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

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:

A Version

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.

Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

NOTES: 3. All voltage values, except differential voltages, are with respect to network ground terminal.

4. Differential voltage values are at the noninverting (A) terminal with respect to the inverting (B) terminal.

5. Common-mode input voltage is the average of the voltages at the A and B inputs.
