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.

All voltage values, except differential input voltage, are with respect to network ground terminal. 2. Differential input voltage is measured at the noninverting input with respect to the corresponding inverting input. 3.
