Overview
The UA9637A is a dual differential line receiver designed by Texas Instruments to meet the requirements of ANSI standards EIA/TIA-422-B and EIA/TIA-423-B, as well as ITU recommendations V.10 and V.11. This device uses high-speed Schottky circuitry and has TTL-compatible outputs. It operates from a single 5V power supply and is available in 8-pin dual-in-line (PDIP) and small-outline (SOIC) packages. The UA9637A is characterized for operation from 0°C to 70°C and is designed to be interchangeable with the National DS9637A.
