ADM4168E ±15 kV ESD Protected Dual RS-422 Transceiver

The ADM4168E has dual RS-422 transceivers suitable for high speed communication on point-to-point and multidrop transmission lines. The ADM4168E is designed for balanced transmission lines and complies with TIA/EIA-422-B. Applications

The differential driver outputs and receiver inputs feature electrostatic discharge circuitry that provides protection up to ±15 kV 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.

The receivers of the ADM4168E contain a fail-safe feature that results in a logic high output state if the inputs are unconnected (floating).

The ADM4168E is fully specified over the commercial and industrial temperature ranges and is available in a 16-pin TSSOP package.
