Overview
The SN75175NS is a monolithic quadruple differential line receiver produced by Texas Instruments. It is designed to meet or exceed the requirements of ANSI standards EIA/TIA-422-B, RS-423-B, and RS-485, as well as ITU recommendations V.10, V.11, X.26, and X.27. This component is optimized for multipoint bus transmission on long bus lines in noisy environments and features 3-state outputs.
The SN75175NS operates from a single 5-V supply, has low power requirements, and is a plug-in replacement for the MC3486. It is characterized for operation from 0°C to 70°C, making it suitable for a variety of industrial and commercial applications.
