Overview
The SN75189ANSRG4, produced by Texas Instruments, is a monolithic low-power Schottky quadruple line receiver. This device is designed to meet the requirements of the standard interface between data-terminal equipment (DTE) and data-communication equipment (DCE) as defined by TIA/EIA-232-F and ITU Recommendation V.28. It operates from a single 5-V supply and is characterized for operation from 0°C to 70°C, making it suitable for a variety of communication applications.
