The SN65LBC175 and SN75LBC175 are  
monolithic, quadruple, differential line receivers  
with 3-state outputs and are designed to meet the  
requirements of the EIA standards RS-422-A,  
RS-423-A, RS-485, andCCITTRecommendation  
V.11. The devices are optimized for balanced  
multipointbustransmissionatdataratesuptoand  
exceeding 10 million bits per second. The  
receivers are enabled in pairs, with an active-high  
enable input. Each differential receiver input  
features high impedance, hysteresis for  
increased noise immunity, and sensitivity of  
±200 mV over a common-mode input voltage  
range of 12 V to –7 V. The fail-safe design ensures  
that when the inputs are open-circuited, the  
outputs are always high. Both devices are  
designed using the TI proprietary LinBiCMOS  
technology allowing low power consumption, high  
switching speeds, and robustness.
