INTRODUCTION

The increase in complexity and diversity of Linear Integrated Circuits over
the last few years has necessitated a change in the format of the Fairchild
Linear Data Books. In this data book, Fairchild is pleased to present important technical information on one of the industries broadest and most advanced family of Linear Interface, Comparator and Data Conversion circuits.
Other Fairchild Linear data books will cover Operational Amplifiers, Consumer and Regulator devices.
Fairchild continues to be a pioneer in Linear Interface and Data Conversion
products. Today Fairchild's state-of-the-art technology is bringing forth devices like the 9643; MOS/CCD driver, 75S20 series of Schottky core memory
sense amplifiers, 9634/6/7/8 series of RS422/423 compatible line circuits,
f.LA9708; micro-processor based 8-bit AID subsystem, and the CMOS processed f.LA9706; micro-processor compatible 8 channel, 6-bit D/A converter.
You'll find complete specifications on Fairchild's MOS/CCD memory interface, data transmission, peripheral driver, memory sense amplifier, display
interface, data conversion, comparator and special functions. Also included
is advanced information on some of Fairchild's Interface circuits to be introduced shortly.
To expedite the designer's search for the right devices to meet various system requirements, several helpful aids are provided - selection guides by
function, an LlC cross reference identifying competitive devices with their
Fairchild direct replacements or nearest equivalents and the numerical indexes will let you locate specific type numbers quickly. For the Hi Rei customer, Fairchild's Hi Rei processing and Matrix VI are given in a separate
section.

Quality, Reliability and Hi Rei Processing ................................................ 3-3

QUALITY, RELIABILITY AND HI REL PROCESSING
Introduction
There are three basic ingredients in the manufacture of reliable Linear Circuits. First, the device must be
designed with the user's applications and reliability requirements in mind. Secondly, the device must be
manufactured with the optimum technology for the application. Thirdly, controls must be established to
assure maintenance of the quality/reliability levels established in the design of the device. Consideration
is given to the reliability influence of each part of the manufacturing and testing cycle with constant feedback from internal reliability monitoring; customer feedback on the results is a vital factor. The Fairchild
reliability concept can be presented as constant feedback system which begins and ends with the customer (Figure 3-1).
Areas of Consideration
Device Applications and Reliability
The reliability cycle begins with the customer. His device application, environment for its usage and endproduct reliability requirements are major factors in establishing the quality/reliability levels. The customer is the final judge.

Device Design
Inherent component reliability is a function of the product/process design. New Fairchild designs as well as
modifications or extensions of existing designs with known performance and reliability characteristics are
rigorously evaluated. Three different factors in the manufacture of an IC significantly affect its reliability.

The Silicon Chip- Fairchild's design-technology capability utilizes epitaxial layer to achieve the
desired electrical parameter characteristics. The surface influences long-term gain and voltage/leakage stability. The metallization determines mechanical integrity and current distribution.
Chip Assembly - The process and materials used to assemble the chip and package must preserve
the inherent reliability of the chip and be inherently reliable to withstand thermal, mechanical and
electrical stresses.
The Package - The package must effectively transfer heat from the chip to the outside world and
protect the chip during handling and use.
Incoming Quality Control (IQC)
All purchased materials for Fairchild Linear circuits are controlled through central specification control,
product engineering, and reliability and quality assurance (R&OA) located in Mountain View. Materials
are purchased and inspected per control documents using three IOC methods.

Direct visual and mechanical inspection
Functional testi ng
Composition analysis utilizing chemical and x-ray techniques from both internal and external sources.

In addition to centralized IOC, each manufacturing facility has a local, fully equipped IOC department.
These facilities concentrate on cleanliness, plating quality and functionality. A computer file is made on
each vendor's performance and quarterly reports are generated and analyzed.

Wafer Manufacture
Wafers used to fabricate Fairchild Linear Circuits are made at Fairchild. This includes crystal pulling,
slicing, polishing and epitaxial layer growth. Fairchild designs rely on accurate control of thickness and
resistivity. All operations have laminar-flow clean-air hoods directly over the work areas. Wafer
fabrication is essentially a series of masking and furnace cycles in which geometries are defined and
impurities (dopants) introduced to form emitter, base and resistor regions. Daily controls are maintained
on furnace temperatures to within ±1°C. Resistivities (ps) of diffused layers are recorded on every run.
Each masking step defines a new portion of the device geometry. A post develop inspection is performed
to assure that each wafer has been properly exposed and chemically developed before final etching.
When the masking and etching procedures are completed, a final inspection assures that the geometry is
properly aligned, etched and cleaned. Following each production masking step, a sample inspection is
performed by quality control inspectors to verify correct process implementation.
After masking and diffusion, the metallization process completes wafer manufacture. Fairchild uses
electron-beam evaporation techniques to deposit gold and aluminum. DepOSits are controlled through
utilization of automated process sequencing,which includes an automatic thickness controller. Every
run is gated through a first optical ("I st opU inspection before it leaves the wafer fabrication area.
Cleanliness, mask alignment, metal adherence (front and back) and general workmanship are inspected.

Wafer Testing
Before the wafers are scribed and broken into dice for assembly onto headers or shipment toa customer
as probed dice, they are electrically sorted. Each wafer is automatically probed with multiple tests to
duplicate or correlate the dice to the final product test requirements. Rejected dice are ink marked and
later scrapped. A final quality control gate is performed before the probed wafers can be forwarded to
assembly.
Device Assembly
After the wafers are scribed and broken, a second optical (2nd opU QC inspection is performed. The dice
are inspected for wafer fabrication (handling) damage, as well as for defects which may cause assembly
problems or result in latent reliability problems.
Monitors are performed on both assembly equipment and operators. Machines are shut down if defect
control limits are exceeded and suspect material is rejected and 100% screened. Key items inspected are
die orientation, voids under die, proper bond formation, wirepull strength and cleanliness.
A third optical (3rd opU gate is performed prior to final device sealing. If rejected, the lot is 100% screened
by production and resubmitted to QC. Accepted lots are sent to the final seal operation, where the
packages are monitored for weld strength and hermeticity (except plastic packages).
Device Testing
Before shipment, all devices are 100% production tested to the following minimum inspection levels.

0.25% AQL

Customers with special testing requirements are accommodated through an internal specification
system. All internal test speCifications formatted frbm customer documents are signed off by QA before
they can be issued to the test area.
Device Application
The total reliability effort is completed full-cycle with the customer. Operation in the customer application is the final consideration in device reliability. How each device is handled during system assembly by
the customer, heat-sunk (mounted) and cooled during operation, and the amount of overload stresses
(due to the system malfunction or misuse) greatly impacts the device reliability. Thus, the customer's
specification requirements, the manufacturer's device design, manufacture, test, the actual circuit into
which the device is inserted and the equipment containing that circuit in the field all affect the device and
reliability.
Failure Analysis
Failure analYSis results performed by customers and by Fairchild on returned devices provide one of the
most important inputs for consideration in Fairchild's total linear reliability concept. Failures generated
by line monitors, life tests and field applications are analyzed to provide corrective action in terms of
product design, assembly and testing methods. A scanning electron microscope (SEM) and an Auger
electron microscope for chemical analysis are available for inspection of materials.

HI REL PROCESSING - MIL-M-38510/MIL STD-883
A unique "company", within Fairchild Linear, is totally dedicated to the processing of high reliability
products and to serving the special needs of the HI REL community. It consists of marketing, engineering, production control, manufacturing and quality assurance. Fairchild's HI REL processing facilities
are among the most modern and sophisticated in the semiconductor industry. Screening procedures are
set up to conform to the most recent version of MIL-STD-883, in conjunction with MIL-M-38510, which
establishes standardized requirements for design, material, performance, control and documentation
needed to achieve prescribed levels of device quality and reliability.
HI REL Unique II Program
Fairchild's Unique II program fills a longstanding need for a definite and comprehensive program
covering HI REL semiconductor products ... a program offering users a selection among multi-level
screening flows and reliability requirements ... a program providing clear and precise definitions on all
areas of contractual performance ... a program designed to reduce the high costs and delivery delays
normally associated with HI REL. The objectives and benefits of the Unique II program for integrated
circuits are these:
•
•
•
•

MATRIX VI- COMMERCIAL AND INDUSTRIAL RELIABILITY PROGRAM
Commercial and industrial users increasingly demand optimized quality and reliability for the semiconductor integrated circuits purchased for their systems. Specific factors - increased integrated circuit
usage per board, high costs for receiving inspection, pc board and systems repair, and the frequently
immeasurable cost associated with field failures- require the user to attain high quality and reliability
coupled with total cost. Matrix VI is designed to meet these user requirements.
Fairchild's Matrix VI Program offers a broad spectrum of screens and high technology/high volume
integrated circuit products to meet the user's quality and reliability requirements typically associated
with the commercial and industrial marketplace. There are two screening options for each package type,
each with a separate degree of reliability and cost level. To simplify a cost-effective analysis, reliability
factors have been assigned to each screening level. (See following pagesJ
It is the goal of Matrix VI to aChieve the highest possible reliability consistent with the user's needs and to
avoid "over-buying". Cost-effective reliability is the essence of Matrix VI, the most comprehensive
program of its kind now offered to the industrial/commercial marketplace.

Burn~ln has the same relative effectiveness for plastic molded devices as for ceramic/hermetic packaged devices. Assuming a controlled (air conditioned and constant power) field application/environment, the reliability factor would be approximately 9x. But should the field application be in a less controlled and power on/off application, the reliability would be approximately 7.5X.

NOTES:
1. This rating applies for ± 15 V supplies. The positive input voltage limit is 30 V above the negative supply. The negative input voltage limit is
equal to the negative supply voltage or 30 V below the positive supply, whichever is less.
2. Rating applies to ambient temperatures up to 70 o e. Above 700 e ambient derate linearly at 6.3 mwle for metal can; 8.3 mwle for mini

DIP.
3. The offset voltage, offset current and bias current specifications apply for any supply voltage from a single 5 V supply up to ± 15 V supplies.
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.
5. The response time specified (see definitions) is for a 100 mV input step with 5 mV overdrive.
6. For input voltages greater than 15 V above the negative supply the bias and offset currents will increase ~ see typical performance curves.

This rating applies for ±15 V supplies. The positive input voltage limit is 30 V above the negative supply. The negative input voltage limit is
equal to the negative supply voltage or 30 V below the positive supply, whichever is less.
Rating applies to ambient temperatures up to 70°C. Above 70°C ambient derate linearly at 6.3 mW/oC for metal can; 8.3 mW/C for
mini DIP.
The offset voltage, offset current and bias current specifications apply for any supply voltage from a single 5 V supply up to ± 15 V supplies.
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 aCCOl..,lnt the worst case effects of voltage gain and input impedance.
The response time specified (see definitions) is for a 100 mV input step with 5 mV overdrive.

LOW-POWER, LOW OFFSET VOLTAGE QUAD COMPARATORS
FAIRCHILD LINEAR INTEGRATED CIRCUITS
GENERAL DESCRIPTION - The p.A 139 series consists of four independent precision
voltage comparators designed specifically to operate from a single power supply.
Operation from split power supplies is also possible and the low power supply current
drain is independent of the supply voltage range. Darlington connected PNP input
stage allows the input common-mode voltage to include ground.

NOTES:
1. For operating at high temperatures, the /lA339/ .uA339A, ,...A2901 ,uA3302 must be derated based on a 125 0 C maximum junction temperature and a thermal
resistance of 125°C/W which applies for the device soldered in a printed circuit board, operating in a still air ambient. The ,uA139 and /-tA139A~
must be derated based on a 1500 C maximum junction temperature. The low bias dissipation and the "ON-OFF' characteristic of the outputs keeps thechip dissipation very small \PD -::; 100 mWI, provided the output transistors are allowed to saturate.
2. Short circuits from the output to V+ can cause excessive heating and eventual destruction. The maximum output current is approximately 20 mA independent of the magnitude of Vi.
3. This input current will only exist when the voltage at any of the input leads is driven negative. It is due to the collector-base junction of the input PNP
transistors becoming forward biased and thereby acting as input diode clamps. In addition tiode action, there is also lateral NPN parasitic transistor
action on the Ie chip. This transistor action can cause the output voltages of the comparators to go to the V+ voltage level lor to ground for a large overdrive I for the time duration that an input is driven negative. This is not destructive and normal output states will reestablish when the Input voltage, which
negative, again returns to a value greater than -0.3 V.
4. These specifications apply for V+ = 5.0 V and -55°e::; TA::; +125°C, unless otherwise stated. With the ~A239/~A239A,aJl temperature specifications
are limited to _25° C::; TA::; +85° e, the ,uA339/,uA339A temperature specifications are limited to 0° e::; TA::; +70°C, and the ,uA2901, ,uA3302 temperature
range is _40° e ::; T A ::; +85° C.
5. The direction of the input 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 lines.
6. The input common-mode voltage or either input signal voltage should not be allowed to go negative by more than 0.3 V. The upper end of the commonmode voltalge range is V+ -1.5 V, but either or both inputs can go to +30 V without damage.
7. The response time specified is for a 100 mV input step with 5 mV overdrive. For larger overdrive signals 300 ns can be obtained; see typical performance
characteristics section.
8. Positive excursions of input voltage may exceed the power supply level. As long as the other voltage remains within the common-mode range, comparator will provide a proper output state. The low input voltage state must not be less than -0.3 V or 0.3 V below the magnitude of the negative power
supply, if used.
9. At output switch point, Va =: 1.4 V, Rs = on with V+ from 5 V; and over the full input common-mode range 10 V to V+ -1.5 VI.
10. For input signals that exceed VcC,-only the overdriven comparator is affected. With a 5 V supply, VIN should be limited to 25 V max, and a limiting resistor
should be used on all inputs that might exceed the positive supply.

APPLICATION HINTS
The fJ.A 139 series are high-gain, wide-bandwidth devices which, like most compaFators, 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 (1.0 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.

~I pi~ of any unused comparators should be grOund:0
The bias network of the fJ.A 139 series establishes a drain current which is independent of the magnitude of the power supply voltage over the range of from 2 V to 30 V.

•

It is usually unnecessary to use a bypass capacitor across the power supply line.
G e differential input voltage may be larger than V+ without damaging the devi;;"rotection
should be provided to prevent the input voltages from going negative more than -ffi(at 25° C).
An input clamp diode can be used as shown in the applications section.
The output of the fJ.A139 series is the uncommitted collector of a grounded-emitter npn output
transistor. Many collectors can be tied together to provide an output ~Ring 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 fJ.A139 package. The output can also be used as asimple
SPSTswitch 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 f3 of this
device. When th-e maximum current limit is reached (approximately 16 mAl, 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 60 n saturation resistance 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.

DUAL HIGH-SPEED DIFFERENTIAL COMPARATOR
FAIRCHILD LINEAR INTEGRATED CIRCUIT

GENERAL DESCRIPTION -

The IlA711 is a Dual, Differential Voltage Comparator intended
primarily for core~memory sense amplifier applications. The device features high accuracy, fast response

times, large input voltage range, low powe~ consumption and compatibility with practically all

integrated logic forms. When used as a sense amplifier, the threshold voltage can be adjusted over a
wide range, almost independent of the integrated circuit characteristics. Independent strobing of each
comparator channel is provided, and pulse stretching on the output is easily accomplished. Other
applications of the dual comparator include a window discriminator in pulse height detectors and a
double-ended limit detector for automatic Go/No-Go test equipment. The ~A711, which is similar to
the ,uA710 differential comparator, is constructed using the Fairchild Planar* epitaxial process.

PRECISION VOLTAGE COMPARATOR
FAI RCH ILD LINEAR INTEGRATED CIRCU IT

GENERAL DESCRIPTION - The IlA 734 is a Precision Voltage Comparator constructed on a single
silicon chip using the Fairchild Planar* epitaxial proces~. It is specifically designed for high accuracy
level sensing and measuring applications. The ,uA734 is extremely useful for analog·to-digital
converters with twelve bit accuracies and one mega-bit conversion rates. Maximum reso1ution is

obtained by high gain, low input offset current, and low input offset voltage. Its superior temperature
stability can be improved by offset nulling which further reduces offset voltage drift. Balanced or

HIGH SPEED DIFFERENTIAL COMPARATOR
FAIRCHILD LINEAR INTEGRATED CIRCUIT

GENERAL DESCRIPTION - The pA760 is a Differential Voltage Comparator offering considerable
speed improvement over the ,uA710 family and operation from symmetric supplies of from ±4.5 V to
±6.5 V. The MA76D can be used in high speed analog to digital conversion systems and as a zero
crossil19 detector in disc fi Ie and tape amplifiers. The .uA760 output features balanced rise and fall times

for minimum skew and close matching between the complementary outputs. The outputs are TTL
compatible with a minimum sink capability of two gate loads.

FAIRCHILD LINEAR INTEGRATED CIRCUIT

GENERAL DESCRIPTION - The pA0802, pA0802H, pA0802A, pA08028, and
pA0802C are monolithic 8-bit multiplying Digital-to-Analog Converters constructed
using the Fairchild Planar" epitaxial process. It is designed for use where the output
current is a linear product of an 8-bit digital word and an analog input voltage. The
pA0802 is specified for the military temperature range (-55°C to +125°C) and the
pA0802H, pA0802A, pA08028 and pA0802C are specified for O°C to 70°C operation.

CIRCUIT DESCRIPTION

The /LA7151 consists of five circuit blocks as shown in Figure 1. The blocks may be connected in a
variety of ways to construct voltage-to-frequency converters (VFC), frequency-to-voltage cQnverters
(FVC), or other circuit functions. The circuit blocks are:
1. A differential input comparator featuring very high gain, low offsets, and a common mode range
which includes ground.
2. A one-shot multivibrator with the time constant set by an external RC (T = 1.1 RC) connected to
the RC terminal, triggered by the output of the comparator being high.
3. A precision switched current source that is turned on to the value of IREF when the one-shot is
on and goes to zero when the one-shot is off. The current IREF is set by an external Rs , connected from the scale factor terminal-to-ground and is equal to the reference voltage divided by
Rs and is optimized when set to 138 /LA.
4. An open collector output that provides a buffered output from tre one-shot.
5. An operational amplifier whose common mode range includes ground and has offset null capability. The op amp has high gain, low offset voltage, low input currents, good PSRR and CMRR,
and low drift.
PRINCIPLE OF OPERATION
Voltage to Frequency Conversion (VFC)

As a voltage to frequency converter the /LA7151/4151 can be connected in several configurations
depending on the input voltage, required accuracy, and response time. In all the applications we will
see that the input voltage is converted to a current and the circuit will turn the switched current
source on at the rate necessary so that the average current from the current source is equal to the
input current. As the input voltage (and current) increases, the current source must turn on more
often, and the output frequency increases.
SELECTING COMPONENTS FOR THE VFC

Voltage-to-frequency converters can be used for full scale voltages of 100 mV or greater and full
scale frequencies of 1 Hz to 100 kHz. Input voltages in excess of V cc+ can be accommodated with
appropriate resistor dividers to attenuate the voltages. The following components selection
guidelines should be used.
1. Rs should be approximately 14 kfl to optimize the system performance versus temperature. Rs
is normally a 12 kfl fixed resistor and a 5 kfl pot to be used to adjust the full scale output
frequency. Small variations in Rs have minimal effect on system temperature performance.
IREF = VREF/Rs = 1.95 V/Rs
2. Ro Co sets the one-shot pulse width, To = 1.1 Ro Co. This pulse width must be shorter than the
minimum period of the maximum frequency ie, set it equal to .75 (1/fo). Therefore, Ro Co = .68
(1/fo). Values of Ro should be between 6.8 kfl and 680.kfl and Co should be from .001 /LFto 1 /LF.
3. Rs should be as low as possible for the highest accuracy, (this reduces the effect of current
source ROUT) but must be large enough to insure that the current source output is greater than
VIN max/Rs· Therefore, choose Rs such that Rs - 1.33 VIN max/l o.
4. C s for Figure 2 must be chosen to trade-off between accuracy and response time. Larger values of C s give greater system accuracy but response time is limited by the Rs Ds time constant. A good choice for Ds is 1O-2 /fo.
5. C1 for Figures 3 and 4 can be selected depending on the output frequency. The smaller C1 is
the faster the system response wil be. C1 must be large enough to limit the amplifier swing. The
op amp will swing a voltage set by loTofC1 , so if the comparator is biased at 2/3 V cc + this
constrains C1 > 3 loTo/2 Vcc+. A nominal value of C1 = 5 x 1O-5 /fo meets this requirement.
COMPARISON OF VOLTAGE TO FREQUENCY CIRCUITS

Table I shows a comparison of the three basic circuits set-up for a 0 to 10 V input range and a full
scale output of 10kHz.
FREQUENCY TO VOLTAGE CONVERSION

The /LA7151/4151 can be connected as frequency-to-voltage converter (FVC). This circuit basically
works by putting out a current pulse per cycle of input frequency and intergrating the current pulses
across an output resistor to give an output voltage which is proportional to the average value of 10
(10TofIN)·

MULTI-CHANNEL, 12-BIT ACCURATE,
JLP COMPATIBLE, D/A CONVERTERS
FAIRCHILD LINEAR INTEGRATED CIRCUITS
GENERAL DESCRIPTION - The }.LA9706 and }.LA9706A are digital-to-analog-converters which allow a microprocessor system to interface and control analog systems.
The }.LA9706 is programmed by 9-bit words, accepted in a serial format, while the
}.LA9706A accepts 9-bit words in parallel 3-bit groups. Both the }.LA9706 and }.LA9706A
provide conversions on all channels simultaneously and continuously as long as the
oscillator signal is present. Digital-to-analog conversion is accomplished using a
pulse-width ratio technique for directly controlling the duty cycle of the output pulse
streams. Each channel, when appropriately filtered, supplies 6-bit resolution, or 64
discrete analog levels. By properly summing two outputs, the resolution may be controlled up to 12 bits, or 4096 discrete levels. The }.LA9706 provides 8-channel operation,
whereas the }.LA9706A provides 7-channel operation. Each channel outpulrna'jntains
12-bit, or ±.01% full-scale, accuracy.

FUNCTIONAL DESCRIPTION The functional blocks of the IlA9706 and p.A9706A are defined by the pulse-width ratio conversion
scheme that they employ. In addition, other requirements-which include microprocessor compatibility, multi-channel operation, and simultaneous conversion of all channels add to the basic
structure. The p.A9706 consists of seven functional blocks: a 6-bit binary counter, a pulse
distributor called a priority encoder, 6 x 8 RAM, 1-of-8 channel address decoder, 6-to-1 channeldata multiplexer, 9-bit input shift register, and a set of eight output buffers.
Tile pulse-width-ratio conversion scheme divides the conversion cycle into binary-weighted
time intervals and associates each time interval with a bit position in the 6-bit control word. The
control word residing in RAM is then addressed, bit by bit, each bit addressed for the associated
time interval. The value of each bit, "1" or "0", controls the output, HIGH or LOW, during this time
interval (see Figure 1). In this manner, an output pulse stream is generated with a duty cycle defined by the control word. When the pulse stream is filtered, a dc value is extracted that is proportional to the duty cycle of the pulse stream and, hence, proportional to the control word.
The 6-bit counter generates the fundamental time intervals for the system and may be driven
by any open-collector TTL or CMOS logic that produces a square-wave signal with a frequency
in the range of 50 kHz to 2 MHz. The time intervals (binary-weighted pulse widths) generated by the
counter are decoded by the priority encoder which serves two functions. First, it ensures that each
of the six time intervals (control pulses) is used once during the conversion cycle. Second, it distributes the control pulses to both the channel-data multiplexer and to the column-address inputs
of the 6 x 8 RAM.

TIME

Fig. 1 Output Cycle Example

The channel-data multiplexer is enabled during the write mode so that the 6-bit control word
may be written. The 6 x 8 RAM provides the storage capability required forthe converterto operate
independently of the microprocessor, once the control information has been transferred. Since
the control information is stored in RAM, simultaneous conversions continue on all eight channels,
unaided by the microprocessor unless changes are required. This is accomplished by addressing
a single bit in each of the control words and reading the results out in parallel during each time
interval in the conversion cycle. The total cy~le time, which is the sum of the six binary-weighted
time intervals plus a unit interval (64 clock periods), requires 128 oscillator periods, since the basic
oscillator frequency is divided by a factor of two before driving the counter. Conversions may be
completed in as little as 64 p'S when operating at a 2 MHz clock rate. The control words read from
the RAM are directed to the output buffers, six of which have 1 kfl and two have 50 n output impedances. In general, these buffers should drive load impedances larger than the output impedance to reduce the errors caused by the finite output impedance.
Each output is capable of providing 64 discrete output levels representing 6-bit resolution. Since
each output pulse stream is accurate to 12 bits, it is possible to sum two outputs and expand the
resolution to 12 bits, providing 4096 discrete output levels. This may be easily accomplished by
weighting one of the outputs by a factor of 1/64 before summing.
Loading data is a simple procedure that does not affect the conversion cycle. For the p.A9706, the
6-bit control word (channel data) and the 3-bit channel address are serially transferred to the 9-bit
shift register on the HIGH-to-LOW transitions of the data clock (Figure 2). The data clock has a
maximum frequency of 125 kHz with a minimum HIGH and LOW time of 4 p.s. Once the nine bits
of data have been transferred into the shift register, the data clock must remain static until the write
operation is completed to prevent the data from being shifted out of the register. The write mode
may be selected after a minimum setup time of 1 P.s and is enabled bya HIGH-going W/R control
pulse. This sets an internal latch that enables the channel-address decoder, which decodes the
3-bit binary channel address, therefore effecting the transfer of the 6-bit control word from the
input register to RAM via the channel-data multiplexer at the beginning of the next conversion
cycle. The W/R pulse has two restrictions: first, it must be equal to or greater than 4 p'S in duration;
second, it must be less than 128/f05c . This latter restriction is necessary to eliminate the possibility
of multiple loads occurring from a single W/R pulse that could lead to incorrect control-word transfers under certain conditions.
The p.A9706A is basically the same as the p.A9706 except for two differences: input structure
and pin limitation. The p.A9706A has three 3-bit shift registers, used for temporary storage of the
3-bit channel address and 6-bit control word. This structure is bus oriented and provides for
parallel3-bit transfers between the microprocessor and the converter (Figure 3). Also, before any
transfers can take place, a 3-bit ID code must be accepted. The ID code is provided in parallel over
the ID clock and DBa, DBl and DB2 inputs. After the nine bits of data are transferred to the shift
registers, the operation of the p.A9706A is identical to the p.A9706. The p.A9706A provides 7-channel
operation as opposed to the 8-channel operation of the p.A9706.

FUNCTIONAL DESCRIPTION
This Analog to Digital Converter is a single-slope 8-bit, 6-channel AID converter that provides all of
the necessary analog functions for a microprocessor-based data/control system. The device uses
the processor system to provide the necessary addressing, timing and counting functions and
includes a 1 of 8 decoder, 8-channel analog multiplexer, sample and hold, precision current
reference, ramp integrator and comparator on a single monolithic Chip.

For applications that require auto-zero or auto-calibration, (See Figures 2-5) line select address 0,
0, and 1, 1,1 may be used in conjunction with the arithmetic capability of the microprocessor to
provide ground and scaling factors. Address 0, 0,
internally connects the input of the ramp
generator to ground and may be used for zero offset correction in subsequent conversions.
Address 1,1,1 internally connects the input of the ramp generator, to the voltage reference, VREF,
and may be used for scale factor correction in subsequent conversions. For the following, refer to
the Functional Block Diagram.

°

°

Six separate external analog voltage inputs may come into terminals 1,-16 and the specific analog
input to be converted is selected via address terminals Ao-A2. The analog input voltage level is
transferred to the external ramp capacitor connected to pin 4 when the input to the ramp start
terminal (pin 3) is at a logic (See Figure 1). The time to charge the capaCitor is the acquisition time

which is a function of the output impedance of an amplifier internal to the AID and the value of the
capacitor. After charging the external capacitor the ramp start terminal is switched to a logic 1
which introduces a high impedance between the analog input voltage and the external capacitor.
The capacitor begins to discharge at a controlled rate. The controlled rate of discharge (ramp) is
established by the external reference voltage, the external reference resistor, the value of the
external capacitor and the internal leakage of the AID. Connected to the capacitor terminal is a
comparator internal to the AID with its output going to the ramp stop terminal (pin 7), The
comparator output is a logical one when the capacitor is charged and switches to a logic 0 when the
capacitor is in a discharged state. The ramp time is the time from when ramp start goes high (logic
"1") to when ramp stop goes low (logic "0"), The microprocessor must be programmed todetermine
this conversion time. The ideal (no undesirable internal source impedances, leakage paths, errors
on levels where comparator switches or delay time) conversion time is calculated as follows.

SYSTEM HINTS:

Several alternatives exist from a hardware/software standpoint in microprocessor based systems
using the I'A9708.
1. The ramp time measurement may be implemented in software using a register increment,
followed by a branch back depending on the status of the ramp stop.
2. Alternately, the ramp stop may be tied into the interrupt structure in systems containing a
programmable binary timer. This scheme has the following advantages:
A. The CPU is not committed during the ramp time interval.
B. It requires only 4 bits of an I/O port for control signals.
3. The auto-zero/auto-full-scale (see Figures 2-5) should use double precision, rounded (as
opposed to truncated) arithmatics. Several points are worth noting:
A. The subtractions are single op code instructions.
B. The full scale correction uses a multiply by 256 and can be accomplished by a shift left 8 bits
(usually one instruction) or placing (N-Nz) in the MSB register and setting the LSB register to
zero, for the double precision divide.
C. The divisor (NF.S. - Nz) MSB's register will always be zero.
These schemes have the following advantages:
A. No access to the data buss or address buss is required, by the A/D system.
B. 4 I/O bits completely support the AID system.
C. Since auto full scale/auto zero are implemented in software and long term drift (aging) effects
are eliminated.
D. Software overhead is minimal (typically 30 bytes)'
E. Where ratiometric operation is permissible, the 4 external components may be ±5% tolerance, including the power supply.

DUAL DIFFERENTIAL LINE DRIVERS
FAIRCHILD LINEAR INTEGRATED CIRCUITS

GENERAL DESCRIPTION - The 9612 Dual Differential Line Driver is designed specifically to drive

single ended or differential, back matched or terminated transmission lines. The outputs are similar to
totem pole TTL outputs, with active pull-up and pull-down, for use in simplex or simplex distribution

bus systems. The devices feature a short circuit protected active pull-up. The inputs and outputs have
clamp diodes to minimize the effect of line transients. The active pull-up output offers low output
impedance allowing back matching or parallel termination of the line. The 9612E and 9612A are

specified to drive 50

DUAL DIFFERENTIAL LINE DRIVER
FAIRCHILD LINEAR INTEGRATED CIRCUIT

GENERAL DESCRIPTION - The 9614 is a TTL compatible Dual Differential Line Driver. It is
designed to drive transmission lines either differentially or single-ended, back-matched or terminated.
The outputs are similar to TTL, with the active pull up and the pull down split and brought out to
adjacent pins. This allows multiplex operation (Wired-OR) at the driving site in either the single-ended
mode via the uncommitted collector, or in the differential mode by use of the active pull ups on one
side and the uncommitted collectors on the other (See Fig. 5). The active pull up is short circuit
protected and offers a low output impedance to allow back-matching. The two pairs of outputs are
complementary providing NAND and AND functions of the inputs, adding greater flexibility.
The input and output levels are TTL compatible with clamp diodes provided at both input and
output to handle line transients.

9616
TRIPLE EIA RS-232-C/MIL-STD-188C LINE DRIVER
FAIRCHILD LINEAR INTEGRATED CIRCUIT

GENERAL DESCRIPTION - The 9616 is a Triple Line Driver which meets the electrical interface specifications of EIA RS-232-C and CCITT V.24 and/or MIL-STD-188C
(by the appropriate device selection). Each driver converts TTL/DTL logic levels to EIA/
CCITT and/or MIL-STD-188C logic levels for transmission between data term ina I
equipment and data communications equipment. The output slew rate is internally
limited and can be lowered by an external capacitor; all output currents are short-circuit
limited. The outputs are protected against RS-232-C fault conditions. A logic HIGH on
the inhibit terminal interrupts signal transfer and forces the output to a VOL (EIA/CCITT
MARK) state.

9634
DUAL 3-STATE DIFFERENTIAL LINE DRIVER
FAIRCHILD LINEAR INTEGRATED CIRCUIT

GENERAL DESCRIPTION - The 9634 Dual3 - state Line Driver is designed specifically
to meet the EIA standard RS -422. It provides unipolar differential drive to twisted - pair
or parallel-wire transmission lines. The outputs are similar to totem - pole TIL circuits
but with the active pull- up and pull-down circuits split and brought out to adjacent pins.
The active pull- up circuit is short circuit protected. In addition to the normal lowimpedance HIGH and LOW states, the 9634 outputs provide a high-impedance OFF
state, which is controlled by the output STROBE function. When the output control
(STROBE) is HIGH, the associated outputs are high - impedance states neither driving
nor loading the line permitting flexibility in party-line or bus applications. The 9634 is
specified to drive 500 terminated transmission lines at high speeds. The inputs are
TIL and CMOS compatible.

DUAL PROGRAMMABLE SLEW RATE LINE DRIVER
(EIA RS-423 DRIVER)
FAIRCHILD LINEAR INTEGRATED CIRCUIT

GENERAL DESCRIPTION - The 9636A is a TTL/CMOS compatible, dual, singleended, line driver which has been specifically designed to satisfy the requirements of
EIA Standard RS-423.
The 9636A suitable for use in digital data transmission systems where signal wave
shaping is desired. The output slew rates are jOintly controlled by a single external
resistor connected between the wave shaping control (WS) pin and ground. This
eliminates any need for external filtering of the output signals. Output voltage levels
and slew rates are independent of power supply variations. Current limiting is provided
in both output states. The 9636A is designed for nominal power supplies of ±12 V.

DUAL HIGH SPEED DIFFERENTIAL LINE DRIVER
(EIA-RS-422)
FAIRCHILD LINEAR INTEGRATED CIRCUIT

GENERAL DESCRIPTION - The 9638 is a Schottky, TTL-compatible Dual Channel
Differential Line Driver, designed specifically to meet the EIA-RS-422 specifications. It
is designed to provide unipolar differential drive to twisted-pair or parallel-wire transmission lines. The inputs are TTL compatible. The outputs are similar to totem-pole
TTL outputs, with active pull-up and pull-down. The device features a short-circuit
protected active pull-up with low output impedance and is specified to drive 50 n
transmission lines at high speed. The mini DIP provides high package density.

DUAL LINE RECEIVERS
FAIRCHILD LINEAR INTEGRATED CIRCUITS

GENERAL DESCRIPTION - The 55/75107A/B and 55/75108A/B are high speed, two·channel
Line Receivers with common voltage supply and ground terminals. They are designed to detect input
signals of 25mV (or greated amplitude and convert the polarity of the signal into appropriate TTL
compatible output logic levels. They feature high input impedance and low input currents which
induce very little loading on the transmission line making these devices ideal for use in party line

systems. The receiver input common mode voltage range is ±3V but can be increased to .*; 15V by
the use of input attenuatars. Separate or common strobes are available. The 55175107A/B circuit
features an active pull·up (totem pole outputl. The

55/75108A/B

circuit features an open collector

output configuration that permits wired·QR connections. The receivers are designed to be used with
the 55109175109 and 55110175110 line drivers. The

55175107A/B

The input protection diodes are useful in certain party·line systems which may have multiple
VCC+ power supplies and, in which case, may be operated with some of the VCC+ supplies
turned off. In such a system, if a supply is turned off and allowed to go to ground, the equivalent
input circuit connected to that supply would be as follows:

This would be a problem in specific systems which might possibly have the transmission lines
biased to some potential greater than 1.4 V. Since this is not a widespread application problem,
both the A and B versions will be available. The ratings and characteristic specifications of
the B versions are the same as those of the A versions. The B versions will be supplied upon

RECEIVER

The
55/75107A/B dual line circuits are designed specifically for use in high speed data transmission systems that utilize balanced,
terminated transmission lines such as twisted~pair lines. The system operates in the balanced mode, so that noise induced on one line is
also induced on the other. The noise appears common-mode at the receiver input terminals where it is rejected. The ground connection

between the line driver and receiver is not part of the signal circuit so that system performance is not affected by circulating ground currents.
The unique driver output circuit allows terminated transmission lines to be driven at normal line impedances. High speed system operation is
ensured since line reflections are virtually eliminated when terminated lines are used. Cross·talk is minimized by low signal amplitudes and low
line impedances.
The typical data delay in a system is approximately (30+ 1.3L) ns, where L is the distance in feet separating the driver and receiver. This
delay includes one gate delay in both the driver and receiver.
Data is impressed on the balanced-line system by unbalancing the line voltages with the driver output current. The driven line is selected by
appropriate driver·input logic levels. The voltage difference is approximately:
VDIFF ~ 1/2 IOUT(on) • RT

High series line resistance will cause degradation of the signal. The receivers, however, will detect signals as low as 25 mV (or less). For normal
line resistances, data may be recovered from lines of several thousand feet in length.
Line-termination resistors (RT) are required only at the extreme ends of the line. For short lines, termination resistors at the receiver only may
prove adequate. The signal amplitude will then be approximately:
VOIFF ~ IOUT(on) • RT

The strobe feature of the receivers and the inhibit feature of the drivers allow the 55/75107A/B dual line circuits to be used in data-bus or
party-line systems. In these applications, several drivers and receivers may share a common transmission line. An enabled driver transmits data
to all enabled receivers on the line while other drivers and receivers are disabled. Data is thus time-multiplexed on the transmission line. The
55/75107A/B device specifications allow widely varying thermal and electrical environments at the various driver and receiver locations.
The data-bus system offers maximum performance at minimum cost.

The

55175107A/B

dual line circuits may also be used in unbalanced or single·line systems. Although these systems do not offer the same

performance as balanced systems for long lines, they are adequate for very short lines where environment noise is not severe.
The receiver threshold level is established by applying a de reference voltage to one receiver input terminal. The signal from the transmission
line is applied to the remaining input. The reference voltage should be optimized so that signal swing is symmetrical about it for maximum
noise margin. The reference voltage should be in the range of -3.0 V to +3.0 V. It can be provided by a voltage supply or by a voltage divider
from an available supply voltage.

PRECAUTIONS IN THE USE OF 55175107A/B AND 55/75108A/B DUAL LINE RECEIVERS

The following precaution should be observed when using or testing

55/75107 AlB

line circuits:

When only one receiver in a package )s being used, at least one of the differential inputs of the unused receiver should be terminated at some
voltage between -3.0 V and +3.0 V, preferably at ground. Failure to do so will cause improper operation of the unit being used because of
common bias circuitry for the current sources of the two receivers.

The 55/75107A/B

line receivers feature a
common·mode input voltage range of ±3.0 V. This satisfies the require-

ments for all but the noisiest system applications. For these severe 'noise
environments, the common-mode range can be extended by the use of
external input attenuators. Common-mode input voltages can in this
way be reduced to ±3.0 V at the receiver input terminals. Differential
data signals will be reduced proportionately. Input sensitivity, input

the requirements of the standard interface between data terminal equipment and data communication
equipment as defined by EIA Standard RS-232C. Other applications are for relatively sllOrt, single·line,
point-ta-point data transmission and for level translators. Operation is normally from a single 5 V
supply; however, a built-in option allows operation from a 12 V supply without the use of additional
components. The output is compatible with most TTL and DTL circuits when either supply

voltage is used.
In normal operation, the threshold control terminals are connected to the VCC1 terminal, pin 15,
even jf power is being supplied via the alternate VCC2 terminal, pin 16. This provides a wide hysteresis
loop which is the difference between the positive~going and negative-going threshold voltages. In this
mode of operation, if the input voltage goes to zero, the output voltage will remain LOW or HIGH as
determined by the previous input.
For fail~safe operation, the threshold~control terminals are open. This reduces the hysteresis loop by
causing the negative-going threshold voltage to be above zero. The positive~going threshold voltage
remains above zero as it is unaffected by the disposition of the threshold terminals. In the fail-safe
mode, if the input voltage goes to zero or an open~circuit condition, the output will go HIGH
regardless of the previous input condition.

TRIPLE EIA RS-232-C LINE RECEIVER
FAIRCHILD LINEAR INTEGRATED CIRCUIT

FOR NEW DESIGNS, THE ILA1489/1489A, 75154 OR THE 9637A ARE RECOMMENDED.

GENERAL DESCRIPTION - The 9617 is a monolithic Triple Line Receiver constructed using the

P

Fairchild Planar* process. It is designed to meet the terminator electrical requirements of EIA RS~232-C

and CCITT V.24. It receives line signals produced by the 9616, an EIA/CCITT driver, and converts
them to TTL compatible logic levels. The inputs have a resistance between 3 kn and 7 kf2 and can
withstand ±25 V. Each receiver can operate in either hysteresis or non-hysteresis (slicing) modes, and
each receiver provides fail-safe operation as defined by Section 2.5 of RS-232-C. Noise immunity may

be increased by connecting a capacitor between the response control pin and ground.
For the hysteresis mode connect the RESP pin to the HYST pin, for the slicing mode leave these
pins open.

DUAL LINE RECEIVER
FAIRCHILD LINEAR INTEGRATED CIRCUIT
GENERAL DESCRIPTION - The 9622 is a Dual Line Receiver designed to discriminate a worst case
logic swing of 2.0V from a ±10V common mode noise signal or ground shift. A 1.5V threshold is
built into the differential amplifier to offer a TTL compatible threshold voltage and maximum noise

immunity.

CONNECTION DIAGRAMS
14-PIN DIP
(TOP VIEW)
PACKAGE OUTLINES 6A 9A
p
PACKAGE CODES D

The offset is obtained by use of current sources and matched resistors and varies only

±5% (75 mY) over the military and industrial temperature ranges.

The 9622 allows the choice of output states with the inputs open without affecting circuit performance by use of S3 (Note 1). A 130[2 terminating resistor is provided at the input of each line

receiver. An enable is also provided for eachlline receiver. The output is TTL compatible. The
output HIGH level can be increased to +12V by tying it to a positive supply through a resistor. The
output circuits allow wired~OR operation.

DUAL EIA RS-232-C/MIL-STD-188C LINE RECEIVER
FAIRCHILD LINEAR INTEGRATED CIRCUIT

GENERAL DESCRIPTION - The 9627 is a Dual Line Receiver which meets the electrical interface
specifications of EIA RS·232~C and MIL-STO-188C. The input circuitry accomodates ±25V input
signals and the differential inputs allow user selection of either inverting or non-inverting logic for

the receiver operation. The 9627 provides both a selectable hysteresis range and selectable receiver
input resistance. When pin 1 is tied to VEE, the switching points are at +2.6V and -2~6V, thus
meeting RS-232-C requirements. When pin 1 is open·, the switching points are at +0.45V and -0.45V,
thus satisfying the requirements 10 MIL-STD-188C LOW level interface. Connecting the RIN pin to
the (-) input yields an input impedance in the range of 3kl1 to 7kl1 and satisfies RS-232-C
requirements; leaving R IN unconnected, the input resistance will be greater than 6kn to satisfy
MI L-STD-188C.
The output circuitry is TTL/DTL comDatible <'Inri will RllnI/\/ "rnllp,.'tn . . _rl ..... t:":i'"'~" ":':' 2~~~:-:~~ !~::;
wire-AND function. A TTL/DTL strobe is also provided for each receiver. The ErA failsafe mode of
operation is shown in the application section of this data sheet.

QUAD 3-STATE BUS TRANSCEIVERS
FAIRCHILD LINEAR INTEGRATED CIRCUIT

GENERAL DESCRIPTION -I'A8T26A and I'A8T28 are quad 3-state bus transceivers
featuring MPU or MOS compatibility. Both parts feature high-impedance PNP inputs
and high-speed operation made possible by the use of Schottky transistor technology.
. These devices are useful as bus extenders in systems employing the F6800, F3870 or
other comparable MPU families. Maximum input current of 200 I'A at the device input
pins assures proper operation despite limited drive capability of the MPU chip.
The I'A8T26A128 are identical to the NE8T26A/28 or the MC8T26A/28.

QUAD GENERAL PURPOSE BUS TRANSCEIVERS
FAIRCHILD LINEAR INTEGRATED CIRCUITS

GENERAL DESCRIPTION - The 9640, 9641 and 9642 are High-Speed Quad Bus
Transceivers. Each driver output, which IS capable of sinking 100 mA at 0.8 V, is connected Internally to the high-speed bus receiver in addition to being connected to the
package pin. The receiver has a Schottky TTL output capable of driving ten Schottky TIL
unit loads. The bus output is capable of driving lines having 1000 impedance.
The line can be terminated at both ends and stl,ll give considerable noise margin at the
receiver. The receiver typical switching point IS 2.0 V.

RECEIVER
CUTD

The 9640, 9641, and 9642 feature advanced Schottky processing to minimize propagation delay. The device package also has two ground pins to improve ground current
handling and allow close decoupling between Vee and ground at the package. Both
GND1 and GND2 should be tied to the ground bus external to the device package.
The 9640 and 9641 are pin for pin replacements of the AM26S 10 and AM26S 11 respectively.
The 9642 is the same device as the 9640 With hysteresis. The hysteresis characteristic
of the 9642 receiver is chosen so that the receiver switches to a HIGH logic level when
the receiver input is at a HIGH logic level and moves to 1.4 V typically, and switches to
a LOW logic level when the receiver Input IS at a LOW logic level and moves to 2.0 V
typically. This hysteresis characteristic allows for increased noise immunity in low speed
appl ications.

DUAL PERI PHERAL DRIVERS
FAIRCHILD LINEAR INTEGRATED CIRCUITS

GENERAL DESCRIPTION - The 55175450A, 55175451A, 55175452A, 55/75453A and 55/75454A are Dual High Speed General Purpose Interface
Drivers that convert TTL and DTL logic levels to high current drive capability. The 55450A and 75450A feature two TTL NAND gates and two
uncommitted transistors. The 55/75451A, 55/75452A, 55/75453A and 55175454A feature two standard series 74 TTL gates in AND, NAND, OR and
NOR configurations respectively, driving the base of two high voltage, high current, uncommitted collector output transistors.
The 55175450A series offers flexibility in designing high speed logic buffers, power drivers, lamp drivers, line drivers, MOS drivers, clock drivers and
memory drivers.

NOTES:

1. Voltage values are with respect to network ground terminal unless otherwise specified.
2. This is the voltage between two emitters of a multiple-emitter input transistor.

3. This value applies when the base-emitter resistance (RS E) is equal to or less than 500 n.
4. This is the maximum voltage which should be applied to any output when it is in the off state.
5. Soth halves of these dual circuits may conduct rated current simultaneously.
6. For the 55450A and 75450A only, the substrate (Pin 8), must always be at the most negative device voltage for proper operation.
7. Above 60°C ambient temperature, derate linearly at 8.3 mW;oC for Hermetic DIP and Molded DIP. For the Molded Mini DIP and Ceramic Mini

DIP, derate at 6.7 mwtC above 30°C.

DUAL HIGH SPEED PERIPHERAL DRIVERS
FAIRCHILD LINEAR INTEGRATED CIRCUITS

GENERAL DESCRIPTION - The 55/75450B, 55/75451 B, 55/75452B, 55/75453B and 55/75454B are Dual High Speed General Purpose Interface
Drivers that convert TTL and DTL logic levels to high current drive capability. The 55450B and 75450B feature two TTL NAND gates and two
uncommitted transistors. The 55/75451 B, 55/75452B, 55/75453B and 55/75454B feature two standard series 74 TTL gates in AND, NAND, OR and
NOR configurations respectively, driving the base of two high voltage, high current, uncommitted collector output transistors.

The 55/754508 series offers flexibility in designing high speed logic buffers, power drivers, lamp drivers, line drivers, MOS drivers, clock drivers and

memory drivers.

NOTES:
1. Voltage values are with respect to network ground terminal unless otherwise specified.
2. This is the voltage between two emitters of a mu Itiple-emitter input transistor.
3. This value applies when the base-emitter resistance (RBE) is equal to or less than 500 n.
4. This is the maximum voltage which should be applied to any output when it is in the off state.
5. Both halves of these dual circuits may conduct rated current simultaneously.
6. For the 55450B and 75450B only, the substrate (Pin 8), must always be at the most negative device vo~tage for proper operation.

7. Above 60°C ambient temperature, derate linearly at B.3 mWtC for Hermetic DIP and Molded DIP. For the Molded Mini DIP and Hermetic Mini
DIP, derate at 6.7 mwtC above 30°C.

DUAL HIGH VOLTAGE HIGH CURRENT PERIPHERAL DRIVERS
FAIRCHILD LINEAR INTEGRATED CIRCUITS

GENERAL DESCRIPTION - The 55/75460 Peripheral Driver Series converts TTL and DTL logic levels to HIGH voltage, HIGH current levels. The
55/75460 Series is directly interchangeable with the 55/75450 Series and affords higher breakdown at the expense of speed.The 55/75460 Series features
two 54/74 TTL input gates and two HIGH voltage HIGH current npn uncommitted transistors.
The 55/75461, 55/75462, 55/75463 and 55/75464 feature two standard 54/74 TTL input gates in AND, NAND, OR and NOR configurations, respec·

tively. The logic gates are internally connected

NOTES:
1. Voltage values are with respect to network ground terminal unless otherwise specified.
2. This is the voltage between two emitters of a multiple-emitter input transistor.
3. This value applies when the base-emitter resistance (RBE) is equal to or less than 500
4. This is the maximum voltage which should be applied to any output when it is in the off state.
5. Both halves of these dual curcuits may conduct rated current simultaneously.
6. For the 55460 and 75460 only, the substrate (Pin 8), must always be at the most negative device voltage for proper operation.
7. Above 70°C ambient temperature, derate linearly at 8.3 mW/oC for hermetic DIP.
For plastic Mini DIP and hermetic Mini DIP derate above 30°C at 6.7 mW/C.

DUAL HIGH VOLTAGE HIGH CURRENT PERIPHERAL DRIVERS
FAIRCHILD LINEAR INTEGRATED CIRCUITS

GENERAL DESCRIPTION - The 55/75471 series are dual very high voltage interface peripheral drivers with medium switching speeds. These devices
are pin-far-pin replacements of the (55/75451A-55/75454A), (55/75461-55/75464) and the (OS3611-0S3614) peripheral drivers.
The 55/75471 peripheral driver series converts TTL and OTL logic levels to high voltage, high current levels.
The 55/75471,55/75472,55/75473 and 55/75474 feature two standard TTL input gates in AND, NAND, OR and NOR configurations respectively.

The logic gates are internally connected to the bases of the npn transistors.
The 55/75471 series offers flexibility in designing very high voltage logic buffers, power drivers, lamp drivers, line drivers and relay drivers.

9665-9666-9667-9668
HIGH VOLTAGE, HIGH CURRENT DARLINGTON DRIVERS
FAIRCHILD LINEAR INTEGRATED CIRCUITS

GENERAL DESCRIPTION - The 9665, 9666, 9667 and 9668 are comprised of seven
high voltage, high current npn Darlington transistor pairs. All units feature common
emitter, open collector outputs. To maximize their effectiveness, these units contain
suppression diodes for inductive loads and appropriate emitter-base resistors for leakage.

16-PIN DIP
(TOP VIEW)
PACKAGE OUTLINE 68, 98
. PACKAGE CODE 0, P

The 9665 is a general purpose array which may be used with DTL, TTL, PMOS, CMOS,
etc. Input current limiting is done by connecting an appropriate discrete resistor to each
input.
The 9666 version does away with the need for any external discrete resistors, since each
unit has a resistor and a Zener diode in series with the input. The 9666 was specifically
designed for direct interface from PMOS logic (operating at supply voltages from 14 to
25 V) to solenoids or relays.
The 9667 has a series base resistor to each Darlington pair, thus allowing operation
directly with TIL or CMOS operating at supply voltages of 5 V.

The 9668 has an appropriate input resistor to allow direct operation from CMOS or
PMOS outputs operating from supply voltages of 6 to 15 V.
ORDER INFORMATION

9665, 9666, 9667 and 9668 offer solutions to a great many interface needs, including
solenoids, relays, lamps, small motors and LEOs. Applications requiring sink currents
beyond the capability of a single output may be accommodated by paralleling the outputs.

9624-9625
DUAL TTL, MOS INTERFACE ELEMENT
FAIRCHILD LINEAR INTEGRATED CIRCUIT

GENERAL DESCRIPTION - The 9624 is a Duar2-lnput TTL Compatible Interface Gate specifically
designed to drive MOS. The output swing is adjustable and will allow it to be used as a data driver,
clock driver or discrete MOS driver. It has an active output for driving medium capacitive loads.
The 9625 is a dual MOS to TTL level converter. It is designed to convert standard negative MOS logic
levels to TTL levels. The 9625 features a high input impedance which allows preservation of the driving
MOS logic level.
NOTE: The TTL and MOS devices manufactured by Fairchild Semiconductor are considered as positive
TRUE logic (the more positive voltage level is assigned the binary state of "'" or TRUE). Following
MI L-STD-806B logic symbol specifications, the 9624 is represented as a NAND gate and the 9625 as a
non-inverting buffer. This convention (of assuming MOS as a positive TRUE logic) has not been uniformly accepted by the industry; therefore, it is necessary to note that with negative TRUE MOS logic
(the more negative voltage level is assigned the binary state "'" or TRUE), the 9624 acts as an AND
gate and the 9625 as an inverter.

DUAL TTL TO MOS/CCD DRIVER
FAIRCHILD LINEAR INTEGRATED CIRCUITS

GENERAL DESCRIPTION - The 9643 and 9644 are Dual Positive-Logic "AND" and
"NAND" TTL-to- MOS Drivers respectively. The 9643 DC/PC is a functional replacement
of the SN75322 with one important exception: the two external PNP transistors are no
longer needed for operation. The 9643 DC/PC is also a functional replacement for the
75363 with the important exception that the V CC3 supply is not needed. The 9644 is a
logical inversion of the 9643 and is a functional replacement for the 75361. The pin
connections normally used for the external PNP transistors are purposely not internally
connected to the 9643 DC/PC.

Both devices have separate driver address inputs with common strobe. Both devices
accept standard TTL and DTL input signals and provide high-current and high-voltage output levels suitable for driving MOS/CCD memories. The 9643 may be used to
drive the chip-enable clock of the TMS4030 MOS RAM. The 9644 is suitable for
driving both clock and address inputs for the TMS4062 and 1103 RAM. The 9643 and
9644 operate from the TTL 5 V supply and the MOS supply.
The 9643 and 9644 are available in a-pin DIPs for increased board efficiency.

NOTES:
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.

2. These specifications apply fori(V+1 - (V-) = 10 Vt020 V, CL = 1000 pF, overthetemperature range of -55' C to +125' Clor the 9646DM and 0' Cto +70' Clor
the 9646PC.
3. All currents into device pins shown as positive, out of device pins are negative, all voltages referenced to ground unless otherwise noted. All values shown
as max or min on absolute value basis,

4. All typical values for the TA = 25' C.
5, Rise and fall time are given for MOS logic levels; i.e., rise time is transition from logic "0" to logic "1" which is voltage fall.

Fig. 3 SIMPLIFIED SCHEMATIC DIAGRAM

APPLICATIONS INFORMATION
OPERATION OF THE 9646/0026

The simplified schematic diagram of 9646/0026, shown in Figure 3 is useful in explaining the
operation of the device. Figure 3 illustrates that as the input voltage level goes high, diode D1
provides an 0.7 V "dead zone" thus ensuring that 02 is turned "on" and 04 is turned "off" before 07
is turned "on". This prevents undesirable "current spiking" from the power supply, which would
occur if 07 and 04 were allowed to be "on" simultaneously for an instant of time. Diode D2
prevents "zenering" of 04 and provides an initial discharge path for the output capacitive load by
way of 02.
As the input voltage level goes low, the stored charge in 02 is used advantageously to keep 02 "on"
and 04 "off" until 07 is "off". Again undesirable "current spiking" is prevented. Due to the external
capacitor, the input side of Gin goes negative with respect to VEE causing 09 to conduct
momentarily thus assuring rapid turn "off" of 07.
The complete circuit (equivalent circuit on front page) basically creates Darlington devices of
transistors 07,04 and 02 as shown in the simplified circuit of Figure 3. Note that when the input
goes negative with respect to VEE, diodes D7 through D10 turn "on" assuring faster turn "off" of
transistors 01, 02, 06 and 07. Resistor R6 insures that the output will charge to within one VSE
voltage drop of the Vee supply.
SYSTEM CONSIDERATIONS
Overshoot

In most system applications the output waveform of the 9646/0026 will "overshoot" to some degree,
However, "overshoot" can be eliminated or reduced by placing a damping resistor in series with the
output. The amount of resistance required is given by: Rs = 2.,ff]CL where L is the inductance of
Jhe line and GL is the load capacitance. In most cases a series of damping resistor in the range of 10to-50n will be sufficient. The damping resistor also affects the transition times of the outputs. The
speed reduction is given by the formula:
tTHL

~

trLH = 2.2 Rs GL (As is the dampi ng resistor>.

Crosstalk

The 9646/0026 is sensitive to crosstalk when the output voltage level is high (Va ~ Vee>' With the
output in the high voltage level state, 03 and 04 are essentially turned "off". Therefore, negativegoing crosstalk will pull the output down until 04 turns "on" sufficiently to pull the output back

8-20

FAIRCHILD. 9646/0026
towards Vee. This problem can be minimized by placing a "bleeding" resistor from the output to
ground. The "bleeding" resistor should be of sufficient size so that 04 conducts only a few
milliamperes. Thus, when noise is coupled, 04 is already "on" and the line is quickly clamped by
04. Also note that in the equivalent circuit 06 clamps the output one diode-voltage drop above Vee
for positive-going crosstalk.
Power Supply Decoupling
The decoupling of Vee and VEE is essential in most systems. Sufficient capacitive decoupling is
required to supply the peak surge currents during switching. At least a 0.1",F to 1.0 ",F low inductive
capacitor should be placed as close to each driver package as the layout will permit.
Input Driving
For those applications requiring split power supplies (VEE < GNO) ac coupling should be employed.
Selection of the input capacitor size is determined by the desired output pulse width. Maximum
performance is attained when the voltage at the input of the 9646/0026 discharges to just above the
device's threshold voltage (about 1.5 V). Performance curve shows optimum values for Gin versus the
desired output pulse width. The value for Gin may be roughly predicted by:
Gin = (2 x 10- 3 ) (PWo)·

For an output pulse width of 500 ns, the optimum value for Gin is:

If single supply operation is required (VEE = GNO), then dc coupling as illustrated in Figure 4 can be
employed. For maximum switching performance, a speed-up capacitor should be employed with
dc coupling. Performance curves show typical switching characteristics for various values of input resistance and capacitance.

DUAL SCHOTTKY CORE MEMORY SENSE AMPLIFIERS
FAIRCHILD LINEAR INTEGRATED CIRCUITS

GENERAL DESCRIPTION - Th.e 55/75820 series of 8chottky sense amplifiers are designed for use with
high-speed core memory systems, where a guaranteed narrow threshold uncertainty of ±2.5 mV is guaranteed.
A unique 8chottky circuit design provides inherent stability of the very accurate input threshold levels over a
wide range of power supply voltage levels and temperature ranges.
These sense amplifiers detect bipolar millivolt-level differential input signals from the memory and provide the
interface circuitry between the memory and the logic section.
The Fairchild 75820 and 75824 do not require an external capacitor (C ext) to stabilize the pre-amplifier section
of the sense amplifier. No degradation of performance will result if a 100 pF capacitor is connected from pin 1
to ground.
The 55/75820 circuit may be used to perform the functions of a flip-flop or register which responds to the sense
and strobe input conditions.
The 55/75824 is intended to be used in systems where independent dual channel sensing with separate outputs are required. 55/758234 is similar to the 55/75824, but have inverted outputs.

NOTES: 3. The differeotial-inputthreshold voltage (VT) is defined as the d-c differential·input voltage (V IO) required to force the output of the sense amplifier to the logic
gate threshold voltage level.
4. Common-mode input firing voltage is the minimum common"mode vottage that will exceed the dynamic range of the input at the specified conditions and
cause the logic output to switch. The specified common-mode input Signal is applied with a strobe-enable pulse present.

5520/7520 SERIES
CORE MEMORY SENSE AMPLIFIERS
FAIRCHILD LINEAR INTEGRATED CIRCU ITS
GENERAL DESCRIPTION - The 5520/7520 Series Dual Memory Sense Amplifiers are designed for use
in high speed core memory systems. These sense amplifiers detect the mV memory signals and transform
them into logic levels compatible with TTL and DTL circuits. Independent strobes for each channel provide the capability for performing time discrimination, resulting in the detection of the input signal when
the signal to noise ratio is at maximum. A common reference amplifier simultaneously sets the threshold of
each sense amplifier, and the r.eference amplifier and sense amplifier are compensated to reduce the effect
of power supply voltage or temperature variation. All gate inputs are compatible with TTL and DTL
circu its.

NOTES:
3. The differential input threshold voltage (VT) is defined as the dc differential input voltage (VI D) required to force the output of the sense
amplifier to the logic gate threshold voltage level.
4. Common mode input firing voltage is the minimum common mode voltage that will exceed the dynamic range of the input at the specified
conditions and cause the logic output to switch. The specified common mode input signal is applied with a strobe enable pulse present.

MEMORY DRIVER
FAIRCHILD LINEAR INTEGRATED CIRCUITS

GENERAL DESCRIPTION-The 55325 and 75325 are Memory Drivers fat use in magnetic memo
ories constructed on a silicon chip using the Fairchild Planar* process. The device contains four
600 rnA switches, two source switches and two sink switches that can be selected by the appropriate
logic input and appropriate strobe. The device has adequate base drive to source currents up to 375 rnA
with VCC2 of 15 V or 600 rnA with VCC2 voltage of 24 V. In applications requiring drive to source
currents greater than 375 rnA, an external resistor may be used to regulate the source base current to
within ±5% and reduce the power dissipation to allow higher source currents at higher ambient
temperatures.

55326-75326-55327-75327
MEMORY DRIVERS
FAIRCHILD LINEAR INTEGRATED CIRCUITS

GENERAL DESCRIPTION - The 55326. 55327. 75326 and 75327 are monolithic
integrated circuit quad memory drivers. These devices accept standard TTL decoder
input signals and provide high-current and high-voltage output levels suitable for driv:
ing magnetic memory elements. Output transistor selection is determined by using one
of the four address inputs and the common timing strobe.
The 55326 and 75326 memory drivers can sink up to 600 mA and operate from a
single 5 V supply.
The 55327 and 75327 memory switches can source or sink up to 600 mA and operate
from two supplies; one of 5.0 V and the other from 4.5 V to 24 V. The 55327 and 75327
can function as either sink drivers or source drivers since the voltages at the output transistor terminals are capable of swinging between VCC2 and ground.

TRANSISTOR AND DIODE ARRAYS
FAIRCHILD LINEAR INTEGRATED CIRCUITS
GENERAL DESCRIPTION - Fairchild Transistor and Diode Arrays consist of general purpose integrated circuit devices constructed
on a single substrate, using the Fairchild Planar' epitaxial process. These arrays are arranged to offer maximum flexibility in circuit
design for applications from dc to 120 MHz. Excellent transistor and diode matching and temperature tracking allow circuit
techniques unavailable when using discrete devices. Multiple devices in one package permit a greater packing density and cost saving
than with individually packaged transistors.

TEMPERATURE-CONTROLLED DIFFERENTIAL PAIR
FAIRCHILD LINEAR INTEGRATED CIRCUIT

GENERAL DESCRIPTION - The /lA 726 is a Monolithic Transistor Pair in a high thermal-resistance
package, held at a constant temperature by active temperature regulator circuitry. The transistor pair

CONNECTION DIAGRAM

(TOP VIEW)
PACKAGE OUTLINE 5U
PACKAGE CODE H

displays the excellent matching, close thermal coupling and fast thermal response inherent in
monolithic construction. The high gain and low standby dissipation of the regulator circuit permits

tight temperature control over a wide range of ambient temperatures. It is intended for use as an
input stage in very~low-drift de amplifiers, replacing complex chopper-,stabilized amplifiers. It is also
useful as the nonlinear element in logarithmic amplifiers and multipliers where the highly predictable

exponential relation between emitter-base voltage and collector current is employed. The device is
constructed on a single silicon chip using the Fairchild Planar* process.

SINGLE TIMING CIRCUIT
FAIRCHILD LINEAR INTEGRATED CIRCUIT

GENERAL DESCRIPTION - The IlA555 Timing Circuit is a very stable controller for producing
accurate time delays or oscillations. In the time delay mode, the delay time is precisely controlled by
one external resistor and one capacitor; in the oscillator mode, the frequency and duty cycle are both
accurately controlled with two external resistors and one capacitor. By applying a trigger signal, the
timing cycle is started and an internal flip-flop is set, immunizing the circuit from any further trigger
signals. To interrupt the timing cycle a reset signal is applied ending the time-out.

NOTES:
1. Supply Current is typically 1.0 rnA less when output is HIGH.

2. Tested at Vee = 5.0 V and Vee = 15 V.
3. This will determine the maximum value of RA + RS' For 15 V operation, the max total R == 20 MO.
4. For operating at elevated temperatures the device must be derated based on a +125° C maximum junction temperature and a thermal
resistance of +45 0 C/W junction to case for TO-5 and +150° C/W junction to ambient for both packages.

to Figure 1 the external capacitor is initially held discharged by a
transistor inside the timer.

until the set time has elapsed, even if it is triggered again during
this interval. The duration of the output H'IGH state is given by
t = 1.1 Rlel and is easily determined by Figure 3. Notice that since
the charge rate and the threshold level of the comparator are both
directly proportional to supply Voltage, the timing interval is inde·
pendent of supply. Applying a negative pulse simultaneously to the
Reset terminal (lead 4) and the Trigger terminal (lead 2) during the
timing cycle discharges the external capacitor and causes the cycle
to start over. The timing cycle now starts on the positive edge of the
reset pulse. During the time the reset pulse is applied, the output
is driven to its LOW state.

When a negative trigger pulse is applied to lead 2, the flip-flop is
set, releasing the short circuit across the external capacitor and
drives the output HIGH.The voltage across the capacitor, increases
exponentially with the time constant T = R1Cl. When the voltage
across the capacitor equals 2/3 Vee, the comparator resets the
flip·flop which then discharges the capacitor rapidly and drives the
output to its LOW state. Figure 2 shows the actual waveforms
generated in this mode of operation.
The circuit triggers on a negative-going input signal when the level
reaches 1/3 Vee. Once triggered, the circuit remains in this state
'Vce - 5 TO 15V

When Reset is not used, it should be tied high to avoid any
possibility of false triggering.

DUAL TIMING CIRCUIT
FAIRCHILD LINEAR INTEGRATED CIRCUIT

GENERAL DESCRIPTION - The "A556 Timing Circuits are very stable controllers for producing
accurate time delays or oscillations. In the time delay mode, the delay time is precisely controlled by
one external resistor and one capacitor; in the oscillator mode, the frequency and dutY cycle are both
accurately controlled with two external resistors and one capacitor. By applying a trigger signal, the
timing cycle is started and an internal flip-flop is set, immunizing the circuit from any further trigger
signals. To interrupt the timing cycle a reset signal is applied, ending the time-out.

PROGRAMMABLE TIMER/COUNTER
FAIRCHILD LINEAR INTEGRATED CIRCU ITS

GENERAL DESCRIPTION - The ,uA2240 Programmable Timer/Counter is a monolithic controller capable of producing accurate microsecond to five day time delays. Long delays, up to three
years, can easily be generated by cascading two timers. The timer consists of a

time~base

oscillator,

programmable 8-bit counter and control flip-flop. An external resistor capacitor (RC) network sets
the oscillator frequency and allows delay times from 1 RC to 255 RC to be selected. In the astable
mode of operation, 255 frequencies or pulse patterns can be generated from a single RC network.
These frequencies or pulse patterns can also easily be synchronized to an external signal. The trigger, reset and outputs are all TIL and DTL compatible for easy interface with digital system. The
timer's high accuracy and versatility in producing a wide range of time delays makes it ideal as a

FUNCTIONAL DESCRIPTION
(Figure 1 and Block Diagram, page 1)
When power is applied to the J.lA2240 with no trigger or reset inputs, the circuit starts with all outputs HIGH. Application of a positive-going trigger pulse to TRIG, pin 11, initiates
the timing cycle. The Trigger input activates the time-base
oscillator, enables the counter section and sets the counter
outputs LOW. The time-base oscillator generates timing pulses with a period T = 1 RC. These clock pulses are counted by
the binary counter section. The timing sequence is completed
when a positive-going reset pulse is applied to R, pin 10.

outputs are connected back to the Reset terminal (switch 51
open), the circuit operates in an astable or free-running
mode, following to a trigger input.
Important Operating Information
•

Once triggered, the circuit is immune from additional trigger
inputs until the timing cycle is completed or a reset input is
applied. If both the reset and trigger are activated simultaneously, the trigger takes precedence.

Ground connection is pin 9.

•

Reset R (pin 10) sets all outputs HIGH.

•

Trigger TRIG (pin 11) sets all outputs LOW.

•

Time-base TBO (pin 14) can be disabled by bringing the
RC input (pin 13) LOW via a 1 k resistor.

•

Normal Time-base Output TBO (pin 14) is a negativegoing pulse greater than 500 ns.
Note: Under the conditions of high supply voltages (VCC

> 7 V) and low values of timing capacitor (C < 0.1 J.lF, the

Figure 2 gives the timing sequence of output waveforms at
various circuit terminals, subsequent to a trigger input. When
the circuit is in a Reset state, both thetime-baseandthecounter sections are disabled and all the counter outputs are HIGH.

pulse width of TBO may be too narrow to trigger the counter section. This can be corrected by connecting a 300 pF
capacitor from TBO (pin 14) to ground (pin 9).

In most timing applications, one or more of the counter outputs are connected to the Reset terminal with 51 closed (Figure 3). The circuit starts timing when a trigger is applied and
automatically resets itself to complete the timing cycle when
a programmed count is completed. If none of the counter

•

Reset (pin 10) stops the time-base oscillator.

•

Outputs 00' .. 0128 (pins 1-8) sink 2 mA current with
VOL ';;0.4 V.

•

For use with external clock, minimum clock pulse amplitude should be 3 V, with greater than 1 J.lS pulse duration.

CIRCUIT CONTROLS
Counter Outputs (00 ... 0128' pins 1 thru 8)
The binary counter outputs are buffered open-collector type
stages, as shown in the block diagram on page 1. Each output is capable of sinking 2 mA at 0.4 V VOL' In the Reset
condition, all the counter outputs are HIGH or in the nonconducting state. Following a trigger input the outputs
change state in accordance with the timing diagram of Figure
2. The counter outputs can be used individually, or can be
connected together in a wired-OR configuration, as described
in the Programming section.

m is an integer, 1 ~ m ~ 10
Figure 5 gives the typical pull-in range for harmonic synchronization for various values of harmonic modulus, m. For
m < 10, typical pull-in range is greater than ±4% of timebase frequency.

RC Terminal (pin 13)
The time-base period T is determined by the external RC network connected to RC, pin 13. When the time base is triggered, the waveform at pin 13 is an exponential ramp with a period T = 1.0 RC.

Reset and Trigger Inputs (R and TRIG, pins 10 and 11)
The circuit is reset or triggered with positive-going control
pulses applied to pins 10 and 11 respectively. The threshold
level for these controls is approximately two diode drops
('" 1.4 V) above ground. Minimum pulse widths for reset and
trigger inputs are shown in Figure 22. Once triggered, the circuit is immune to additional trigger inputs until the end of the
timing cycle.

Time-8ase Output (T80, pin 14)
The time-base output is an open-collector type stage as shown
in the block diagram, page, 1, and requires a 20 kO pull-up
resistor to pin 15 for proper circuit operation. In the Reset
state, the time-base output is HIGH. After triggering, it produces a negative-going pulse train with a period T = RC, as
shown in the diagram of Figure 2. The time-base output is
internally connected to the binary-counter section and can
also serve as the input for the external clock signal when the
circuit is operated with an external time base. The counter
section triggers on the negative-going edge of the timing or
clock pulses generated at TBO, pin 14. The trigger threshold
for the counter section is'" +1.4 V. The counter section can
be disabled by clamping the voltage level at pin 14 to ground.

Modulation' and Sync Input (MOD, pin 12)
The oscillator time-base period, T, can be modulated by applying a dc voltage to MOD, pin 12 (see Figure 25). The timebase oscillator can be synchronized to an external clock by
applying a sync pulse to MOD, pin 12, as shown in Figure 4.
Recommended sync pulse widths and amplitudes are also
given.
The time base can be synchronized by setting the time-base
period T to be an integer mUltiple of the sync pulse period,
Ts' This can be done by choosing the timing components R
and C at pin 13 such that:

When using high supply voltages (VCC > 7 V) and a smallvalue timing capacitor (C < 0.1 pF), the pulse width of the
time-base output at pin 14 may be too narrow to trigger the
counter section. This can be corrected by connecting a 300 pF
capacitor from pin 14 to ground.

of the complex pulse patterns that can be generated. The
pulse pattern repeats itself at a rate equal to the period of the
highest counter bit connected to the common output bus. The
minimum pulse width contained in the pulse train is determined by the lowest counter bit connected to the output.

For low power operation with supply voltages of 6 V or less,
the internal time base section can be powered down by connecting Vee to pin 15 and leaving pin 16 open. In this configuration, the internal time base does not draw any current
and the overall current drain is reduced by "'" 3 mAo

OPERATION WITH EXTERNAL CLOCK
The pA2240 can be operated with an external clock or time
base by disabling the internal time-base oscillator and applying the external clock input to TBO, pin 14. The recommended
circuit connection for this application is shown in Figure 12.
The internal time base is de-activated by connecting a 1 kO
resistor from Re, pin 13, to ground. The counters are triggered on the negative-going edges of the external clock pulse.
For proper operation, a minimum clock pulse amplitude of
3 V is required. Minimum external clock pulse width must be
;;, 1 ps.

FREQUENCY SYNTHESIZER
The programmable counter section of the pA2240 can be
used to generate 255 discrete frequencies from a given timebase output setting using the circuit connection of Figure 13.
The circuit output is a positive pulse train with a pulse width
equal to T, and a period equal to (N + 1) T where N is the programmed count in the counter. The modulus N is the total
count corresponding to the counter outputs connected to the
output bus. For example, if pins 1, 3 and 4 are connected together to the output bus, the total count is N = 1 + 4 + 8 = 13;
and the period of the output waveform is equal to (N + 1) T
or 14 T. In this manner, 255 different frequencies can be synthesized from a given time-base setting.

FAIRCHILD. I1A2240
SYNTHESIS WITH HARMONIC LOCKING
The harmonic synchronization feature of the IlA2240 time
base can be used to generate a wide number of discrete frequencies from a given input reference frequency. The circuit
connection for this application is shown in Figure 14 (see
Figures 4 and 5 for external sync waveform and harmonic
capture range). If the time base is synchronized to (m)th
harmonic of input frequency where 1 .;:; m .;:; 10, the frequency fO of the output waveform in Figure 14 is related to the input reference frequency fR as

The circuit of Figure 14 can be used to generate frequencies
which are not harmonically related to a reference input. For
example, by selecting the external RC to set m = 10 and setting N = 5, a 100Hz output frequency synchronized to 60 Hz
power line frequency can be obtained.

STAIRCASE GENERATOR
The IlA2240 timer/counter can be interconnected with an
external operational amplifier and a precision resistor ladder
to form a staircase generator as shown in Figure 15. Under
Reset condition, the output is LOW. When a trigger is applied,
the op amp output goes HIGH and generates a negative-going
staircase of 256 equal steps. The time duration of each step
is equal to the time-base period T. The staircase can be
stopped at any level by applying a disable signal to pin 14,
through a steering diode, as shown in Figure 15. The count
is stopped when pin 14 is clamped at a voltage level';;;; 1.0 V.

where m is the harmonic number, and N is the programmed

Digital Sample and Hold Circuit

FAIRCHILD. JlA2240
DIGITAL SAMPLE AND HOLD
Figure 16 shows a digital sample and hold circuit using the
.uA2240. Circuit operation is similar to the staircase generator described in the previous section. When a strobe input is
applied, the RC low-pass network between the Reset and the
Trigger inputs resets the timer, then triggers it. This strobe
input also sets the output of the bistable latch to a HIGH state
and activates the counter.

ANALOG-TO-DIGITAL CONVERTER
Figure 17 shows a Simple 8-bit AID converter system using
the .uA2240. Circuit operation is very similar to that of the
digital sample and hold system of Figure 16. In the case of
AID conversion, the digital output is obtained in parallel
format from the binary-counter outputs with the output at
pin 8 corresponding to the most significant bit (MSB). Recycle time is = 6 ms.

The circuit generates a staircase voltage at the op amp output. When the level of the staircase reaches that of the analog input to be sampled, the comparator changes state, activates the bistable latch and stops the count. At this point, the
voltage level at the op amp output corresponds to the sampled analog input. Once the input is sampled, it is held until
the next strobe signal. Minimum recycle time of the system
is = 6 ms.

DIGITAL TACHOMETER TIME BASE
A digital tachometer requires a time-base generator to supply
two pulse outputs at specific intervals, e.g., every second. The
first pulse is a command (load) to transfer the accumulated
counts in the counter section into latches (memory); the second resets the counter to zero. A simple adjustable time base,
accurate to approximately ±O.5%, can be implemented using
the circuit in Figure 18.

"Driver" and "Motor Drive" circuitry is disabled when these limits are exceeded. If the condition continues for the duration set by the external stall timer
components, the circuit is latched off until reset by temporarily opening the power supply input line.
If stall timer protection is not required, Pin 12 should be grounded.

DC MOTOR SPEED CONTROL CIRCUIT
FAIRCHILD LINEAR INTEGRATED CIRCUIT

GENERAL DESCRIPTION-The IlA7392 is designed for precision, closed-loop, motor
speed control systems. It regulates the speed of capstan drive motors in automotive
and portable tape players and is useful in a variety of industrial and military control
applications, e.g., floppy disc drive systems and data cartridge drive systems. The device is constructed using the Fairchild Planar> epitaxial process.
The IlA7392 compares actual motor speed to an externally presettable reference voltage. The motor speed is determined by frequency to voltage conversion of the input
signal provided by the tachometer generator. The result of the comparison controls
the duty cycle of the pulse width modulated switching motor drive output stage to
close the system's negative feedback loop.

CONNECTION DIAGRAM
14-PIN DIP
(TOP VIEW)
PACKAGE OUTLINE SA, 9A
PACKAGE CODES D P

Thermal and over-voltage shutdown are included for self-protection, and a "stalltimer" feature allows the motor to be protected from burn-out during extended mechanical jams.
The IlA7392 is a low current compliment to the IlA7391 for those applications requiring
less current and also to drive high current output stages for very high current applications.

INTRODUCTION

Digital signals transmitted any distance, only a few inches in
some cases or up to several miles, must enter the analog world
of transmission lines before arriving at their digitial destinations. Therefore, special attention should be given to the
interface between the digital and analog areas- often one of
the least understood considerations in a system design.
Interface problems occur every time a digital signal is sent
from a printed circuit board and, indeed, transmission line
theory must often be considered when connecting devices on
the same board when using very high -speed logic such as ECL
or Schottky TTL. This section is intended to shed some light on
this important design procedure- interfacing of systems (or
subsystems) for the transmission of information from one
location to another via line drivers, transmission lines and
line receivers.

Section two discusses the general characteristics of transmission lines and their derivations. Here, using a transmission
line model, the important parameters of characteristic impedance and propagation delay are developed in terms of their
physical and electrical parameters.
The third section explores another important characteristicreflection coefficient. This concept is combined with the
material in section two to present graphical and analytical
methods for determining the voltages and currents at any
point on a line with respect to distance and time after signal
application. The effects of various source resistances and line
termination methods on the transmitted signal are discussed.
In section four, the logical progression from the ideal transmission line to the real world of the long transmission line with
its attendant losses and problems is made; specifically, the
methods to determine the practicality of a certain length of
line at a given data rate is discussed. Transmission line effects
on various data formats are examined as well as the effects of
several types of sources (drivers) on signal quality. A practical
means is given to measure signal quality for a given transmission line using readily available test equipment. This, in
turn, leads to a chart that provides the designer a way to predict
the feasibility of a proposed data -transmission circuit when
twisted - pair cable is used. A method to estimate signal quality
on coaxial-cable interconnections is also discussed.

To design a data transmission interface, the systems designer
must be familiar with several subjects. He needs a good
understanding of the effects of pulse excitation on transmission lines, knowledge about the various fundamental forms
and modes of data -transmission -line circuit operation, and
familiarity with the problems encountered when operating
with long transmission lines. He must also have a good working knowledge of line drivers and line receivers, their electrical
characteristics, and how and where these devices should
be used.

This section is not intended to be a textbook in the formal
sense, nor is it a 'cookbook' of applications since each system
must be designed based on its unique requirements. It is
presented as a refresher on the basics of pulse transmission
line theory combined with methods for determining signal
quality and feasibility of the particular data transmission
system. Only those areas that directly affect the transmission
of digital signals are covered. This section contains the
essential elements to aid the system designer in making an
informed decision regarding the quality of data received at the
end of a transmission line.

Section five describes the various combinations of forms and
modes of operation in data -transmission systems. Also
described are the circuits that conform to industry standardsEIA RS232C, MIL STD l88C and IBM 360/370 I/O interfaces.
A selection guide for available line drivers and receivers integrated circuits and some helpful suggestions for incorporating
them into a system complete the section.

In section six, new EIA standards of RS -422 and RS -423
specifications are discussed.

DATA TRANSMISSION LINES AND THEIR CHARACTERISTICS
INTRODUCTION
A data transmission line is composed of two or more conductors transmitting electrical signals from one location to another. A parallel transmission line is shown in Figure 2-1. To
show how the signals (voltages and currents) on the line relate to as yet undefined parameters, a transmission line model
is needed.
TRANSMISSION LINE MODEL
Because the wires A and B could not be ideal conductors, they
therefore must have some finite resistance. This resistance/
conductivity is determined by length and cross-sectional area.
Any line model, then, should possess some series resistance
representing the finite conductivity of the wires. It is convenientto establish this resistance as a per-un it-length parameter.
Similarly, the insulating medium separating the two conductors could not be a perfect insulator because some small leakage current is always present. These currents and dielectric
losses can be represented as a shunt conductance per unit
length of line. To facilitate development of later equations,
conductance is the chosen term instead of resistance.

where E is the electric field in volts per meter, q is the charge
in Coulombs, E is the dielectric constant, and r is the distance
in meters. These free charges, accompanied by a voltage,
represent a capacitance (C = q/V); so the line model must include a shunt capacitive component. Since total capacitance
is dependent upon line length, it should be expressed in a capacitance per-un it-length value.
It is known that a current flow in the conductors induces a
magnetic field or flux. This is determined by either Ampere's
law

(2.3)

or the Biot-Savart law
If the voltage between conductors A and B is not variable with
time, any voltage present indicates a static electric field between the conductors. From electrostatic theory it is known'
that the voltage V produced by a static electric field E is given
by

Cascaded Network to Model Transmission Line

Since it is assumed that the line model in Figure 2-5a is infinite in length, the impedance looking into any cross section
should be equal. that is, Zl =Z2 =Z3' etc. So Figure 2-5a can
be simplified to the network in Figure 2-5b where Zo is the
characteristic impedance of the line and Zin must equal this
impedance (Zin =ZO). From Figure 2-5b,

Zin = Z

such that the wl and wC terms are much larger respectively
than the Rand G terms, Zs = j w ! land Zp =1/ j w I C can be
used to arrive at a lossless line value of

In the lower frequency range,~

Multiplying through both sides by (ZO + Zp) and collecting
terms yields

the Rand G terms dominate the impedance giving

zo=~

(2.10)
which may be solved by using the quadratic formula to give

A typical twisted pair would show an impedance versus
applied frequency curve similar to that shown in Figure 2-6.

(2.11)

Zo

The Zo becomes constant above 100 kHz, since this is the
region where the wl and wC terms dominate and Equation
2.13 reduces to Equation 2.14. This region above 100 kHz
is of primary interest, since the frequency spectrum of the
fast rise/fall time pulses sent over the transmission line have
a fundamental frequency in the 1-to-50 MHz area with harmonics extending upward in frequency. The expressions for

Substituting in the definition of Zs and Zp from Equations 2.7

Now, as the section length is reduced, all the parameters

is because the per-un it-length line parameters R, l, G, and C
are constants for a given line. By sufficiently reducing I,
the terms in Equation 2.12 which contain I as multipliers

Input Current Into a 96n Transmission Line for a 2 V Input Step for Various Line Lengths

Zo in Equations 2.13, 2.14 and 2.15 do not contain any ref·
erence to line length, so using Equation 2.14 as the normal
characteristic impedance expression, allows the line to be
replaced with a resistor of RO = Zo n neglecting any small
reactance. This is true when calculating the initial voltage
step produced on the line in response to an input current step,
or an initial current step in response to an input voltage step.

Figure 2-7 shows a 2 V input step into a 96n transmission
line (top trace) and the input current required for line lengths
of 150, 300, 450, 1050, 2100, and 3750 feet, respectively
(second set of traces). The lower traces show the output volt·
age waveform for the various line lengths. As can be seen,
maximum input current is the same for all the different line
lengths, and depends only upon the input voltage and the
characteristic resistance of the line. Since RO = 96n and
vin = 2 V, then iin = vin/RO ~ 20 mA as shown by Fig·
ure 2-7.

=~ x
10 ns

.06 /LF

where C is the total capacitance of the line (C = C per foot x
length of line) and dv/dt is the slew rate of the input Signal.
If the 3750·foot line, with a characteristic capacitance per
unit length of 16 pF/ft is used the formula Ctotal (C x I )
would yield a total lumped capacitance of .06 jJF. Using this
C(dv/dt) = i formula with (dv/dt = 2 Vll0 ns) as in the scope

=

12 A

This is clearly not the casel Actually, since the line impedance
is approximately lOOn, 20 mA are required to produce 2 V
across the line. If a signal with a ri!le time long enough to
encompass the time delay of the line is used, (tr »t) then the
C(dv/dt) = i formula will yield a reasonable estimate of the
peak input current required. In the example, if the dv/dt is
2 V120 jJS, (tr = 20 jJs > t = 6 I-Is) then i = 2 V 120 I-IS x 0.06 I-IF
= 6 mA. which is verified by Figure 2-8.

There will probably be some phase shift and loss of signal v2
with respect to v1 because of the reactive and resistive parts
of Zs and Zp in the model (Figure 2-5bj. Each small section
of the line ( I ) will contribute to the total phase shift and am·
plitude reduction if a number of sections are cascaded as in
Figure 2-5a. So, it is important to determine the phase shift
and signal amplitude loss contributed by each section.

Equation 2.28 shows that the lossless transmission line has
one very important property: signals introduced on the line
have a constant phase shift per unit length with no change in
amplitude. This progressive phase shift along the line actually represents a wave traveling down the line with a velocity
equal to the inverse of the phase shift per section. This
velocity is

for loss less lines. Because the LRCG parameters of the line
are independent of frequency except for those upper frequency constraints previously discussed, the signal velocity given
by Equation 2.29 is also independent of signal frequency. In
the practical world with long lines, there is in fact a frequency
dependence of the signal velocity. This causes sharp edged
pulses to become rounded and distorted. More on these long
line effects will be discussed in Chapter 3.

REFLECTIONS: COMPUTATIONS AND WAVEFORMS
INTRODUCTION

Substituting vin/RO for iin and collecting terms shows

In Section 2 it was determined that transmission lines have
two important properties: one, a characteristic impedance
relating instantaneous voltages and currents of waves traveling along the line and, two, a wave propagation velocity or
time delay per unit length. In this chapter, both Zo and [,
are used to compute the line voltages and currents at any
point along the line and at any time after the line signal is
applied. Also, concepts of reflections and reflection coefficients are explored along with calculating methods for voltages and currents.

This shows that both source and characteristic resistances act
as voltage dividers for the source voltage V. Figure 3-2 shows
voltage and current steps for the various source resistances.
Source resistances of less than Ra produce initial voltage
steps on the line which are greater than half the compliance
of the source voltage, V. A matched source (RS = Ra) produces voltage steps exactly half of V and source resistances
greater than Ra produce an initial voltage step less than one
half V in magnitude. Generators can be classified into three
categories:

THE INITIAL WAVE
Section 2 also showed that for most practical purposes,
where fast rise and fall time signals are concerned, the characteristic impedance of the line actually behaves as a pure
resistance (RO =y'L/C).

Figure 3-1 a shows a generator comprised of a voltage source
(magnitude V), a source resistance of RS ohms, and a switch
closing at time t = 0 connected to a lossless, infinite length
transmission line having a characteristic resistance, RO'
Because the relationship of vin to iin is known as vin = RO iin'
the lossless transmission line can be replaced with a resistor
as shown in Figure 3-1b. The loop equation is

Waveforms of these types will be discussed more fully in
section 4 on long line effects. Suffice to say that initial voltage wave amplitude depends greatly on source resistance.
Voltage source type drivers produce higher amplitude initial
voltage waves in the line than either matched source or current source type drivers .

CUT LINES AND A MATCHED LOAD
In examining an infinite, loss less line (Figure 3-3), it is already
known that the ratio of line voltage to current is equal to the
characteristic resistance of that line. The line is lossless, and
the same voltages and currents should appear at point x down
the line after a time delay of xli. If the line at point x is cut,
and a resistor of value RO is inserted, there would not be a
difference between the cut, terminated finite line and the infinite line. The Vx and ix waves see the same impedance
(RO) they were launched into at time t = 0, and indeed, the
waves are absorbed into RL (= RO) after experiencing a
time delay of T = x Ii. So, from an external viewpoint, an infinite-length lossless line behaves as a finite-length lossless
line terminated in its characteristic resistance.

(3.6)

and voltage across the load is

To find the ratio of vr to Vx so that it can be ascertained how
much power is absorbed by the load, and how much is not
absorbed (therefore, reflected), substitute vx/RO for ix and
vr/RO for ir into Equation 3.6.

When a traveling wave vx ' ix meets a boundary such as the

Since vr/vx = PL. then vr = PL Vx = 0 and no reflection is
generated. This agrees with the discussion of cut lines and
matched load where a line terminated in its characteristic
impedance behaves the same as an infinite line. All power
delivered by the line is absorbed into the load. The waveforms appear as shown in Figure 3-5. The wave starting at
the source at time t =0 is reproduced at point x down the line
after a time delay of t =x 8 = T

(3.22)

This agrees exactly with Equation 3.21 and will always be
the case. After all reflections cease and the circuit reaches
equilibrium. the steady state voltages and currents on the
line are the same as those produced using simple dc circuit
analysis. Waveforms for RL > RO (specifically RL = 3 RO)

er than can be instantaneously absorbed by the load, the excess power is returned to the source and absorbed in the
source resistor (assuming RS = RO)'

This agrees with the result of Equation 3.27. The waveforms
for Case 3 (RL < RS) appear in Figure 3-7.

An upper limit on the voltage reflection coefficient is found
by allowing RL to go to infinity. In this case, Equation 3.13
goes to +1.

An interpretation of the actions occurring when load resistance is less than the characteristic line resistance is as follows: when power available at the line end is less than the
power the load can absorb, a signal is sent back to the source
saying, in essence, "send more power".

in the down direction, to represent the location on the line under examination. Because voltages at the source and load
ends of the transmission line are normally of primary interest,
two time scales are necessary. Drawing arrows from one time
scale to the other as in Figure 3-10 shows the direction oftravel of the waves during a specific time interval. Since the main
concern is only with the waveforms at the line ends, time
scales are ruled off in multiples of the time delay of the line
T. If a unit-step type wave is launched from the source at
time t = 0+, it is known that the magnitude of the wave will
persist unchanged until a wave arrives back from the load
after a round trip delay time of two line delays. The source
time scale then is incremented in multiples of 2mT where
m = 0, 1, 2, 3, . . . likewise, the first wave arrives at the
load after a single time delay, so the first increment ruling
on the load time scale is T, or one time delay of the line. Because the subsequent waves arrive back at the load in increments of 2 t ,the load time scale is ruled off in multiples of
(2m + 1) t where m = 0,1,2,3, . . . The operation of the lattice diagram is discussed using the example in Figure 3-10b
which is the lattice diagram for the associated circuit.

The first wave vi(l) is launched at the source and begins to
travel toward the load end of the line. As previously mentioned, a voltage divider action between RS and RO is used
to derive the magnitude of the initial voltage wave.

It has also been established that the steady state solution for
voltages and currents on the line can be found by simple dc
circuit analysis.
In examining reflection effects for the remainder of this book,
the following conventions are used.

At this time, the voltage at the source is the sum of the initial
voltage plus the voltage wave vi(l) just generated.
A voltage or current wave traveling toward the point of interest will have the subscript "i" for incident wave.

RO

us(O+) = Us (0-) + ui(1) = 0 + V - - RO + Rs

A voltage or current wave traveling away from the point of
interest will have the subscript "r" for reflected wave,

Because the switch closure represents a step function, the
source voltage remains at this level until a wave returns
after reflecting from the load at time t = 2 T

The subscript "s" means the parameter applied to the
source (vS for the voltage at the source, etc.), and

time t =

The incident voltage wave vi(l) now arrives at the load
and generates a reflected voltage wave

The subscript "L" means the parameter applied to the load
(vL for the voltage at the load, etc.)

The reflected voltage wave v r(l) immediately starts traveling back toward the source becoming the incident voltage wave vi(2) which arrives back at the source at t = 2 T .

to pause at this point and examine the models used by the
lattice diagram.

This is the sum of the voltage that was there before the wave
arrived, i.e., vL(m-2), plus the wave arriving vi(m) and the
reflected wave vr(m) departing.

First, both the line driver and receiver are simulated either by
a constant input or output resistance. The source has two
voltage sources and a switch representing the internal source
voltage at a time less than zero and equal to (or greater than)
zero. The receiver is represented by a single resistor shunting
the line end opposite the driver site. The line itself is represented by its characteristic resistance RO and its total oneway time delay ( T). This is equal to length times propagation
delay per unit length. This model is shown in Figure 3-".

If m is even, the vi(m) wave is arriving at the source and generates a reflected wave

This becomes vi(m+l) as it starts toward the load. The voltage at the source is now
vs(m)

= vs(m - 2) + vj(m) (1 + Ps)

Because most data communication circuits are voltage types,
that is, the receiver senses the line voltage to decide if a logic
One or logic Zero is present, the primary interest is in voltages
at the source and load as a function of time. Major exceptions
include the current loops used in teletypewriters, telegraphs,
and burglar alarm systems. The majority of data communications circuits used in computers, peripherals, and general
controllers are voltage types.

This is the sum of the voltage that was present vs(m-2) plus
the incident wave arriving vi(m) plus the reflected wave departing vr(m).
The voltage and current at the source end of the line for a lossless line can be expressed as a summation.

to 3 T may cause breakdown of the input circuitry of a receiver, depending on the receiver voltage rating. The undershoot
at t = 3 T to 5 T can reduce the noise immunity of a receiver
or even cause a logic level misinterpretation - an error in the
data. These waveforms are shown in Figure 3-12a.

istics such as found in diodes, a graphic method can be used
called the reflection diagram or the Bergeron* method.
Signals exchanged using lattice diagrams are of the unit step
variety. When ramps or more complex waves are exchanged,
the complexity of the bookkeeping increases dramatically.
Additionally, the lines are presumed to be lossless, although a
constant line attenuation factor could be accommodated without excessive bookkeeping. These limitations should be kept
in mind when examining various source and load resistance
combinations and their reflection characteristics.

If RL is less than RO' then PL is negative and a wave arriving
at the load generates a reflection opposite in polarity to the
incident wave. This causes the voltage at the source to overshoot steady state voltage at t = O. Each reflection returning
from the load causes the source voltage to continually step
down toward the steady state voltage VSS. These steps last
for 2 T , or one round trip delay. Load voltage starts an increasing step-up waveform towards VSS at time t =T , with
steps again taking one round trip delay, 2 T . A line receiver
placed in the middle of the line sees an entirely different
waveform - dampened oscillations much like the load voltage in Figure 3-12a. This is caused by the negative signs of
both source and load voltage reflection coefficients. Each
time an incident wave arrives at either source or load, the
reflected wave generated at that time has a sign opposite to
the sign of the incident voltage wave. The voltage at a distance half way down the line is composed of these forward
and reverse traveling waves arriving at that point commencing
at time t = 0.5 T , and with each new wave passing that point
after one line delay ( T). These waveforms are shown in Figure 3-12c.

There are three classes of source resistance, RS < RO' RS = RO
and RS > RO. There are also three classes of load resistance,
RL < RO' RL = RO and RL >RO. This gives nine types of single
driver, single receiver line circuits. Each circuit will be examined in turn to determine reflection effects for these combinations with evaluations of each combination for voltage type
communications.
REFLECTION EFFECTS FOR VOLTAGE SOURCE
DRIVERS
Initial waves launched by a voltage source type driver (RS < RO)
are greater than one-half the magnitude of the internal voltage source. Referring to Figure 3-11, the initial voltage wave
is derived as follows.

vp)

(3.36)
The optimum load resistance for voltage signal communications on transmission lines driven by a low impedance source
(RS < RO) is equal to the characteristic line resistance. Large
signal line voltages are produced and there are no reflection
effects complicating the waveforms (Figure 3-12b).

while the voltage at the source at t = 0+ is

However, a matched load (R L =RO) is a dc load on the driver,
thus it increases system power dissipation. But, it does preserve signal fidelity and amplitude allowing use of multiple
bridging receivers (Rin»RO) along the line.

If the receiver switching point is at the mean of the driver
voltage swing, the initial wave always has sufficient magnitude to indicate the correct logic state as it passes the receiver
site. This maximizes the noise margins of the receiver.
Since RS < RO' the source voltage reflection coefficient PS
is less than zero. Any voltage waves, then, arriving back atthe
source are changed in sign, reduced in amplitude (assuming
RS > 0 n), and sent back toward the load. If the load resistance equals the characteristic line resistance (RL = RO), the
voltage reflection coefficient of the load is

o
2RO

The unterminated case (R L > RO) reduces dc driver loading
and also reduces system power dissipation over the matched
load case. The unterminated case does, however, allow the
load signal to exhibit pronounced overshoot and undershoot
around the steady state voltage. If the load signal undershoot
places the receiver in its threshold uncertainty region, data
errors result. There is a way to" civi lize" the voltage waveform
of the unterminated line load by trading off signal rise time
versus line time delay. This is discussed later.

o

No reflections, therefore, are generated at the load. The voltage wave produced at the source is reproduced at the load
after a time delay of T = lUi , and the line assumes a steady
state condition. Figure 3-12b illustrates the source and load
voltage waveforms for this case.

The final case of RS < RO and RL < RO is not generally
useful in terms of voltage signals produced (Figure 3-12c.)
Systems using this case consume more power than the previous two cases and have no particular advantage for voltage mode communications.

If RL is greater than RO' PL is positive. Waves arriving at the
load generate the same polarity reflections as the arriving
waves. Ps and PL are of opposite signs, so a dampened oscillatory behavior of the load voltage is expected. The oscillation period or ringing is 4 T . The overshoot of vL from t = T

will be close to +1.0. Because source resistance is set equal to
line resista nce, P S becomes zero, the reflected voltage wave
from the load is absorbed by the source at time t = 2 T , and
steady state conditions prevail. Waveforms for this case are
shown in Figure 3-12d, This is called back matching or series
termination.

(3.39)

Assume, for clarity, that initial voltage (VO-) is zero, thus
Equation 3.39 simplifies to
Vs (0+)

The main advantage of series termination is a great reduction in steady state power consumption when compared with
the parallel terminated case (RS« RO' RL =RO)' At the same
time, series termination provides the same Signal fidelity to a
receiver placed at the line end. Compare the load voltage
waveforms for the two cases in Figure 3-12b and 3-12d. The
main disadvantage to series termination is that receivers
placed along the line see a waveform similar to that shown
for the source in Figure 3-12d. That is, receivers along the
line see the VO+/2 initial wave as it passes that point on the
line, and do not see a full signal swing until the load end reflection passes that point. Consequently, receivers along the
line do not see a signal sufficient to produce the valid logic
state output until the load reflection returns. Depending on
actual line length and receiver characteristics, the receiver
may even oscillate, having been placed in its linear operation
region. With the benefit, then, of reducing system power,
the series termination method has a constraint of allowing
only one line receiver located at the line load end. The parallel termination method should be used if other receivers along
the line are required.

(3.40)

Since RS = RO' Ps is equal to zero. This means that
load-generated reflections due to load mismatch are absorbed
at the source when, at time t = 2 T ,the reflected wave arrives back at the source. The line then assumes a steady state
throughout. This back match or series termination effect of a
matched source allows a wide latitude in choice of load resistance without sacrificing the signal fidelity of the load voltage
waveform.
If the load resistance equals the characteristic line resistance
RL = RO' then PL equals zero and no load site reflections
are generated. The initial voltage wave arrives at the load at
time t = T (one line delay) and voltages (and currents) on the
line immediately assume steady state conditions (see Figure
3-12e). The optimum receiver threshold here is one-half the
steady state voltage or VO+/4. The main advantage over the
voltage source type driver with matched load case (RS < RO'
RL = RO) is that RS and RL resistance tolerances may be relaxed without incurring much signal ringing. This effect is
due primarily to the termination provided by both line ends,
rather than just one line end. Any reflected voltage wave on
either system is attenuated by the product of Ps and P L for
each round trip line delay time. Since the Ps PL product
for the fully matched case is smaller than the PS PL product for the single matched case, the reflections are attenuated and die out in fewer round trips. For example, if 20%
tolerance resistors are used in both cases, Ps and PL values
for the fully matched case become 0.0 ± 0.0909, which is a
Ps PL product of ± 0.0033. This means that after one round
trip (2 T ), the reflection amplitude starting back toward the
load would be less than 0.33% of the initial wave.

The final case of matched source drivers is with the use of a
load resistance less than the characteristic line resistance.
The waveforms for this case are shown in Figure 3-12f. A
line receiver with a threshold of V 014 placed at the source
responds like a positive, edge triggered one-shot and produce
a pulse in response to a +V 12 initial wave of 2 T duration.
Aside from its use as a one-shot, this circuit doesn't seem to
offer any advantages for voltage mode communications.

REFLECTION EFFECTS FOR CURRENT-SOURCE
DRIVERS
The name current source drivers is somewhat of a misnomer,
and might be more properly called current-limited voltage
source drivers. True current source drivers such as the 75110
are normally used in conjunction with parallel termination
resistors to create a matched source.

Using RS = 10 n, RL = 100 n, and RO = 100 n as for Figure 3-12a, shows the same 20% tolerances applied to the single matched case

The current source drivers (RS > RO) discussed resemble true
current sources in the respect that their output resistance is
usually much greater than the characteristic line resistance.
The initial voltage step produced on the line is thus usually
small vi(l) = (i!!(1 )RO)' This is due to the voltage divider
action of the driver source resistance and the characteristic
line resistance.

+0.0909

0.0774

The voltage reflection amplitude after one round trip is a
maximum of 7.7% of the initial wave.
The choice between using the single and fully matched system should be carefully considered because the fully matched
system does sacrifice signal voltage magnitude to get a decreased dependence on absolute resistor values.

Voltage waveforms for a current source type driver either
step up to VSS' reach steady state after 2 T , or execute
a dampened oscillation around VSS' depending on whether
the load resistance RL is greater, equal, or less than RO' respectively. The second case RL = RO provides signals much the
same as the other two cases where RL = RO' that is, the
source voltage steps immediately to VSS' with the load voltage following after one line time delay. Here the amplitude of

the signal is much smaller than previous matched load cases.
Since the current source type drivers (75109/110) have
high off-state impedances, they allow multiple drivers on the
line to produce a data bus or party line. This aspect will be
discussed in more detail in Chapter 5. Waveforms for the
matched load case are shown in Figure 3-12h.

The RL> RO case is of interest because it is representative
of DTL driving a transmission line with the output going from
LOW to HIGH. DTL has a high value RS' (2 kn or 6 kn ) in
the HIGH logic state. Since both RS and RL are greater than
RO*' both Ps and PL are positive. A small voltage step
starts from the source at t = 0+; its magnitude is

The case RL < RO really provides no useful advantage for
voltage mode communications. The negative sign for PL
and the positive sign for Ps lead to dampened oscillatory
behavior, or ringing. The maximum perturbation takes place
at the source end of the line. Waveforms for this case are similar to those shown in Figure 3-12a, and are shown to scale in
Figure 3-12i. With the given values used to produce the figure, the maximum amplitude ringing appears at the source

Upon arrival at the load at time t = 7 , this initial wave generates a positive voltage reflection since P L >0. The voltage
reflection arrives back at the source site at time t = 2 7 . Since
Ps is also positive, another positive voltage reflection is
launched back toward the load. The process repeats, and the

reflection effects of Case 1 but, at the same time, does
require a driver circuit to have its internal current limits
set at greater values than those required to produce the desired signal level into the minimum line resistance used.
Thus, this case requires power buffer gates such as the
9N40 or 9S 140 or specific line driver devices such as the
9612, 96149621 or 8T13123. Ordinary TTL, except for
the above mentioned circuits, has too Iowa current limit
point to adequately drive 50 n lines.

SUMMARY - Which are the Advantageous
Combinations?
In examining the basic combinations of source, line and load
resistances, and typical waveforms characteristic of each
case, advantageous combinations can be determined. The
primary results are tabulated in Figure 3-15. Those combinations generally used in voltage mode communications circuits
are as follows.
1. Unterminated case (RS «RO' RL» RO). This situation
provides low steady state power dissipation and large
signal levels, but also shows pronounced "ringing" effects.
The "ringing" can be reduced by controlling signal rise/fall
time versus T, or by clamping diodes to limit load signal
excursions. This case is representative of TTL circuits and
is thus widely employed.

3. The series terminated or backmatched driver case RS = RO
Rt-»RO provides a low steady state power dissipation
system for use with one receiver located at the load end of
the line. The positive reflection coefficient of the load is
used to approximately double the initial wave arriving at
the load. Setting RS = RO terminates the reflected wave
when it arrives back at the source site after two line delays,

of other receivers located along the line is not recommended, because they will not see the full driver signal swing

(shown as solid lines) are the superposition of the waves represented by the dotted lines. With the exception of a slight
rounding of the edges, the actual waveforms for the circuit,
shown in the oscilloscope photograph in Figure 3-17, closely
approximate the waveforms predicted by theory.

bridging points. Such receivers could malfunction, as they
would see a voltage very close to their threshold, and perhaps even place the line receiver in its linear operating
region. This could make the line receiver sensitive to oscillatory, parasitic feedback. If these contraints are acceptable, the series termination method can be used to good
advantage in providing the same signal fidelity and signal
amplitude as with the parallel termination method, while
at the same time, contributing a significant savings in
steady state power consumption.

If the source excitation is adjusted so that its O-to-1 00% rise
time tr is equal to 2 T , each of the Vi + vr and ii + ir waveforms must be modified to include this rise time. The waves
will have the same final value as predicted by the lattice diagram, but they now require two line time delays to reach this
final value. The vl, Vs and is waveforms consist of the
superposition of these linear ramps. Because each wave
reaches its final value just as a new wave arrives, their superposition converts the square edged vl' vs and is waveforms
into triangular waveforms. This is shown in Figure 3-18. The
accompanying oscilloscope photograph shows the close correspondence between the actual and theoretical waveforms
whereas an additional oscilloscope photograph in Figure 3-18
shows the actual waveforms for the case where tr = T. Not
surprisingly, the tr = T case changes the vl' Vs and is
waveforms of the tr «T case into trapezoidal forms because
each arriving wave reaches its final value well before a new
wave arrives.

4. The fully matched case RS = RO' Rl = RO not only provides excellent signal fidelity all along the line, but also
has reduced signal amplitude over that of the parallel terminated case. Additionally, the power consumption is
somewhat less than the parallel termination case and the
power is divided equally by the source and load. The primary advantage of the fully matched system is that termination resistor tolerances can be relaxed somewhat with·
out incurring large amounts of ringing. This is because both
the source and load act as line terminations.

EFFECT OF SOURCE RISE TIME ON WAVEFORMS
Previously, it was assumed that the source-produced signal
rise time was always much less than the line time delay ( T ).
Because the waveforms for the source and load voltage were
the superposition of incident and reflected waves occurring
at their proper times, and because the shape of each wave was
a square edged step function, the resultant source and load
waveforms were thus also square edged, or ideal in nature.
In many practical cases, particularly when line length is short,
the source excitation possesses a finite, and non-negligible,
rise time. Therefore, depending on the ratio of rise time to
line delay, it is possible to have a new wave start arriving at
the point of interest before the previous wave can reach its
final value. The net waveform for voltage or current at that
point, then, would consist of the superposition of two or more
waves during their time of overlap. To study the superposition
effect on Signal waveforms, the source excitation is represented as a simple linear ramp rise to its final value of VO+' so

and

e(t)

If the source excitation is adjusted such that its rise time
equals three line delays tr = 3 T , the Vi + vr and ii + ir waves
overlap for a period of time equal to T. That is, each wave
reaches only 2/3 of its final value when a new wave starts
arriving. Considering the waveform, the load voltage from
time T to 3 T is

begins arriving from the source, and the load voltage then is
the superposition of these two waves. Because vi(3) is a negative wave ( Ps <0), the algebraic sum of the last third of the
first wave and the first third of the second wave vi(3) arriving
at the load causes the load voltage to reduce in amplitude
from the (t r « T) case. likewise, the source voltage and source
current show reduced amplitudes over the ideal case, due to
the overlap period of the waves arriving at the source.

where tr represents the O-to-1 00% source rise time. The circuit model and its lattice diagram are shown in Figure 3-16.
The values of RS' RO and Rl were chosen to equal those of an
actual circuit on hand, allowing the theoretical waveforms,
obtained by graphical superposition, to be compared with the
measured response of an actual circuit.

Theoretical and actual waveforms for the tr = 3 T case are
shown in Figure 3-19. Notice that load voltage perturbations
and source current is requirements are reduced from those
of the tr« T case. Similarly, the ratio of tr to T , can be
successively increased. This results in reduced ringing on the
load voltage and reduced source current due to the overlapping of more and more Vi + vr (or ii + ir) waves. Actual
and theoretical waveforms for tr equal to 4 T , 6 T and 8 T
are shown in Figures 3-20, 3-21 and 3-22, respectively. In
each case, as the tr to T ratio is increased, the instantaneous
source and load voltages become more equal. The source
current is also reduced so that the circuit exhibits fewer reflection effects and the transmission line itself can be considered
as a simple interconnection from dc circuit theory.

Figure 3-17 shows the load voltage vl, source voltage Vs
and source current is waveforms versus time for a circuit
with a source rise time very much less than T. The actual
waveforms for vl' vs and is are composed of the superposition of both incident and reflected waves in their proper time
sequence. In the figures, these waves are shown as dotted
lines. Each wave represents the sum of the incident wave
plus its reflection. The resultant vl, Vs and is waveforms

words, if the stub's time delay is made very short when compared to the tr of the signal at the stub line location, the
stub reflections will have a minimal effect on the line signals.
A stub length to generate a tr: T ratio of greater than 8: 1 is
usually considered adequate to negate the stub reflections.

Using the tr: T ratio to reduce reflection effects has many
practical advantages in digital design. The low source and
high input resistance of TTL or ECl circuits allows one gate to
drive many receiving gates. The reflection effects of this unterminated combination, however, can cause data errors or
at least lead to reduced noise immunity due to the pronounced
load voltage undershoot. Since the rise and fall times of
these devices are easily measured, a maximum line length
can be set such that ttie resulting tr to T ratio provides
the desired reduction in ringing. This is the primary basis for
the wiring rules of each logic family and, usually, the tr to T
ratio is chosen somewhere between 3:1 and 4:1. As an example, the rise and fall time for normal TTL (9N/74N series)
is t1 0%-90% = 6 ns. When this is converted to an equivalent
linear 0 to 100% time, tr = 8 ns. A common propagation
delay of 1.7 ns/ft, in combination with the requirement
that tr = 3 T , gives the maximum line length of approximately 18 inches. This corresponds with the published recommendation of the various manufacturers for the 9N/74N
series TTL circuits. A similar computation of the rise and fall
times for other logic families yields their respective line length
recommendations. The faster families require shorter line
lengths for the same tr to T ratio, and slower logic families
allow relatively longer line length. This ratio can also be
used to make stubs or taps on lines "disappear". In other

The third primary application of the tr to T ratio for controlling reflection effects is that used in some standard data
communications interfaces such as EIA-RS232-C. Here, driv··
er slew rate is explicitly controlled. This, along with the implied maximum interconnect cable length serves to produce
a tr: T ratio of 3: 1 or greater. This, in turn, reduces the reflection effects inherent in a voltage source driver, unterminated line system. The main disadvantage of using the tr: T
ratio to control reflection effects is in the overall time for the
signal representing the data to rise above the receiver threshold level. With the parallel terminated method, the minimum
time delay was T or one line delay. When the tr: T ratio
is used, an additional delay time of approximately 0.5 tr is
added to the line delay yielding, therefore, a greater effective signal propagation delay. This increased delay mayor
may not be acceptable in the desired system so the trade-off
between ease of usage of the unterminated case must be
weighed against the increased effective signal delay over
that delay obtainable with the terminated case.

'(G/C), the distortionless line is only of historical
interest, and it is not possible to satisfy the (R/L)=(G/C)
condition over a sufficiently wide bandwidth to allow a proper
transm ission of short duration pulses. Over a lim ited frequency
range such as that encountered in telephony (0-4 kHz), the L
term can be increased by either adding lumped inductances
at fixed intervals along the line or by winding a magnetic
material (as a thin tape) around the conductors of the line
throughout its length. Lumped loading is commonly applied
to long telephone circuits to reduce the signal attenuation
over a narrow frequency range; however this linearity is at
the expense of in-band attenuation and non-linear delay distortion. The distributed loading method has been tried, but
the mechanical characteristics of the magnetic materials
have made the winding process very difficult. In any event,
neither method allows short pulses to retain their wave
shapes. The interest in line loading to produce the Heavyside
condition for pulse transm ission is therefore largely academ ic.

Engineers designing data transmission circuits are not usually
interested in the esoterica of lossy transmission line theory.
Instead, they are concerned with the following question: given
a line length of x feet and a data rate of n bps, does the system
work-and if so-what amount of transition jitter is
expected? To answer this question using analytical methods is
quite difficult because evaluation of the expressions representing the line voltage or current as a function of position and
time is an involved process. The references at the end of this
section provide a starting point to generate and evaluate
analytical expressions for a given cable.

The effects on the LRCG line parameters, the variations in
ZO' a (wI, and propagation velocity as a function of applied
frequency are discussed later in this section. Using an empirical approach to answer the "how far- how fast" question
involves only easily made laboratory measurements on that
selected cable. This empirical approach, using the binary eye
pattern as the primary measurement tool, enables the construction of a graph showing the line length/data rate/signal
quality trade -offs for a particular cable. The terms describing
signal quality are discussed later in this section. The technique of using actual measurements from cables rather than
theoretical predictions is not as subject to error as the
analytical approach. The only difficulties in the empirical
method are the requirements for a high quality, real time (or
random sampling) oscilloscope and, of course, the requisite
amount of transmission line to be tested.

The following sections discuss the origins of the second-order
effects-skin effect, proximity effect, radiation loss effect,
and dielectric loss effect-and their influence on the LRCG
transmission line parameters.

Also discussed in this chapter are commonly used pulse
codes and ways to estimate coaxial cable signal quality in lieu
of eye pattern measurements.

Skin Effect This phenomenon is based on two facts: a
current flow in any real conductor produces an electric
field given by Ohm's Law; the current distribution and/

current density redistribution reduces the effective crosssectional area of the conductor, thereby increasing the perunit-length line resistance. This effect is a function of the
conductor diameters, the separation of the conductors
from each other, and frequency. The analytical evaluation
of the proximity effect is quite complicated and except for
certain limited cases (see Arnold" and Dwight12), no general rule of thumb expressions have been proposed. The
proximity effect is not present in coaxial cables because of
their circular symmetry. The proximity effect is a significant contributor to signal losses particularly in cases of a
twisted pair or parallel wire lines.

or magnetic field distribution in a conductor is frequency
depe.ndent. For dc current in a single isolated conductor,
the current density is uniform across the conductor. When
alternating current is used, the current density is not
uniform across the conductor. Instead, the current tends
to concentrate on the conductor surface. Current density
continuously increases from the conductor center to its
surface, but for practical purposes, the current penetration
depth, d, is assumed as a dividing line for current density.
The current is assumed to flow in a imaginary cylinder of
thickness d with a constant current density throughout
the cylinder thickness. Distribution of current densities
for both actual and assumed models is shown in Figure 4-1.

Both twisted pair and parallel wire lines exhibit radiation
losses and these losses contribute to the effective per-unitlength line resistance. Radiation loss is dependent to a
large extent on the characteristics of the materials close
to the line; so radiation loss is quite difficult to' calculate,
but can be measured if necessary.

in which case, d would be the penetration depth expressed
in meters.
Because the skin effect reduces the equivalent conductor
cross-sectional area, increasing frequencies cause an increase in the effective resistance per unit length of the line.
This in turn leads to signal attenuation increasing with
frequency. If the frequency response of a cable is plotted
on log-log graph paper, log dB, or Nepers vs log frequency,
the curve slope will be 0.5 if the cable losses are primarily governed by classical skin effects. The slope of the
attenuation curve,. along with the attenuation at a particular frequency, can be used to estimate coaxial cable transient response as a function of length},'

Dielectric Loss Effect: Dielectric losses result from leakage
currents through the dielectric material. This causes an
increase in the shunt conductance per unit length and
produces signal attenuation. Fortunately, for most dielectric materials in common use, this loss is very small
particularly for frequencies below 250 MHz. For most
practical purposes, then, dielectric losses may be neglected as they are usually overshadowed by skin effect losses.

Proximity Effect: This is a current density redistribution in

Radiation Loss: Radiation losses cause an apparent rise
in resistance per unit length increasing with frequency.
The mechanism of radiation loss is energy dissipation
either as heat or magnetization via eddy currents in nearby
metallic or magnetic masses, with the eddy currents in·
duced by line currents. Coaxial cables do not exhibit this
effect because the signal magnetic field is confined between the shield and the outside of the center conductor.
Ideally, the magnetic field produced by shield current cancels the field produced by current in the center conductor
(for points outside the shield).

For example, the sink decoder may extract the clock rate from
the data or perhaps detect and correct errors in the data. From
the optional sink decoder, the recovered binary data passes to
the information sink-the destination for the information
source data.

ing task is to ensure that a particular bit arriving at its destination is interpreted in the proper context. To achieve this,
both the sender and receiver of the data must accomplish the
five following requirements.
1.

Agree upon the nominal rate of transmission; or how
many bits are to be emitted per second by the sender.

2.

Agree upon a specified information code providing a oneto-one mapping ratio of information-to-bit pattern and
vice versa.

3.

Establish a particular scheme whereby each bit can be
properly positioned within a byte by the receiver of the
data (assuming that bit-serial transmission is used).

4.

Define the protocol (handshaking) sequences necessary
to ensure an orderly flow of information.

5.

Agree to the electrical states representing the logic values of each bit and the particular pulse code to be used.

Assume for the moment that the source encoder and sink decoder are "transparent"; that is, they will not modify the
binary data presented to them in any way. Line driver signals, then, have the same tim ing as the original bit stream.
The data source emits a new bit every tB seconds. The pulse
code produced by the source encoder and line driver is called
Non-Return to Zero (NRZ), a very common signal in TTL logic
systems. A sample bit pattern with its NRZ representation is
shown in Figure 4-7a. The arrows at the top represent the
ideal instants, or the times the signal can change state. The
term unit interval is used to express the time duration of the
shortest signaling element. The shortest signaling element
for NRZ data is one bit time IB' so the unit interval for NRZ
data is also tB. The rate at which the signal changes is the
modulation rate (or signaling speed), and baud is the unit of
modulation rate. A modulation rate of one baud corresponds
to the transmission of one unit interval per second. Thus the
modulation rate, in baud, is just the reciprocal of the time for
one unit interval. A unit interval of 20 ms, therefore, means
the signaling speed is 50 baud. The reason for differentiating
between the information rate in bits per second (bps) and the
modulation rate in baud will be clarified after examining
some of the other pulse codes later in this chapter.

These are by no means all of the points that must be agreed
upon by sender and receiver-but these are probably the most
important. Items 2, 3 and 4 are more or less "software" type
decisions, because the actual signal flow along the transm ission line is usually independent of these decisions. Because
items 1 and 5 are much more dependent on the characteristics of line drivers, line receivers, and transmission lines, they
are the primary concern here.
Figure 4-6 represents the components of a typical data transmission system. The information source can be a computer
terminal or a digitized transducer outout, or any device emitting a stream of bits at the rate of one bit every tB seconds.
This establishes the information rate of the system at 1/tB
bits per second. The information source in the figure feeds a
source encoder which performs logic operations not only on
the data, but also on the associated clock and, perhaps, the
past data bits. Thus, the source encoder produces a binary
data stream controlling the line driver. The line driver interfaces the source internal logic levels (TTL, MOS, etc.) with
transmission line current/voltage requirements. The transmission line conveys signals produced by the line driver to the
line receiver. The line receiver makes a decision on the signal
logic state by comparing the received signal to a decision
threshold level, and the sink decoder performs logic opera-

Fig. 4-6.

NRZ data should always be accompanied by a clock signal,
Figure 4-7b, which tells the receiver when to sample the data
signal and thus determine the current logic state. For the example in Figure 4-7b, the falling edge of the clock corresponds to the middle of the data bits, so it could be used to
transfer the line receiver data output into a binary latch. The
falling edge of the clock is thus the sampling instant for the
data. The line receiver does have a decision threshold or
slicing point so that voltages above that threshold level produce one logic state output, while voltages below the threshold produce the other logic state at the receiver output. The
receiver may incorporate positive feedback to produce hysteresis in its transfer function. This reduces the possibility of
oscillation in response to slow rise or fall time signals applied
to the receiver inputs.

val. A 25% isochronous distortion means that the peak-topeak time jitter of the transition is .25 unit interval (max).

Previously in this chapter, it was stated that the fast rise and
fall times of signals, corresponding to the transitions between
data bits, are rounded out and slowed down by a real transmission line. Each transition of the signal applied to the line
by the line driver is transformed to a rounded out transition
by the dispersion and attenuation of the transmission line.
The resultant signal at the load end of the line consists of the
superposition of these transformed transitions. The waves
arriving at the load end of the line are shown in Figure 4-7c
and their superposition is shown in Figure 4-7d. It is assumed
that the line is terminated in its characteristic resistance so
that reflections are not present. The receiver threshold level
is shown here, superimposed on the resultant load signal, and
the re-converted data output of the line receiver is shown in
Figure 4-7e along with the ideal instants for the data transitions (tick marks).

Another type of received-signal time distortion can occur if
the decision threshold point is misplaced from its optimum
value. If the receiver threshold is shifted up toward the One
signal level, then the time duration of the One bits shortens
with respect to the duration of the Zero bits, and vice versa.
This is called bias distortion in telegraphy and can be due to
receiver threshold offset (bias) and/or asymmetrical output
levels of the driver. This effects is shown in Figure 4-8.
Bias distortion and characteristic distortion (intersymbol
interference) together are called systemic distortion, because
their magnitudes are determined by characteristics within the
data transmission system. Another variety of time distortion
is called fortuitous distortion and is due to factors outside the
data transmission system such as noise and crosstalk, which
may occur randomly with respect to the signal timing.

Comparing the original data (Figure 4-7a) to the recovered
data (Figure 4-7e) shows that the actual recovered data transitions may be displaced from their ideal instants (tic marks
on Figure 4-7e). This time displacement of the transitions
is due to a new wave arriving at the receiver site before the
previous wave has reached its final value. Since the wave
representing a previous data bit is interfering with the wave
representing the present data bit, this phenomenon is called
intersymbol interference (in telegraphy it is called characteristic distortion). The intersymbol interference can be red'uced
to zero by making the unit interval of the data signal quite
long in comparison to the rise/fall time of the signal at the
receiver site. This can be accomplished by either reducing
the modulation rate for a given line length, or by reducing
the line length for a given modulation rate.

SIGNAL QUALITY MEASUREMENT-THE EYE PATIERN
To examine the relative effects of intersymbol interference on random NRZ data and a "dotting"* pattern, see
Figure 4-9. The top two waveforms represent the NRZ data
and dotting pattern as outputs into two identical long transmission lines. The middle two traces illustrate the resultant
signals at the line outputs and the bottom two traces show
the data output of the line receivers. The respective thresholds are shown as dotted lines on the middle two traces. The
arrows indicate the ideal instants for both data and dotting
signals.
Notice that the dotting signal (0) is symmetrical, i.e.. every
One is preceded by a Zero and vice versa, while the NRZ data
is random. The resultant dotting signal out of the line is also
symmetrical. Because, in this case, the dotting half-cycle
time is less than the rise/fall time of the line, the resultant
signal out of the line (E) is a partial response-it never reach-

Signal quality is concerned with the variance between the
ideal instants of the original data signal and the actual transition times for the recovered data signal.
For synchronous signaling, such as NRZ data, the isochronous
distortion of the recovered data is the ratio of the unit interval to the maximum measured difference irrespective of sign
between the actual and theoretical significant instants. The
isochronous distortion is, then, the peak-to-peak time jitter
of the data signal expressed as a percentage of the unit inter-

*The term dotting pattern is from telegraphy and means an alternating sequence of 1·bits and a·bits (the "dot dot dot" etc.). Note that an NRZ dotting
pattern generates a signal which has a 50% duty cycle and a frequency of
112 tB (Hz).

Comparison of NRZ Random Data and "Dotting" Signals

es its final level before changing. The dotting signal, due to
its symmetry, does not show intersymbol interference in the
same way that a random NRZ signal does. The intersymbol
interference in the dotting signal shows up as a uniform displacement of the transitions as shown in Figure 4-9f. The
NRZ data shows intersymbol interference, in its worst light,
due to its unpredictable bit sequence. Thus, whenever feasibility of a data transm iss ion system is to be tested, a random
data sequence should be used. This is because a symmetri-

cal dotting pattern or clock signal cannot always show the
ef·fects of possible intersymbol interference.
A very effective method of measuring time distortion through
a data transmission system is based on the eye pattern. The
eye pattern, displayed on an oscilloscope, is simply the
superposition-over one unit interval-of all the Zero-to-One
and One-to-Zero transitions, each preceded and followed by
various combinations of One and Zero, and also constant One
10-34

and Zero levels. The name eye pattern comes from the resemblance of the open pattern center to an eye. The diagramatic
construction of an eye pattern is shown in Figure 4-10. The
data sequence can be generated by a pseudo-random sequence generator (PRSG), which is a digital shift register
with feedback connected to produce a maximum length sequence. The PRSG, requiring only two devices (Figure 4-11),
generates a sequence that repeats after 22°_1 bits. Feedback

connections for PRSG shift registers from 4 to 20 bits in length
are shown in Figure 4-12.
Severa I featu res of the eye pattern make it a usefu I tool for
measuring data signal quality. Figure 4-13 shows a typical
binary eye pattern for NRZ data. The spread of traces crossing the receiver threshold level (dotted line) is a direct measure of the peak-to-peak tmnsition jitter---isochronolls distilr-

tion in a synchronous system-of the data signal. The rise and
fall time of the signal can be conveniently measured by using
the built-in 0% and 100% references produced by long strings
of Zeros and Ones. The height of the trace above or below the
receiver threshold level at the sampling instant is the noise
margin of the system. If no clear transition-free space in the
eye pattern exists, the eye is closed. This indicates that errorfree data transm iss ion is not possible at that data rate and
line length with that particular transmission line without resorting to equalizing techniques. In some extreme cases,
error-free data recovery may not be possible even when using
equalizing techniques.

By using the eye pattern to measure signal quality at the load
end of a given line, a grapl'\ can be constructed showing the
tradeoffs in signal quality-peak-to-peak jitter-as a function
of line length and modulation rate for a specific pulse code.
An example graph for NRZ data is shown in Figure 4-15. The
graph was constructed using eye pattern measurements on a
24 AWG twisted pair line (PVC insulation) driven by a differential voltage source driver (9614) with the line parallelterminated in its characteristic resistance (96 ,0.). The oscilloscope photographs in Figure 4-16 show the typical eye patterns for NRZ data with various amounts of isochronous
distortion. The straight lines represent a "best fit" to the
actual measurement points. Since the twisted pair line used
was not specifically constructed for pulse service, the graph

The eye pattern can also be used to find the characteristic

probably represents a reasonably good worst·case condition
insofar as signal quality vs line length is concerned. Twisted
pair lines with polyethylene or Teflon® insulation have shown
better performance at a given length than the polyvinyl chloride insulation. Likewise. larger conductors (20 AWG, 22
AWG) also provide better performance at a given length.
Thus. the graph in Figure 4·15 can be used to estimate feasi·
bility of a data transmission system when the actual cable to
be used is unavailable for measurement purposes. The
arbitrary cutoff of 4000 feet on the graph was due to an observed signal amplitude loss of 6 dBV (112 voltage) of the
24 AWG line at that distance. The cutoff of 10 Mbaud is

based on the propagation delays of the typical TIL line drivers
and receivers. Field experience has shown that twisted pair
transmission systems using TIL drivers and receivers have
operated essentially error-free when the line length and modulation rate are kept to within the shaded recommended
operating region shown in Figure 4-15. This has not preclud·
ed operation outisde this region for some systems. but these
systems must be carefully designed with particular attention
paid to defining the required characteristics of the line. the
driver. and the receiver devices. The use of coaxial cable
instead of twisted pair lines almost always yields better per·
formance. i.e., greater modulation rate at a given line length

and signal quality. This is because most coaxial cable has a
wider bandwidth and reduced attenuation at a given length
than twisted pair line (one notable exception is RG 174/U
cable). In the next section, a method is discussed that allows
a rough estimation of the maximum "safe" modulation rate
for a given length of a particular coaxial cable when actual
eye pattern measurements cannot be made on that cable.

In many design situations it is not always convenient to measure signal quality using the eye pattern. This can be caused
by lack of equipment, time, or unavailability of the transmission line to perform the necessary measurements. In such
cases, the following rule of thumb applies: the unit interval
should be greater than twice the 10 to 90% rise or fall time
of the line, i.e.,

It should be remembered that, in some ways, the eye pattern
gives the minimum peak-to-peak transition jitter for a given
line length, type, pulse code, and modulation rate. This is
because the eye pattern transition spread is the result of intersymbol interference and reflection effects (if present) and
this minimum jitter is only obtainable if the following conditions are met.
•

The One and Zero signal levels produced by the line driver
are symmetrical, and the line receiver's decision threshold
(for NRZ signaling) is set to coincide with the mean of those
two levels.

•

The line is perfectly terminated in its characteristic resistance to prevent reflections from altering the signal threshold crossings.

•

The time delays through driver and receiver devices for
both logic states is symmetrical and there is no relative
skew in the delays (difference between L --+ Hand H --+ L
propagation delays =0). This is especially important when
the device propagation delays become significant fractions
of the unit interval for the applicable modulation rate.

tui ~ 2t 10 _90 %
Eye patterns that meet this criterion show that adherence to
this rule will keep the peak-to-peak jitter to less than 5% of
the unit interval. If the 10% to 90% rise time cannot be easily
measured-as is the case with coaxial cables whosedom inant
loss mechanism is simple skin effect-then the 10 to 80%
rise time may be used instead of the 10 to 90% rise time.
The corresponding peak-to-peak jitter, due to intersymbol
interference with the tui ~2 tlO-80% rule, is usually less
than 10%. In any event, if the unit interval is less than the 0
to 50% rise time of the signal at the line end (tui
to-50%),
then the error-free recovery of NRZ data is not possible without using equalizing techniques. Sometimes, changing to a
pulse code which allows partial response recovery will enable
data transmission at an otherwise unusable line length-speed
combination. When actual eye pattern measurements cannot
be made, an estimate of feasibility can still be obtained by calculating the signal transition time.

<

N.S. Nahman 2 ,4 presented a simple method to predict the
transient response of a coaxial cable from the cable attenuation. The procedure was based on a graphical analysis technique allowing prediction of the step response of a network
from a graph of the imaginary part of the transfer function,
in this case the imaginary part of 'Y (s). The normalized step
responses (Figure 4-18) are plotted with the abscissa in normalized time (x)

If anyone of these conditions is not satisfied, the signal quality is reduced (more distortion). The effects of receiver bias
or threshold ambiguity and driver offset can be determined
by location of the decision threshold(s) on the oscillograph of
the eye pattern for that driver/cable modulation rate combination. For eye patterns displaying more than 20% isochronous distortion, the slope of the signal in the transition
region is relatively small. Therefore, a small amount of bias
results in a large increase in net isochronous distortion. See
Figure 4-17 for a graphic illustration of this effect. In the
interest of conservative design practices, systems should always be designed with less than 5% transition spread in the
eye pattern. This allows the detrimental effects due to bias to
be minimized, thus simplifying construction of line drivers
and receivers.

immunity to noise relative to a binary system. This is because

If the desired modulation rate is 1 Mbaud (tui = 1.0 fJs) and
the line length is 1000 feet, then the system using RG59/U
cable would probably operate satisfactorily. Be aware, however, that if the single slope (m) does not accurately approximate the actual attenuation characteristic of the coaxial
cable, then Nahman's method will show considerable error in
predicting the signal transition time. RG174/U is a coaxial
cable with an attenuation characteristic that has a slope in
the 0.3 to 0.65 range depending on the frequency. Thus the
method cannot be accurately applied to RG174/U cable.

In general, the binary class of pulse codes can be grouped
into four categories;

Also, Nahman's method cannot be applied to commonly available twisted pair or parallel wire lines. This is because knowledge of either the I ine attenuation or its phase characteristics
is not normally sufficient to completely specify the transfer
function. Thus, the previously mentioned Bode condition is
not satisified, and the analysis previously used cannot be applied satisfactorily.

state, and the other signal level corresponding to the opposite
logic state. In NRZ-M or NRZ-S signaling, however, a change
in signal level at the start of a bit interval corresponds to one
logic state and no change in signal level at the start of a bit
interval corresponds to the opposite logic state. For NRZ-M
pulse codes, a change in signal level at the start of the bit
interval indicates a logic One (Mark), while no change in signal level indicates a logic Zero (Space). NRZ-S is a logical
complement to NRZ-M. A change in signal level means a logic
Zero and no change means logic One. With NRZ-M and NRZ-S
pulse codes, therefore, there is no direct correspondence
between signal levels and logic states as there is with NRZ-L
signaling. Any of the NRZ pulse codes may, of course, be
used in unipolar or polar form. The NRZ codes are shown in
Figure 4-20, along with their generation algorithms*, signal
levels vs time, and their general power density spectrum.

A secondary differentiation among the pulse codes is concerned with the algebraic signs of the signal levels. If the
signal levels have the same algebraic sign for their voltages
(or currents) and differ only in their magnitudes, the signaling is called unipolar. A very common example of unipolar
signaling is TIL or ECL logic. TIL uses two positive voltages
to represent its logic states, while ECL uses two negative
voltages for its logic states. The complement of unipolar
signaling is polar signaling. Here, one logic state is represented by a signal voltage or current having a positive sign
and the other logic state is represented by a signal with a
negative sign. For binary signals, the magnitude of both signals should be equal, ideally. Their only difference should be
in the algebraic signs. This allows the receiver to use ground
as its decision threshold reference.

The degradation in signal quality caused by intersymbol interference for NRZ-L signaling was discussed earlier. Since
the minimum signaling element (unit interval) for all three
NRZ pulse codes is equal to tB' the previous signal quality
discussion for NRZ-L also applies equally to NRZ-M and
NRZ-S pulse codes. The following is a capsule summary ofthe
previous discussion on NRZ signal quality.

Non-Return to Zero (NRZ) Pulse Codes
There are three NRZ pulse codes: NRZ - Level (NRZ-L), NRZMark (NRZ-M), and NRZ - Space (NRZ-S). NRZ-L is the same
pulse code as previously discussed. In NRZ-L signaling, data
is represented by a constant signal level during the bit time
interval. with one signal level corresponding to one logic

Non-Return to Zero (NRZ) Pulse Codes

10-41

II

•

When ts is less than the 0-50% rise or fall time of the signal at the line end, the open space in the eye pattern closes,
thereby indicating error-free data transmission is unlikely.

•

When ts is less than the 10-90% rise or fall time of the
line end signal, some intersymbol interference is present
and thus, some time jitter in the transitions of the recovered data will be present.

(PPM) uses a pulse of ts/4 duration beginning at the start of
the bit interval to indicate a logic Zero, and a ts/4 pulse beginning at the middle of the bit interval to indicate a logic
One. Pulse Duration Modulation (PDM) uses a ts/3 duration
pulse for a logic Zero and a (2/3) ts pulse for a logic One, with
the rising edge of both pulses coinciding with the start of the
bit interval. PDM with tS/4 pulse widths is also used but better results are usually obtained with the ts/3, 2 ts/3 scheme.

NRZ codes are simple to generate and decode because no
precoding or special treatment is required. This simplicity
makes them probably the most widely used pulse codes, with
NRZ-L the leader by far. NRZ-M has been widely used in
digital magnetic recording where it is usually called NRZI
for Non-Return to Zero, Invert-on-Ones. In terms of the four
desirable features for a pulse code listed at the start of this
section, however, none of the NRZ codes are all that greatNRZ codes do possess a strong dc component, and have
neither intrinsic clocking, nor error detection features. Even
so, their power frequency spectra are used as references for
comparison with other pulse codes.

The reason for differentiating between information rate and
modulation rate can now be further clarified. Each of the RZ
pulse codes in Figure 4-21 has the same information rate;
ie., lIts bits per second. Their respective minimum signaling elements (unit intervals) however, are all less than ts
so the modulation rate for the RZ pulse code is greater than
the information rate. Remember that with NRZ signaling,
the unit interval and the bit time interval are equal in duration, so the information rate in bps is equal to the modulation rate in bauds. For isochronous NRZ signaling, the
measures bps and baud are both synonymous and interchangeable.

Return to Zero (RZ) Pulse Codes
The RZ group of pulse codes are usually simple combinations
of NRZL data and its associated single or double frequency
clock. Sy combining the clock with data, all RZ codes possess
some intrinsic synchronization feature. Three representative
RZ pulse codes are shown in Figure 4-21. Unipolar RZ is
formed by performing a logic AND between the NRZ-L data
and its clock. Thus a logic Zero is represented by the absence
of a pulse during the bit time interval, and a logic One is represented by a pulse as shown. Pulse Position Modulation

Inspection of unipolar RZ signaling reveals that the unit interval is 1/2 bit interval (tui = tS/2). When this unit interval
is less than the 0-50% rise or fall time of the line, the data is
likely to be unrecoverable. With a fixed modulation rate, the
price paid to include clocking information into unipolar RZ is
reduced information rate over that for NRZ signaling. Likewise, for PPM with its unit interval of tS/4, the information
rate reduces to 114 that of NRZ data under the same conditions. This is because the maximum modulation rate is determined by the 50% rise time of the line which is constant

for a given length and type of line. PDM has a unit interval of
t8/3 so, for a given maximum modulation rate, the resulting
information rate is 113 that of NRZ data.

change indicates a logic Zero. For Bi 4> -5, no signal level
change in the middle of the bit interval means a logic One,
while a change means a logic Zero.

The preceding argument should not be taken as strictly correct-since the actual intersymbol interference patterns for
the three RZ codes discussed differ somewhat from the pattern with NRZ codes. A random sequence of NRZ data can
easily consist of a long sequence of Zeros followed by a single
One and then a long sequence of Zeros, so the t50% limit can
be accurately applied. Unipolar RZ, in response to the same
long data sequence, produces a t8/2 pulse, so the t50%
argument can be applied here too. With PPM and PDM, the
maximum time that the line signal can be in one state is quite
reduced from the NRZ case. For PPM, this time is 1.25 tB
(010 data sequence) while for PDM, it is .67 tB (see Figure
4-21). With PPM and PDM, then, the line signal may never
reach the final signal levels that it does with NRZ data. So,
the PPM and PDM signals have a head start, so to speak, in
reaching the threshold crossing of the receiver. Because of
the reduced time that PDM and PPM signal levels are allowed
to remain at one signal level, their signaling may still operate
at a modulation rate Slightly above that where the NRZ data
shows 100% transition jitter. Even with this slight correction
to the previous discussion, the RZ group of pulse codes still
sacrifice information rate in return for synchronization. The
PPM scheme appears to be a poor trade in this respect, since
PDM allows a greater information rate while retaining the
self-clocking feature. Unipolar RZ, because it provides no
clocking for a logic Zero signal, is not generally as useful as
PDM for baseband data transmission. However, unipolar RZ
is used in older digital magnetic tape recorders.

In Bi ¢ -L (also called Manchester Code), a positive-going
transition at the middle of the bit interval means a logic Zero,
while a negative-going transition there indicates a logic One.
The fourth member of the PE family is Delay Modulation
(DM)15.'6 sometimes referred to as Miller code. Here logic One
is represented by a mid-bit interval signal level change, and a
logic Zero is represented by a signal level change at the end of
the bit interval if the logic Zero is followed by another logic
Zero. If the logiC Zero is immediately followed by a logic One,
no signal level transition at the end of the first bit interval is
used. The waveforms encoding algorithms, and general
power density spectra for the PE pulse code family are shown
in Figure 4-22.
A brief inspection of the signal waveforms for the three Biphase pulse codes reveals that their minimum signaling element has a duration of one-half bit interval (tui = tB/2); the
longest duration of either signal level is one bit interval.
Similarly, DM is seen to have a minimum signaling element
of one bit interval (tui = tB) and the maximum duration of
either signal level is two bit intervals (produced by a 101 pattern). Biphase codes should exhibit eye closure (they would
not be recoverable without equalization) when tui
to-50%'
So, a 50% jitter on NRZ signaling approximately corresponds
to the Biphase codes non-operation point. Biphase codes,
therefore, provide one-half the information rate of NRZ signals at a given maximum modulation rate. This is in exchange
for synchronization information and a dc-free spectrum when
used in polar form.

:s

Examination of RZ codes shows only one more desirable
feature than NRZ codes: clocking. RZ codes still have a dc
component in their power density spectrum (Figure 4-21)
and their bandwidth is extended (first null at 2/tB) over that
of NRZ (first null 1/tB)' RZ codes do not have any intrinsic
error detection features.

DM should have essentially the same intersymbol interference
characteristics as NRZ, since the unit interval is the same for
both codes. DM may perform slightly better than NRZ, because the maximum duration of either signal level is two bit
intervals. Overall, DM is better coding scheme than the Bi ¢.
It does not require as much bandwidth as Bi cp and still possesses the desirable dc response and synchronization qualities.

Phase Encoded (PE) Pulse Codes
The PE group of pulse codes uses signal level transitions to
carry both binary data and synchronization information. Each
of the codes provides at least one signal level transition per
bit interval aiding synchronous recovery of the binary data.
Simply stated, Biphase-Level (Bi ¢ -L) code is binary phase
shift keying (PSK) and is the result of an Exclusive-OR logic
function performed on the NRZ-L data and its clock; it is further required that the resultant signal be phase coherent
(i.e., no glitches). Biphase-Mark (Bi ¢ -M) and Biphase-Space
(Bi ¢ -5) codes are essentially phase coherent, binary frequency shift keying (FSK). In Bi ¢-M, a logic One is represented
by a constant level during the bit interval (one-half cycle of the
lower frequency 1/(2 tB)' while a logic Zero is represented by
one-half cycle of the higher frequency 1/tB' In Bi ¢-S, the
logic states are reversed from those in Bi¢ -M. Another way of
thinking of Bi4> -M or Bi 4> -5 is as follows.
•

•

Both Bi ¢ and DM are good choices for digital magnetic
recording'6; Bi ¢ is widely used in disc memory equipment,
and DM is rapidly gaining acceptance where high bit packing
densities are desired. Overall scoring, in terms of the four
desirable characteristics, shows the PE pulse codes with three
primary features; bandwidth compression, no dc, and intrinsic
synchronization.
The Bi ¢ family does not possess any intrinsic error detection
scheme. DM does possess the capability of detecting somebut not all-single bit errors. This detection process is accomplished by checking to see if a single level persists longer
than two bit intervals, in which case, an error is indicated.
DM detection requires two samples per bit interval.

Change Signal level at the end of each bit interval regardless of the logic state of the data.

Multi-Level Binary (MLB) Pulse Codes
The pulse codes in the MLB group discussed have a common
characteristic of using three signal levels (expressed in shorthand notation as +, 0, -) to represent the binary information,
but each receiver decision yields only one bit of information.
These are sometimes called pseudoternary codes to distinquish them from true ternary codes wherein each receiver
decision can yield 1.58 information bits.

Change signal level at the middle of each bit interval to
mean a particular logic state.

In Bi ¢ -M (sometimes called diphase), a mid-bit interval
change in signal level indicates a logic One (Mark), while no

full-duplex operation using frequency division multiplexing
(FDM) techniques is widely used. The most common example
of the FDM full-duplex operation, the 103 type modem, uses
frequency shift keying (FSK) and two frequency bands to
keep the data paths separate.

Full-Duplex operation is simultaneous, two-way data flow
between two ports. It is not usually feasible in baseband signalling, although some bridge-type circuitry has been used'
The difficulty in baseband full-duplex operation is the separation of the signal levels produced by the two drivers operating on the loop simultaneously. However, non-baseband,

The logical extension to half-duplex operation is mUltiplex
sometimes called a data bus or party line (Figure 5-6). Multiplex operation is non-simultaneous data flow among three or
more ports connected to the same physical transmission line.
Like simplex and half-duplex modes, multiplex operation
may be used in single-ended or differential form with polar
or unipolar drivers.

Multiplex (Data Bus) Operation

The primary advantage of multiplex operation over simplex
operation is reduction of wire costs-one physical transmission line can serve where several were once required.
The disadvantages of multiplex mode include increased complexity of driver circuits to include an "off" state, and the
added logic required to implement bus protocol or "handshaking".

5) Transmitting port receives the acknowledgement, and
releases control of the bus so that other ports may
pass their data.
The overall bus operation is either polled or asynchronous.
In polled operation, a central bus controller addresses each
port in turn to ask if any data is waiting to be sent. If the addressed port has no traffic, it signals no data and the controller inquires at the next port. If the port has some data, then
the controller gives a go ahead to the port; data is sent, and
the controller then inquires at the next port.

Particularly, when multiplex operation is desired, consideration must be given to the following areas:
•

The protocol or handshaking required for a particular port
on the bus to send data must be designed. The protocol
sequence usually involves the following operations.

In asynchronous operation, any port having data essentially
"holds up its hand" and waits for a go-ahead signal to ripple
down the series enabling logic. The priority for a particular
port is determined by the ports proximity to the master control port which sends a go-ahead down the enable logic chain
at regular time intervals. This scheme is well suited to busorganized minicomputers. The Digital Equipment Corporation's Unibus® and Omnibus® architectures are excellent
examples.

1) The port must signal a desire to use the bus (interrupt).
2) Bus controller must acknowledge interrupt and send
go ahead command.
3) Port assumes control of bus and sends data, perhaps
preceded by the code to indicate the recipients(s) of
the following data.

•

4) Receiving portIs) must acknowledge receipt of data.
10-52

The effect of powered-down drivers and receivers on normal bus operation must also be considered. Integrated
circuit drivers and receivers contain paraSitic diodes that

port per unit time, are known 7 •

are normally reverse biased when the power supply is on.
Unless special design techniques are used, these diodes
can become forward-biased when the unit is powereddown causing the bus to malfunction.

STANDARDIZED INTERFACES
There are two main ways the interface electrical characteristics become standardized. The first, and probably most
common, is informal adoption via proliferation of devices
Excellent
having the specified electrical characteristics.
examples of this informal method are provided by TTL and
ECl logic levels, and loading rules. The input/output electrical characteristics of these two logic families have become
"standards" because many different manufacturers make
devices which can be easily interconnected.

• The protocol timing must include sufficient time delays
to allow for the different port-to-port signal propagation
delays.
•

Both physical ends of the transmission line comprising a
channel for the bus must be terminated to prevent spurious
signal levels due to reflections.

•

Stubs or taps from the main transmission line should be
kept to a minimum length. A daisy chain wiring method is
preferable to a tap-off method. If stubs must be used,
then to cause the least perturbations on the line, the stub
length should be controlled such that the propagation delay of the stub is less than 1/8 of the Signal rise or fall
time at the stub-to-line connection point.

•

Informal standards may also be born when an equipment
manufacturer announces a product that other competing
manufacturers wish to directly connect to their respective
products. If the original manufacturer of the product has a
large share of the market place (and a large number of competitors) an "instant standard" can eaSily arise. A good example of this is the IBM 360/370 I/O interface (channel to
control unit)', which is standardized primarily because, first,
IBM has a large share of the computer market place; and
second, a large number of manufacturers are interested in
selling "plug compatible" peripheral devices. Thus, one
company's electrical interface may become an informal standard in a very short time. Likewise, minicomputer manufacturers, such as DEC, may have their in-house interface
characteristics for their Unibus® and Omnibus® "standardized" via the wide application of their products, and the proliferation of competitive add-on manufacturers.

If a 3-state driver system is used (logic Zero, logic One
and off or driver in high impedance state), some means
must be provided to detect the difference between a driver
sending data and the all-drivers-off condition. In the 2state bus system, this problem does not occur because a
logic Zero (usually a HIGH) indicates either a logic Zero
or that no port is currently sending. A logic One (usually
a lOW) on a 2-state system then indicates a port is transmitting a logic One and the receiver should interpret it as
such.

Formal interface standards are usually issued either by collective associations of manufacturers (EIA), U.S. Government
and military (FIPS, DCA), international organizations (CCITT,
ISO), or other interested organizations (IEEE, ANSI). These
standards usually arise when two different pieces of equipment that may be built by two or more different manufacturers must interface, as in data terminals and data modems,
or when a government organization is setting up a system
which requires interface uniformity. Adherence to the standards is usually voluntary.
However, if a manufacturer
wishes to sell products in the application area encompassed
by the standard, it behooves him to comply if at all feasible.
In the past, formal standards have usually adopted the electrical characteristics of a pre-existing interface, especially if
the usage of such electrical characteristics was widespread
at the time the standard was drafted. The resultant standard
is then mostly a blessing given to one set of interface specifications, rather than an optimal, more general solution to
data communications interface problems. lately, both the
national and international standards organizations have been
seeking greater intercourse with one another, with an effort
to produce fewer different electrical interface standards, and
ascertain the optimum technical solution to satisfy the greatest number of application requirements. Interoperability and
compatibility with pre-existing equipment is a primary requirement in any new standard, consequently much work is
devoted to this task.

• The data format must also be considered:
Parallel operation is fast but expensive, since it requires
one transmission line and the associated interface for
every bit of the word (or byte) transmitted in parallel.
Serial operation is slower, but requires only one transmission line and interface per port. This saving may, however,
be partially offset by the need for a parallel-to-serial converter at the transmitting site, and a serial-to-parallel
converter at the receivi ng site.
The parallel structure is commonly used for rapid exchange
of data over short distances; e.g., within a computer or
between a computer and peripherals. The serial structure
is used for communications over long distances, as between
a terminal and its controller.
•

A final consideration concerns polled operation of a
multiplex system. The amount of time necessary to address and receive acknowledgement from a port must be
weighed against the volume of data the ports normally
send, and the total number of ports on the bus. If there is
a large number of ports on the bus, most of the time
might be used by the polling operation with very little
time devoted to actual exchange of information. A large
number of ports combined with a high relative volume of
traffic expected per port can lead to data backing up at
each port waiting to be sent, and an overall reduction in
information throughout. In a real time system where fast
response is essential, serious consideration should be given
to splitting up a single large bus into several satellite
busses, each with its own polling controller and protocol
with respect to the central bus. Queuing theory can be
used to estimate the throughput on a bus structure when
many variables, including the number of ports, the mean

The majority of requests for standardized interface devices
are currently for EIA RS232-C (and CCITT V.24), Mil-STDl88C (low level), and IBM 360/370 I/O. The EIA interface3
and CCITT V.244 are intended for use between data terminal
equipment (DTE) and data communications equipment (DCE).
The two standards have essentially the same electrical specifications, but differ in Signal lead nomenclature. Both standards also specify the protocol to be used between the DTE

need for an external capacitor for each driver. Second, the
logic function performed by the 9616 is AND-OR-INVERT
(AOI), instead of the usual NAND structure. The AOI still allows the "SPACE-~Ring" of two data signals as provided by
the NAND type drivers, while activation of the NOR (Inhibit)
input to the 9616 forces the driver to a MARK state (called
MARK Hold) regardless of the logic states of the data inputs.
The latter feature of the 9616 enables the protocol sequence
to easily be initiated or terminated without requiring the
extra logic gate needed by NAND type drivers performing the
same function. More discussion on EIA RS232-C and the
9616/9617 devices is presented in Fairchild Application
Note 320. The usage of the 9616/9617 devices as an RS232C interface is shown in Figure 5-8.

and DCE. The interface is a simplex, single-ended, polar,
unterminated type with line length and slew rate limiting
used for control of reflection effects. The implied maximum
cable length is 50 feet, and all signals are referenced to a
common signal return lead. The maximum modulation rate
on the interface is 20 kbaud. The primary electrical characteristics of the interfaces are listed in Figure 5-7.
Fairchild manufactures one triple driver (9616) and two receivers (9617 and 9627) to meet the requirements for this
application. The 9616 triple EIA/MIL line driver has two
particularly valuable features making it easier to use than
other currently available EIA interface drivers. First, the
9616 has internal slew rate limiting which eliminates the

MIL-STD-188C low level interface" devices are often requested in conjunction with RS232-C capability. Fortunately, the
two standards have overlapping specifications (See Figure 57) so that one driver designed to satisfy the electrical requirements in MIL-STD-188C also satisfies the electrical requirements in RS232-C. The notable exception is the 5 to 15%
driver signal waveshaping requirement in 188C. The 9616
was designed with both specifications in mind, so only an
external capacitor on the 9616 output (as shown in Figure
5-9) is needed to perform the required waveshaping for MILSTD-188C at the desired modulation rate.

Where EIA RS232C and MIL-STD-188C (low level) are primarily intended for use on DTE-DCE interfaces, and are
formal standards, the IBM 360/370 1/0 interface is probably the best known example of an informal standard interface. The 1/0 interface 2 is the communications link between
a channel in the System 360 or System 370 computer and the
various 1/0 control units. The interface specification delineates electrical characteristics, information formats, and control sequences to pass information between the channel and
the peripheral control unit. The primary electrical characteristics are shown in Figure 5-10. The interface is a multipex' single-ended, unipolar variety designed to operate with
up to 10 ports on a double terminated 95
transmission line
of either coax or tri-lead 6 cable. The 8T23 and 8T24 devices
satisfy the requirements in the IBM document 2 for bus
drivers and bus receivers respectively. Their use is shown in
Figure 5-11.

The electrical characteristics for the receiver in both standards are somewhat different (see Figure 5-7) in input resistance and threshold levels, but both standards are satisfied by the 9627 dual EIAIMIL interface receiver. Option
strapping on the 9627 allows the user to choose the receiver
input resistance (either 3 to 7 kn or >6 kn) and threshold
levels. The 10% threshold matching requirement MIL-STD188C can be met with the 9627 by a trimming network as
shown in Figure 5-9.

than initially choosing the target system characteristics. The
former is a relatively simple process of comparing the device
characteristics to the design goals. The latter is a difficult
matter because of the large number of variables involved.
Designing from scratch, however, is not an impossible task.
The primary choices to be made are as follows:
•

Simplex or multiplex operation of the lines.

•

Single-ended or differential operation.

•

Pulse code.

•

Signal quality vs line length trade-off for particular pulse
codes selected.

•

Line termination method.

SYSTEMS CONSIDERATIONS
The following points should be considered when using transmission line interface circuitry.

•

•

•

Data rates above 10 Mbaud will usually require ECl to be
used instead of n l types for the drivers and receivers, because of the 20 to 50 ns propagation delays in the n l
compatible devices.

•

Liberal use of .01 to .1 jJF capacitors to decouple the power
supplies feeding line drivers and receivers is recommended. One capacitor per power supply for every two to four
devices is usually sufficient.

REFERENCES

With these choices in mind, Figure 5-12 was constructed to
recommend the optimum Fairchild devices for the particular
applications constraints.

The most limiting factor to data rate with long lines (> 50
feet) is usually the rise and fall time of the cable. The use
of the eye pattern allows easy measurement of signal quality (amount of time jitter).
Differential forms are preferable to single-ended forms
where high noise environments are present. Opto -isolators
and transformers offer high common mode operating
ranges and ground isolation. With transformers, a dc-free,
self-clocking code such as Bil/l (digital binary phase modulation) is useful.
The total number of ports on a multiplex system should be
restricted so that the parallel combination of the input
impedance of receivers and the output impedances of disabled drivers is greater than the characteristic resistance
of the transmission line.
Ground returns are necessary for proper operation of integrated circuit line drivers and receivers. This may be ac10-56

SATISFYING EIA STANDARDS RS-422 AND RS-423

The Electronic Industries Association, EIA, has this year released new standards for binary digital interfaces between Data Communication Equipment (modems), and Data Terminal Equipment (CRT Terminals, teletypewriters, etc.). These standards are RS-422, Electrical Characteristics of Balanced Voltage
Digital Interface Circuits, and RS-423, Electrical Characteristics of Unbalanced Voltage Digital Interface
Circuits. RS-423 replaces the electrical section of RS-232-C, the existing EIA standard, and expands its
capabilities to include operations at higher data rates and over greater distances. RS-422 incorporates a
technology not covered by RS-232-C, defining a balanced, differential, high speed interface. The following table provides a brief comparison of the recommended maximums for these standards.

Development of RS-422 and RS-423 was initiated during 1973 when the existing standard, RS-232-C
was due for review. (EIA reviews its standards on a five year cycle). At this time it was decided to bring
out a new standard that would eliminate the deficiencies of RS-232-C and to reconcile it with the standards CCITT V. 24 (now revised to V. 28) and MIL-STD-188C with the hope that one standard or very
similar standards would cover the military, international and commercial areas. In addition, it was intended that the resulting standard should be readily implemented with integrated circuitry and should
facilitate an orderly transition from existing RS-232-C equipment without forcing obsolescence or expensive retrofits. At this time the structure of standards at EIA was evolving such that three separate
standards, electrical, functional and mechanical, together would replace RS-232-C .

RS-422 Balanced Interface Circuit

10-58

There are several areas for improvement in the electrical section of RS-232-C. It has been felt that
the driver and receiver circuits as well as the interchange circuit, in general, were underspecified.
More specifically, the voltage levels of the interchange signals are larger than necessary or desirable at
± 15 V. The maximum cable length was too short at 50 feet, the data rate was too low at 20 kilobits-persecond, and no provision for multiple receivers was provided. Additionally, the low common mode
operating range and susceptibility to crosstalk made some applications risky. The interconnecting cable,
itself, was only addressed in terms of length and capacitance.
The influence of RS-422 and RS-423 has been pervasive. The proposed Federal Standards 1020 and
1030 accept RS-422 and RS-423, respectively, without change. The proposed MIL-STD-188-114 incorporates RS-422 and RS-423 with only a minor addition. These standards are also being utilized by
ANSI, the Public Data Networks Interface, and at the international level they are included in CCITT provisional recommendations X.26 (unbalanced) and X.27 (balanced).
RS-422 Driver (Balanced)
RS-422 allows either a unipolar or a polar driver. The unipolar approach offers a potentially cheaper
system as its operation requires only a single power supply but at the expense of introducing a common
mode component to the signal. The polar approach offers the potential of minimizing any common mode
signal, but requires two power supplies for operation.

The generator or driver specified in RS-422 is a circuit with low impedance, balanced, voltage source
outputs that provide a differential signal voltage in the range of 2 to 6 volts. (Refer to Figure 6-1). The two

In addition, the standard requires that the differential signal change monotonically in the transition region, defined as between the 10% and 90% pOints of the signal change, that any overshoot or undershoot be less than 10% of V ss , and at no time outside of the transition region shall the instantaneous
magnitude of Vt be greater than 6 volts or be less than 2 volts.

These fault conditions imply that the driver must withstand a 150 milliampere source with a voltage
range of ±10 volts (signal plus common mode) being connected to its outputs.

(I I

I)

The terminated output requirement Vt ~ 0.51 Vo limits the combined output impedance of the differential outputs to less than 100 ohms. Variations in the total output impedance between output states
are also limited. The output voltage matching specification Vt

less than 20 ohms in the case of the open circuit output voltage magnitudes being equal. An output offset
requirement ( Vos ~ 3.0 V) limits the amount of common mode signal the driver can generate. This requirement in conjunction with the offset matching specification further limits any mismatch between the
voltage levels or impedances of the two outputs. The output current range has a specified maximum
(lis ~150 mAl and an implied minimum of 20 milliamperes required by the combination of the minimum
signal (2.0 V) into a 100 ohm load.

I

I

I

The monotonicity requirement places a unique restriction on differential output circuits. It should be
noted that unless the transitions of the individual outputs overlap, a flat or zero-slope region develops in
the differential transition. While a zero-slope region, in itself, may not violate the monotonicity requirement, any ringing or system noise occurring at this point in time could. This requirement can be satisfied
if the individual transition times are kept longer than the device propagation delays; but, this eventually
compromises the system's maximum data rate. Closely matched propagation delays would permit high
speed operation while insuring a monotonic differential signal.

RS-423 Driver (Unbalanced)
The generator or driver specified in RS-423 is a circuit with a low impedance, unbalanced, voltage
source output that provides a signal of 4 to 6 V in magnitude. (Refer to Figure 6-7). The two Signal
states are defined as the MARK or OFF state when the A terminal of the driver is negative with respect to
terminal C and the SPACE or ON state when the A terminal is positive with respect to terminal C. A

As with the balanced driver, this implies that the unbalanced driver must withstand a 150 mA source with
a voltage range of ± 10 V being connected to its output

(I I

The unbalanced driver output impedance is established by the terminated output specification Vt
>0.9 Vo). Since there are no output matching or offset requirements, there are no restrictions on output
impedance or voltage levels matching between output states. If, however, the driver requires an external
waveshaping method which incorporates an external resistor, then a mismatch between states in the
output impedance could be of consequence. The output current range has a specified maximum (lis
~ 150 mA) and an implied minimum of 7.8 milliamperes required by the combination of a minimum signal
(4.0 V) into a 450 n load.

I

Since this is not a differential output device, the monotonicity requirements are not as complex as in the
case of the balanced driver. However, concern must be given to the amount of crossover distortion permitted during transitions.
RS-422/RS-423 Receiver
The standards RS-422 and RS-423 are written to have identical receiver specifications such that a
single device design could satisfy both standards. Such a receiver would operate in the balanced system
(RS-422) between the differential outputs of the driver and in the unbalanced system (RS-423) between
the driver output and the signal common return. The receiver specified in RS-422 and RS-423 is a differential circuit with balanced input impedance larger than 4 kilohms and a differential input threshold
magnitude less than 200 mV over a ±7 Vcommon mode range. A summary of the specifications is
contained in the following table.

Input Voltage Test Circuit
(RS-422/RS-423)

The graph used to specify the input current voltage characteristic of the receiver limits the input resistance to be greater than 4 kilohms when there exists a ± 3 V bias in the driver. Permitting an internal
bias allows receivers to be designed that require only a single power supply for operation. The input balance requirement restricts not only the input threshold accuracy of the receiver, but also any mismatch
of its input resistance.
New Products
Efforts are ongoing at Fairchild to develop a family of products satisfying these standards. The first of
these announced products are:
9634 Dual 3-State Differential Line Driver (RS-422 Driver)

DICE POLICY
GENERAL INFORMATION
Fairchild linear integrated circuits, constructed using the Fairchild Planar· epitaxial process, are
available in dice form incorporating these features:
•
•
•
•
•

Commercial or Military Selection (Military Limits Probed at 25°C)
M I L-STD-883, Method 2010.2, Condition B Visual
Gold Backing
Glass Passivation
Protective Packaging

ELECTRICAL CHARACTERISTICS
Each die electrically tested at 25°C to guarantee commercial dc parameters.
Military grade dice are guardband tested at 25°C dc to guarantee military temperature range
operation.
QUALITY ASSURANCE
All Fairchild linear dice are 100% visually inspected and conform to MI L-STD-883, Method 2010.2,
Condition B. In addition, quality control visually inspects the dice to a given sampling plan.
Each die is gold backed to aid die attach. Most diec are available with glass paSSivation coating with
only the bonding pads exposed.
SHIPPING PACKAGES
Linear dice are packaged in containers with an anti-static sheet inserted between the lid and the
dice. This sheet guards against electrostatic damage during shipment and storage.
The clear plastic carrier allows visual inspection of all the packaged dice. Each carrier is heat sealed
within a transparent bag. A small piece of dehydrator paper with humidity indicating color is
inserted in each bag prior to sealing.
ORDER INFORMATION
Each linear integrated circuit die has a unique order code which describes the device type, the dice
designation and type of electrical tests performed. The dice designation is denoted by a "C" and
wafer designation is denoted by a "W." Examples follow:
Generic Type

Dice
