APPLICATIONS RS-422 interfaces High data rate motor control Single-ended to differential signal conversion Point to point and multidrop transmission systems GENERAL DESCRIPTION The ADM4168E is a dual RS-422 transceiver suitable for high The receivers of the ADM4168E contain a fail-safe feature that speed communication on point to point and multidrop results in a logic high output state if the inputs are unconnected transmission lines. The ADM4168E is designed for balanced (floating). transmission lines and complies with TIA/EIA-422-B. The ADM4168E is fully specified over the commercial and The differential driver outputs and receiver inputs feature electro- industrial temperature ranges and is available in a 16-lead static discharge (ESD) circuitry that provides protection up to TSSOP package. 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. Short- circuit protection circuits limit the maximum output current to 150 mA during fault conditions. Rev.
