The SN55LBC173-DIE is a monolithic quadruple differential line receiver with 3-state outputs designed to meet the requirements of the EIA standards RS-422-A, RS-423-A, RS-485, and CCITT V.11. This device is optimized for balanced multipoint bus transmission at data rates. The four receivers share two ORed enable inputs, one active when high, the other active when low. Each receiver features high input impedance, input hysteresis for increased noise immunity. Fail-safe design ensures that if the inputs are open circuited, the output is always high. The SN55LBC173-DIE is designed using the Texas Instruments proprietary LinBiCMOSE technology that provides low power consumption, high switching speeds, and robustness.
