description

The SN75157 is a dual differential line receiver designed to meet Standards EIA/TIA-422-B and -423-B and ITU

V.10 and V.11. It utilizes Schottky circuitry and has TTL-compatible outputs. The inputs are compatible with

either a single-ended or a differential-line system. The device operates from a single 5-V power supply and is

supplied in 8-pin dual-in-line and small-outline packages.

The SN75157 is characterized for operation from 0°C to 70°C.
