description/ordering information (continued)
The driver is designed for up to 60 mA of sink or source current. The driver features positive and negative current
limiting and thermal shutdown for protection from line-fault conditions. Thermal shutdown is designed to occur
at a junction temperature of approximately 150
°
C. The receiver features a minimum input impedance of 12 k
,
an input sensitivity of
±
200 mV, and a typical input hysteresis of 50 mV.
The SN65176B and SN75176B can be used in transmission-line applications employing the SN75172 and
SN75174 quadruple differential line drivers and SN75173 and SN75175 quadruple differential line receivers.
