description (continued)

The SN65LBC176A, SN65LBC176AQ, and SN75LBC176A combine 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, which can externally connect together to function as a

direction control. The driver differential outputs and the receiver differential inputs connect internally to form a

differential input /output (I/O) bus port that is designed to offer minimum loading to the bus whenever the driver

the device suitable for party-line applications. Very low device supply current can be achieved by disabling the

driver and the receiver.
