Internal ESD protection circuits protect the transceiver bus terminals against ±10-kV Human Body Model (HBM) electrostatic discharges and all other pins up to ±4 kV.

The SN65HVD1176 device provides internal biasing of the receiver input thresholds for open-circuit, bus-idle, or short-circuit failsafe conditions, and a typical receiver hysteresis of 40 mV.
