Overview
The SN65LBC175A, produced by Texas Instruments, is a quadruple differential line receiver designed to meet the requirements of EIA standards RS-422-A, RS-423-A, RS-485, and CCITT Recommendation V.11. This device is optimized for balanced multipoint bus transmission and is particularly suited for noisy environments and long bus lines. It features 3-state outputs and is enabled in pairs with an active-high enable input. The SN65LBC175A is part of the LinBiCMOS™ technology family, which ensures low power consumption, high switching speeds, and robust performance.
