SN75176 - Differential Bus Transceiver

The SN75176B differential bus transceiver is an integrated circuit designed for bidirectional data communication on multipoint bus transmission lines. it is designed for balanced transmission lines and meets ANSI Standards TIA/EIA-422-B and TIA/EIA-485-A and ITU Recommendations V.11 and X.27. 

The SN75176B combines a 3-state differential line driver and a differential input line receiver, it operates from a single 5-V power supply. The driver and receiver have active-high and active-low enables, respectively, that can be connected together externally 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 when 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 applications.
