The SN75176A differential bus transceiver is a
monolithic integrated circuit designed for
bidirectional data communication on multipoint
bus-transmission lines. It is designed for balanced
transmission lines and meets ANSI Standard
EIA/TIA-422-B and ITU Recommendation V.11.
The SN75176A combines a 3-state differential line driver and a differential input line receiver, both of which
operate from a single 5-V power supply. The driver and receiver have active-high and active-low enables,
respectively, that can be externally connected together to function as a direction control. The driver differential
outputs and the receiver differential inputs are connected internally to form differential input /output (I/O) bus
ports that are designed to offer minimum loading to the bus whenever the driver is disabled or VCC = 0. These
ports feature wide positive and negative common-mode voltage ranges making the device suitable for party-line
