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. It is designed to improve the

performance of full-duplex data communications over long bus lines.

TheSN75179Bdriveroutputprovideslimitingforbothpositiveandnegativecurrents. Thereceiverfeatureshigh

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.
