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.

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: 1. All voltage values, except differential input voltage, are with respect to the network ground terminal.
2. Differential input voltage is measured at the noninverting input with respect to the corresponding inverting input.
