The ADM4168E is designed for balanced transmission lines and complies with TIA/EIA-422-B. The differential driver outputs and receiver inputs feature electrostatic discharge (ESD) circuitry that provides protection up to ±15 kV human body model (HBM) and ±8 kV IEC 61000-4-2 (contact and air discharge). The ADM4168E operates from a single 5 V power supply. Excessive power dissipation caused by bus contention or output shorting is prevented by short-circuit protection circuitry. Shortcircuit protection circuits limit the maximum output current to −150 mA during fault conditions. ±15 kV ESD Protected, Dual RS-422 Transceiver ADM4168...
