Overview
The SN65175DR, produced by Texas Instruments, is a monolithic quadruple differential line receiver with 3-state outputs. 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 SN65175DR operates from a single 5-V supply, has low-power requirements, and features high input impedance and input hysteresis for increased noise immunity. It is characterized for operation from −40°C to 85°C, making it versatile for various industrial and commercial applications.
