description
The SN75176A differential bus transceiver is a monolithic integrated circuit designed for bidirectional data
communication on multipoint bus-transmission lines. It is designed for balanced transmission lines and meets
ANSI Standard EIA/TIA-422-B and ITU Recommendation V.11.
The SN75176A combines 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 externally connected together 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 whenever 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.
The driver is designed to handle loads 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 k
, an input sensitivity of
±
200 mV, and a typical input hysteresis of 50 mV.
The SN75176A can be used in transmission-line applications employing the SN75172 and SN75174 quadruple
differential line drivers and SN75173 and SN75175 quadruple differential line receivers.
The SN75176A is characterized for operation from 0
°
C to 70
°
C.
