SN65176BP Datasheet PDF - TI

●The SN65176BP is a Differential Bus Transceiver 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 SN65176B device combines a 3-state differential line driver and a differential input line receiver, both of which operate from a single 5V 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. This port features wide positive and negative common-mode voltage ranges, making the device suitable for party-line applications.
