shows the schematic of the output' stage
of a TRI-STATE transceiver. Now if the output is
disabled, point A is held by the TRI-STATE control at VCEsat + VBE , or 1.0V at 25°C.

safe amount of time after the glitch seen in Figure

Often, a zero ground reference can't be establ ished
between remote subsystems. One can overwhelm
the ground difference with a high-amplitude, slngleended transmission. But a differential transmission
not referenced to ground is more efficient (Figure

levels, transmitted over a twisted-pair cable, and
received with a comparator sensitive enough to overcome signal degradations, yet rejecting common

The DM7820 and DM7830 designs were explained
in AN-22. Rather than repeat the information in
that note, the following sections will answer
questions frequently asked by users.
First, how does the new DM7820A differ from the
DM7820? They both have the same schematic.
One of the two receivers on the chip is shown in
Figure 18. However, the "A" version's fanout is
10 TTL or DTL loads rather than 2, the strobe
input is specified fully and is guaranteed to be
driven by saturated logic, and the speeds are
guaranteed.
Second, what establishes the driver current requirement? The receiver's non-inverting input is at the
center of a voltage divider between Vee and
ground. This sets the voltage into the terminal at
1/2 Vee, or 2.5V in a 5.0V system. The smallsignal input impedance is the parallel combination
of the two 5.0 kQ +167Q paths, or about 2.5 kQ.
When the input swings from high to ground, the
current transient is about 1.0 mAo A similar
analysis shows the driver must source about 1/2 mA
to bring the inverting input up to 2.4V.

DRIVING 7-SEGMENT GAS DISCHARGE DISPLAY
TUBES WITH NATIONAL SEMICONDUCTOR CIRCUITS

CQ

INTRODUCTION
Circuitry for driving high voltage cold cathode
gas discharge 7 ·segment displays, such as Sperry
Information Displays and Burroughs Panaplex II,
is greatly simplified by a complete new line
of monolithic Integrated cirCUits from National
Semiconductor. The new products also make
possible reduced cost of system Implementation.
They are: DM7880/DM8880 high voltage cathode
decoder/driver; DM8884A high voltage cathode
decoder/driver; DM8885 MOS to high voltage
cathode buffer; DM8889 low power cathode
driver; and DM8887 8·digit anode driver.
In addition to satisfying all the displays' parameter
requirements, including high output breakdown
voltage, the new circuits have capability of pro·
grammlng segment current, and provid ing constant
current sinking for the display segments. This
feature alleviates the problem of achieving uni·
formity of brightness with unregulated display
anode voltage. The National circuits can drive the
displays directly.
Sperry Information Displays and Burroughs Pan·
aplex II are used principally in calculators and
digital instruments. These 7·segment, multi·d,git
displays form characters by passing controlled
currents through the appropriate anode/segment
combinations. The cathode in any digit will glow
when a voltage greater than the ionization voltage
is applied between it (the cathode) and the anode
for that digit. In the multiplexed mode of opera·
tion, a digit position is selected by driving the
anode for that digit with a positive voltage pulse.
At the same time, the selected cathode segments
are driven with a negative current pulse. This
causes the potential between the anode and the
selected cathodes to exceed the ionization level,
causing a visible glow discharge.
Generally, these displays exhibit the following
characteristics: low "on" current per segmentfrom 200llA (in DC mode) to 1.2 mA (in multiplex
mode); high tube anode supply voltage-180V to
200V; and moderate Ionization voltage-170V.
Once the element fires, operating voltage drops
to approximately 150V and light output becomes
a direct function of current, which is controlled
by current limiting or current regulating cathode
circuits. Current regulation therefore IS most
desirable since brightness will then be constant
for large anode voltage changes. Tube anode to
cathode "off" voltage is approximately 100V;
and maximum "off" cathode I~akage is 31lA to
51lA.

Correspondingly, specifications for the cathode
driver must be complimentary, approximately as
follows: A high "off" output breakdown voltage
80V minimum; typical "on" output voltage of
5OV; maximum "on" output current of 1.5 mA
per segment; and maximum "off" leakage current
of 31lA to 51lA.
To allow operation without anode voltage regu·
latlon, the cathode driver must be able to sink a
constant current In each output, with the output

The DM7880/DM8880 decoder/driver provides for

drives 7 -segment digits of gas-filled displays. There
are two separate inputs and two additional outputs
for direct control of decimal POint and comma
cathodes. The inputs can be DC coupled to TTL
(Figure 3) or MaS outputs (Figure 4). or ACcoupled to TTL or MaS outputs (Figure 5) using
only a capacitor. This means the device is useful
in applications where level shifting is required. It
can be used In multiplexed operation, and is
available in an 18-pin molded DIP package.

DRIVING 7-SEGMENT LED DISPLAYS WITH
NATIONAL SEMICONDUCTOR CIRCUITS

INTRODUCTION
There are many different information display
technologies available today, including liquid
crystals, gas-discharge tubes, fluorescent tubes,
Incandescent lamps, and light emitting diodes
(LEDs)_ Each technology has its own particular
drive requirement_ This note will focus on 7segment LED display drive requirements and
demonstrate that National Semiconductor has
a full line of display drivers that meet the
requirements for most any 7-segment LED drive
appl ication_

Thus, Nationat,has circuits that will drive 7-segment
LEDs from either fully decoded circuits or from
non-decoded outputs.

CONFIGURATIONS AND CONSTRUCTION OF
7-SEGMENT LEDs

WHY ARE LED DRIVERS NEEDED?
The purpose of 7-segment LED drivers is to act
as an interface element between data input and'
the display. This interface is necessary when either
the input data format or circuitry current capabilIties do not allow direct connection between input
and display. To satisfy these needs, National's
7-segment LED drivers are divided into two basic
categories.

1. Internally decoded (BCD to 7-segment)
DM5446A/DM7446A
DM5447 A/DM7447 A
DM5448/DM7448
DM7856/DM8856
DM8857
DM 7858/DM 8858

LEDs are segregated into two groupings with
regard to construction, see Figure 1.
Common anode displays are constructed on a
common substrate which forms the anode of the
diodes, while each of the seven cathodes are
bonded out to separate pins. The second type,
common cathode, has the cathode fabricated on
a common substrate with the anodes bonded out
to individual pins_ Due to these radically different
'configurations, drive circuits are usually tailored
in their design for one or the other type, Tailoring
in this respect means either sinking current (active
low) or sourcing current (active high) when referenced to segment drive. I n addition, drive
requirements are quite variable because of LED
light intensity requirements as well as digit size

and efficiency. Thus the system designer needs a
degree of latitude not only with respect to the
type of display used but also the drive current
available.
7·segment LEDs can be purchased in either single
or multi-digit display packages. Single digit displays
have individual segment and common pins while
multi-digits have paralleled segment pins and
separate digit pins equal to the number of digits
in the package, see Figure 2.
Multi·digit displays, due to their configuration,
must be driven in a multiplex mode of drive, where
segment drivers are time shared by all the digits.
This is contrasted to the single digit displays which

10·78

may be driven in either the multiplex or the nonmultiplex (direct drive) mode. The ,nonmultiplex
mode uses separate segment drivers for each digit
of the display. Multiplex operation has a decided
cost saving advantage over nonmultiplex operation
especially when the number of digits being driven
is large.
MODES OF 7-SEGMENT LED DRIVE
In the multiplex mode of drive the LED digits
in a multi-digit format are driven by a single set
of segment drivers while each digit is selected by
its own digit driver. Figure 3 shows the circuitry
needed to implement a typical six digit multiplexed
display.

»

z
Each digit is selected individually by enabling its
digit driver whose control is determ ined by a
counter or equivalent circuitry operating at some
clock frequency. Strobed data, by way of the
counter and multiplex circuitry, is then displayed
on the selected digit by the single set of segment
drivers. If the strobe rate is high enough, from
about 250 to 1,000 .Hz depending on external
conditions, the display will appear flicker free to
the human eye. The BCD·to·7·segment decoder
converts BCD data to the desired 7·segment output
format.

In summary, LED driver requirements for multiplex or nonmultiplex drive operation require
either segment, digit or BCD to 7-segment drivers.
Analysis of the particular system needs with
regard to the number of digits and relative circuit
costs should be the determining factor for multiplex or nonmultiplex operation. Circuit requirements for multiplex operation will in general
require relatively high current capabilities.

In the multiplex mode each digit has a reduced
duty cycle and is operated at somewhat higher
than average or typical dc operating current levels.
The amount of current will be a function of the
number of digits, duty cycle, and the type
and efficiency of the display used. Since currents
are higher than average so also will be the LED
brightness due to the nearly linear brightness
versus current curve for most LEDs. The human
eye will detect the brightness peaks and through a
partially integrating and peak detecting action will
perceive a higher display brightness at some average
current level in the multiplex mode than the same
average current in the nonmultiplex (direct drive)
mode. The result is that a multiplexed display will
operate at a lower total power than the same
display operated in the nonmultiplex mode with
the same apparent brightness.

Table I lists the 7-segment LED drivers available
from National. Each circuits application is divided
into groupings with respect to common anode or
cathode, digit or segment, multiplex or nonmultiplex areas. Additionally, current capabilities are
also specified for each product.

In the nonmultiplex mode of 7·segment LED drive
each digit has its own set of segment drivers
thereby dropping the digit driver select require·
ment of multiplexed operation. In this case, the
common digit pin may be tied to the highest
potential if common anode or the lowest if
common cathode. It is evident that in a nonmultiplexed display the driver package count
would be high since each digit requires its own
set of segment and possibly decoder drivers.
If a large number of digits are used the segment
driver package count wou Id equal the number of
digits while in the multiplex mode this count
is equal to one. Granted, in the multiplex mode
additional control circuitry is required. Consideration of the relative cost of this circuitry in
comparison to the segment decoder driver circuitry
in the nonmultiplex mode results, in general, in
the fact that if the number of digits in the display
equals or is more than four, total package count
and/or cost is less in the multiplex mode of drive.

In most MOS circuits multiplex operation is ideal
since the counter, multiplexer, and BCD to 7segment decoders or equivalent circuitry can
usually be incorporated on the same chip along
with calculator, clock or other function. In this
case the only external interface components
required would be the digit and segment drivers
since MOS circuits are generally unable to sink
or source the higher current required for most
multiplex operations.

From the table it is evident that some of the
circuits may be used in dual roles - both multiplex
or nonmultiplex; common cathode or anode. In
general, what will determine whether one drivers
application is multiplex or nonmultiplex is that
drivers current capability. The direction of current
flow through the driver (source or sink) is the
determining factor in dual application with regard
to common anode or cathode.

This family of BCD to 7-segment decoder drivers
was designed for the most general possible display drive appl ications including display technologies other than LEDs. The difference between
the circuits is in their output stage configurations.
These differences wi II be discussed separately later.

The circuits convert the standard 4-bit BCD input
to the popular 7-segment output format. All
input BCD codes above 9 are decoded into unique
patterns that verify operation. The circuits are
TTL-DTL compatible and operate off of a single
5.0V supply.

Added features included in all circuits are a ripple
blanking input pin as well as a lamp test pin for
display turn on. In addition the blanking input/

DM5446A/DM7446A, DM5447 A/DM7447 A
These circuits feature active-low, open collector
high current outputs (Figure 4a). Each output is
capable of sinking up to 40 mA at a maximum
internal drop of OAV. This high current capability
makes these circuits particularly well suited for
driving the large MAN-lor equivalent type displays
directly. The circuits are also applicable, with or
without the use of external current limit resistors,
to driving lower current displays in the multiplex
mode of drive.
The DM5446A and DM7446A outputs are capable
of withstanding 30V at a maximum leakage of
250MA over temperature. The DM5447A and
DM7447 A have a 15V output capability at a
maximum leakage over temperature of 250MA.
This standoff voltage ability makes the circuits
applicable for direct drive to indicator lamp type
displays. Figure 5 shows a typical application of
the circuits with LEDs.

Refer to Table II for the operating temperature
range and package types for the DM5446A/
DM7446A and DM5447A/DM7447A.
DM5448/DM7448
The DM5448/DM7448 has active high passive
pull-up outputs (Figure 4b) with a TTL fanout of
4. The typical output source current is 2.0 mA at
an output voltage of 0.85V. Each output is
capable of sinking 604 mA with a maximum'
internal drop of OAV. Since the output current
level is low the circuit can be used to drive low
current common cathode displays operating in the
nonmultipiex mode.
The major application of the DM5448/DM7448
is to drive logic circuits, operate high-voltage
loads such as electroluminescent displays through
buffer transistors or SCR switches. or high-current

This series of three circuits was designed'to pro·

common cathode 7·segment LEOs operating in the
multiplex or nonmultiplex mode. The circuits,
discussed individually below, have output stages
with varying source current capability designed
for specific as well as general applications.
All circuits accept 4·bit BCD and decode this input
to the desired 7·segment output format for direct
drive to LEDs. In addition, the circu its feature a
lamp test pin for display turn·on check, ripple
blanking·input pin and blanking input/ripple
blanking output pin which may be used to
modulate display intensity.
The three circuits are TTL·DTL compatible and
provide full decoding of the 16 possible input
combinations. All parts operate off of a single

j:ach output has a fan·out of 4 and is capable of
sinking 6.4 mA with a maximum internal drop of
O.4V making the circuit suitable for use with logic
circuits. With the use of an external buffer tran·
sistor per output the circuit may be used to drive
high current common anode LED displays as well
as high voltage electroluminescent displays. Figure

DM8857. The output stages are exactly the same
as the DM8857 except that the internal current
limit resistor per output has been removed.
External current limit resistors must then be used.
This allows the circuit to be customized for a
particular common cathode multiplex or nonmultiplex application. Each output stage, through
its own external resistor, can be programmed to
some current from 50 mA down to 0 mAo Care
must be taken in not shorting the outputs to
ground because of the excessive current flow that
would result from the Darlington upper stage. See
Figure 9 for a typical application of the DM8858.

The applications of this circuit obviously are not
limited to just the MAN-4 type of display. Common
cathode displays with high dc current requirements or lower multiplex current levels may be
driven by this circuit with the use of an external
current limit resistor per segment. A typical application of the DM8857 is given in Figure 8.

INTRODUCTION

Digital systems generally require the transmission of
digital signals to and from other elements of the system.
The component wavelengths of the digital signals will
usually be shorter than the electrical length of the cable
used to connect the subsystems together and, therefore,
the cables should be treated as a transmissions line. In
addition, the digital signal is usually exposed to hostile
electrical noise source which will require more noise
immunity then required in the individual subsystems
environment.
The requirements for transmission line techniques and
noise immunity are recognized by the designers of subsystems and systems, but the solution used vary con·
siderably. Two widely used example methods of the
solution are shown in Figure 1. The two methods

which will induce noise on the system, as indicated in

The signals in adjacent wires inside a cable may induce

characteristics of the line that effect the quality, and will

The cables used to transmit digital signals external to a
subsystem and in route between the subsystem, are
exposed to external electromagnetic noise caused by

induced from relay circuits which have very large transient voltage swings compared to the digital signals in the
same cable. Another source of induced noise is current
in the common ground wire or wires in the cable.

DISTORTION
The objective is the transmission and recovery of digital
intelligence between subsystems, and to this end, the
characteristics of the data recovered must resemble the
data transmitted. In Figure 4 there is a difference in the
pulse width of the data and timing signal transmitted,
and the corresponding signal received. In addition there
is a further difference in the signal when the data is
"ANO"ed with the timing signal. The distortion of the
signal occurred in the transmission line and in the line
driver and receiver.

The rise time in a transmission line is not an exponential
function but' a complementary error function. The high
frequency components of the step input are attenuated
and delayed more than the low frequency components.
This attenuation is inversely proportional to the fre·
quency. Notice in Figure 6 particularly that the signal
takes much longer to reach its final dc value. This effect
is more significant for fast risetimes.
The Outy Cycle of the transmitted signal also causes
distortion. The effect is related to the signal rise time as
shown in Figure 7. The signal doesn't reach one logic
level before the signal changes to another level. If the
signal has a 112 (50%) Outy Cycle and the threshold of
the receiver is halfway between the logic levels, the distortion is small. But if the Outy Cycle is 1/8 as shown in
the second case the signal is considerably distorted. In
some cases, the signal may not reach the r~ceiver threshold at all.

A primary cause of distortion is the effeCt the transm is·
sion line has on the rise time of the transmitted data.
Figure 5 shows what happens to a voltage step from the
driver as it travels down the line. The rise time of the
signal increases as the signal travels down the line. This
effect will tend to affect the timing of the recovered
signal.

FIGURE 7. Signal Distortion Due to Duty Cycle

In the previous example, it was assumed that the
threshold of the receiver was halfway between the ONE
and ZERO logic levels. If the receiver threshold isn't
halfway the receiver will contribute to the distortion of
the recovered signal. As shown in Figure 8, the pulse
time is lengthened or shortened, depending on the
polarity of the signal at the receiver. This is due to the
offset of the receiver threshold.

FIGURE 9. Unbalanced Method

Transmission lines don't necessarily have to be perfectly
terminated at both ends, (as will be shown later) but the
termination used in the unbalanced method will cause
additional distortion. Figure 10 shows the signal on the
transmission line at the driver and at the receiver. In this
case the receiver was terminated in 120£2, but the char·
acteristic impedance of the line is much less. Notice that
the wave forms have significant steps due to the
incorrect termination of the line. The signal is subject to
misinterpretation by the line receiver during the period
of this signal transient because of the distortion caused
by Duty Cycle and attenuation. In addition, the noise
margin of the sighal is reduced.

The circuit used for a line receiver in the balanced
method is a differential amplifier. Figure 14 shows a noise
transient induced equally on line A and line B from line
C. Because the signals on line A and B are equal, the
signals are ignored by the differential line receiver.
Likewise for the same reason, the differential signals on
line A&B from the driver will not induce transients on
line C. Thus, the balanced method doesn't generate noise
and also isn't susceptible to noise. On the other hand
the unbalanced method is more sensitive to noise and
also generates more noise.

lines should alsQ be terminated for unbalanced signals.

of a balanced transmission line. This termination method
is primarily required for accurate impedance measure·

The unbalanced method circuit used in this application
note up to this point is the unbalanced circuit shown in
Figure 1. The termination of its transmission line was
greater than the characteristic impedance of the unbal·
anced line and the circuit had considerable threshold
offset. The measured performance of the unbalanced cir·
cuit wasn't comparable to the balanced method. There·
fore, for the following comparison of unbalanced and
balanced circuits, an improved termination shown in
Figure 17 will be used. This circuit terminates the line in
60n and minimized the receiver threshold offset.

FIGURE 14. Cross Talk of Signals

The characteristic impedance of the unbalanced trans·
mission line is less than the impedance of the balanced
transmission line. In the unbalanced method there is
more capacitance and less inductance than in the bal·
anced method. I n the balance method the Reactance to
adjacent wires is almost cancelled (see Figure 15). As a
result a transmission line may have a 60n unbalanced
impedance and a 90n balanced impedance. This means
that the unbalanced method, which is more susceptible
to I R drop, must use a smaller value termination, which
will further increase the I R drop in the line.

Figure 19 shows the reduction in Data Rate caused by

Duty Cycle. It can be observed that the Absolute Maxi·
mum Duty Rate of 118 Duty Cycle is less than 112 Duty
Cycle. The following performance curves will use 1/8
Duty Cycle since it is the worst case.
Absolute Maximum Duty Rate versus the Line
Termination Resistance for two different lengths of
cable is shown in Figure 20. It can be seen from the
figure that the termination doesn't have to be perfect in
~he case of balanced circuits. It is better to have a termi·
nation resistor to minimize the extra transient signal
reflecting between the ends of the line. The reason the
Data Rate increases with increased Termination Resist·
ance is that there is less I R drop in the cable.

the unbalanced method versus line length and versus the
number of line drivers corresponding to the test configuration delineated in Figure 23_ In the noise measurement set-up there was a ground return for each signal
wire_ If there is only one ground return in the cable the
performance is worse_ The graph shows that the effective
line length is drastically reduced as additional Near End

no measurable degradation of the circuits Data Rate or
distortion.
CONCLUSION
National has a full line of both Balanced and Unbalanced
l"ine Drivers and Receivers. Both circuit types work well
when used within their limitations. This application note
shows that the balanced method is perferable for long
lines in noisy electrical evironments. On the other hand
the unbalanced circuit works perfectly well with shorter
lines and reduced data rates. It should be kept in mind
that when you are spending $500,000 for a CPU and
$75,000 for peripherals, it pays to investigate the best
way to transmit data between them.

The minimum unit interval reflected the worse case

MIL-STO-883
Mil-Standard-883 is a Test Methods and Procedures
Document for Microelectronic Circuits. It was
derived from MIL-S-19500, MIL-STD-750, and
MIL-STD-202C for transistors and diodes at about
the time that National Semiconductor Corporation
was entering the military microelectronics market.
As a result, our standard quality control operations
are written around MI L-STO-883. The bonding
control, visual inspections, and post seal screening
requirements set forth by 883 (as well as added
control procedures beyond the requirements of
883) have been part of National's quality control
procedures almost from the start. Our Quality
Assurance Procedures Manual is available upon
request.

We offer a complete line of linear/883 (Class B)
products as standard, off-the-shelf items_ Special
Linear/883 data sheets have been prepared to
reflect this capability. They show process flow,
electrical parameters, end of test criteria, and test
circuits. We save you the problem of specifying test
and inspection procedures, and offer significant
cost savings by having an off-the-shelf, "to the
letter" 883 program. In addition, we will test any
of our integrated circuits to any class of MILSTD-883.
The detailed information concerning MI L-STD-883
screening is contained in National's specification
NSC10002_

MIL-M-38510
MIL-M-38510 specifies the general requirements
for supplying microcircuits. These are; product
assurance, which includes screening and quality
conformance inspection; design and construction;
marking; and workmanship. The screening and
quality conformance inspection are conducted in
accordance with MIL-STD-883.

The MIL-M-38510 specs for standard linear devices
require 100% DC testing at 25°C, _55°C and
+125°C. AC testing is performed at +25°C. The
electrical parameters specified are tighter than the
normal data sheet guaranteed limits. Additionally,
MIL-M-38510 requires device traceability, extensive documentation and closely matched maintenance.

SCREENING
All microcircuits delivered in accordance with MI LM-38510 must have been subjected to, and passed
all the screening tests detailed in Method 5004 of
MIL-STD-883 for the type of microcircuit and
product assurance level.
The device electrical and package requirements of
MIL-M-38510are detailed by a device specification
referred to as a slash sheet. Each slash sheet defines
the microcircuit electrical performance and mechanical requirements. Each device listed on a slash
sheet is referred to as a slash number and the group
of the microcircuits contained on a slash sheet is
defined as a family of devices. The device may be
Class B or C as defined by MIL-STD-883, Method
5004 and 5005. Three lead finishes are allowed
by the slash sheet, pot solder dip, bright tin plate,
and gold plate.

QUALITY CONFORMANCE
Quality conformance inspection is conducted in
accordance with the applicable requirements of
Group A, (electrical test), Group Band C, (environmental test) of Method 5005, M I L-STD·883. These
tests are conducted on a sample basis With GroupA
performed on each sublot, Group B on each lot,
and Group C as specified (usually every three
months).
To supply devices to MI L-M-38510, the IC manufacturer must quality the devices he plans to supply
to the detail specifications. Qualification consists
of notifying the qualifying activity of one's intent
to qualify to MIL-M-38510. After passing comprehensive audits of facilities and documentation
systems, the IC manufacturer will subject the
device to and demonstrate that they satisfy all of

11-1

MIL-M-38510 (con't)
the Group A, B, and C requirements of Method
5005 of MIL-STD-883 for the specified classes and
types of IC_ The qualification tests shall be monitored by the qualifying agency. Finally the IC
manufacturer shall prepare and submit qualification test data to the qualifying agency. Groups A,
B, and C inspections then shall be performed at
intervals no greater than three months.

performed on a sample of devices which are chosen
at random from a lot of devices that has satisfactorily completed the screening of Method 5004
must be performed on each device, Le. on a 100%
basis as opposed to qualification testing (Method
5005) which occurs on a random sample basis.
In summary, the entire purpose of MIL-M-38510
and MIL-STD-883 is to provide the military,
through its contractors with standard devices.

The purpose of qualification testing is to assure
that the device and lot quality conform to certain
standard limits. In effect, lot qualification tests
tend to ensure that once a particular device type
is demonstrated to be acceptable, it's production,
including materials, processing, and testing will
continue to be acceptable. These limit$ are specified in MIL-STD-883 in terms of LTPD's (Lot
Tolerance Percent Defective) for the various qualification test sub-groups. Qualification testing is
