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 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

Ω, 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.
