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 transmission 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:

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.
