description/ordering information
The SN65176B and SN75176B differential bus transceivers are integrated circuits designed for bidirectional
data communication on multipoint bus transmission lines. They are designed for balanced transmission lines
and meet ANSI Standards TIA/EIA-422-B and TIA/EIA-485-A and ITU Recommendations V.11 and X.27.
The SN65176B and SN75176B 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, 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 V_CC = 0.
These ports feature wide positive and negative common-mode voltage ranges, making the device suitable for
party-line applications.
