Overview
The UA9637ACPS is a dual differential line receiver produced by Texas Instruments. This device is designed to meet or exceed the requirements of ANSI standards EIA/TIA-422-B and EIA/TIA-423-B, as well as ITU recommendations V.10 and V.11. It operates from a single 5V power supply and is available in 8-pin small-outline packages (SOIC and SOP). The UA9637ACPS utilizes high-speed Schottky circuitry, providing TTL-compatible outputs and high input impedance. It is characterized for operation from 0°C to 70°C and is designed to be interchangeable with the National DS9637A.
