2 Description

The SN75179B is a differential driver and

receiver pair designed for balanced transmission-line

applications and meets TIA/EIA-422-B, TIA/EIA-485-

A, and ITU Recommendation V.11. The device is

designed to improve the performance of full-duplex

data communications over long bus lines.

The SN75179B driver output provides limiting for both

positive and negative currents. The receiver features

high input impedance, input hysteresis for increased

noise immunity, and input sensitivity of ±200mV over

a common-mode input voltage range of –7V to 12V.

The driver provides thermal shutdown for protection

from line fault conditions. Thermal shutdown is

designed to occur at a junction temperature of

approximately 150°C. The SN75179B is designed to

drive current loads of up to 60mA maximum.

The SN75179B is characterized for operation from

0°C to 70°C.
