Internal ESD protection circuits protect the transceiver bus terminals against ±16-kV Human Body Model (HBM) electrostatic discharges and ±4-kV electrical fast transients (EFT) according to IEC61000-4-4.

The SN65HVD1x half-duplex family provides internal biasing of the receiver input thresholds for open-circuit, bus-idle, or short-circuit fail-safe conditions, as well as a typical receiver hysteresis of 35 mV.
