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
is disabled or V
CC
= 0. This port features wide positive and negative common-mode voltage ranges, making
the device suitable for party-line applications. Very low device supply current can be achieved by disabling the
driver and the receiver.
