The SN751177 and SN751178 driver outputs provide limiting for both positive and negative currents and thermal-shutdown protection from line-fault conditions on the transmission bus line.
The receiver features high input impedance of at least 12 kΩ, an input sensitivity of ±200 mV over a common-mode input voltage range of –12 V to 12 V, and typical input hysteresis of 50 mV.
Fail-safe design ensures that if the receiver inputs are open, the receiver outputs always will be high.
The SN751177 and SN751178 are characterized for operation from –20°C to 85°C.
