Overview
The UA9637ACPSRG4 is a dual differential line receiver produced by Texas Instruments. This component 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. Although the UA9637A series is now obsolete, it was widely used in various industrial and communication applications. The device operates from a single 5V power supply and is available in 8-pin dual-in-line (PDIP) and small-outline (SOIC) packages.
