SNx5176B Differential Bus Transceivers
1 Features
3 Description


The SN65176B and SN75176B differential bus
transceivers are 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 devices combine a 3state 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 activehigh 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. These
ports feature wide positive and negative commonmode voltage ranges, making the device suitable for
party-line applications.
The driver is designed for up to 60 mA of sink or
source current. The driver features positive and
negative current limiting and thermal shutdown for
protection from line-fault conditions. Thermal
shutdown is designed to occur at a junction
temperature of approximately 150°C. The receiver
features a minimum input impedance of 12 kΩ, an
input sensitivity of ±200 mV, and a typical input
hysteresis of 50 mV.
