Overview
The SN75175NSR is a monolithic quadruple differential line receiver produced by Texas Instruments. It is designed to meet the requirements of ANSI Standards 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. This component is optimized for balanced multipoint bus transmission at rates up to 10 megabits per second and is particularly suited for use in noisy environments.
The SN75175NSR features high input impedance, input hysteresis for increased noise immunity, and input sensitivity of ±200 mV over a common-mode input voltage range of ±12 V. It operates from a single 5-V supply and has low-power requirements, making it an efficient choice for various applications.
