The SN75178BP is a monolithic differential Bus Repeater designed for one-way data communication on multipoint bus transmission lines. It is designed for balanced transmission bus line applications and meets EIA standard RS-422-A and RS-485 and CCITT recommendations V.11 and X.27. Each device is designed to improve the performance of the data communication over long bus lines. It is identical except for the complementary enable inputs, which allow the devices to be used in pairs for bidirectional communication. It features positive- and negative-current limiting 3-state outputs for the receiver and driver. The receiver features high input impedance, input hysteresis for increased noise immunity and input sensitivity of ±200mV over a common-mode input voltage range of -7 to 12V.
