description

These circuits are TTL-compatible, high-speed

line receivers. Each is a monolithic dual circuit

featuring two independent channels. They are

designed for general use, as well as for such

specific applications as data comparators and

balanced, unbalanced, and party-line transmis-

sion systems. These devices are unilaterally

interchangeable with and are replacements for

the SN55107, SN75107, and SN75108, but offer

diode-clamped strobe inputs to simplify circuit

design.

The essential difference between the A and B versions can be seen in the schematics. Input-protection diodes

are in series with the collectors of the differential-input transistors of the B versions. These diodes are useful

in certain party-line systems that have multiple V

CC+

power supplies and can be operated with some of the V

CC+

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:

Input

A Version

Input

B Version

This would be a problem in specific systems that might have the transmission lines biased to some potential

greater than 1.4 V.

The SN55107A is characterized for operation over the full military temperature range of –55°C to 125°C. The

SN75107A, SN75107B, and SN75108A are characterized for operation from 0°C to 70°C.

The system operates in the balanced mode, so noise induced on one line is also induced on the other.
