Overview
The SN75175DR, produced by Texas Instruments, is a monolithic quadruple differential line receiver designed to meet the requirements of various industry standards including 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 and is particularly suited for use in noisy environments and long bus lines.
The SN75175DR features 3-state outputs and is compatible with the SN75172 or SN75174 quadruple differential line drivers for optimal performance. It operates from a single 5-V supply and has low-power requirements, making it an efficient choice for various industrial and automation applications.
