Overview
The SN75175NSRE4, produced by Texas Instruments, is a monolithic quadruple differential line receiver with 3-state outputs. This component is designed to meet the requirements of various ANSI standards, including EIA/TIA-422-B, RS-423-B, and RS-485, as well as several ITU recommendations such as V.10, V.11, X.26, and X.27. It is optimized for balanced multipoint bus transmission at rates up to 10 megabits per second, making it suitable for use in noisy environments and long bus lines.
