SN75179BP

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. It 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 ?200 mV over a
common-mode input voltage range of ?7 V to 12 V. 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 60 mA maximum.
The SN75179B is characterized for operation from 0?C to 70?C.
