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

These ports feature wide positive and negative common-mode voltage ranges, making the device suitable for

party-line applications.
