MAX3086EESD+

MAX3086EESD+ is a fail-safe, high-speed, transceiver for RS485/RS-422 communication that contains one driver and one receiver. This device features fail-safe circuitry, which guarantees a logic-high receiver output when the receiver inputs are open or shorted. This means that the receiver output will be a logic high if all transmitters on a terminated bus are disabled (high impedance). This transceiver typically draws 375µA of supply current when unloaded, or when fully loaded with the drivers disabled. Applications include RS-422/RS-485 communications, level translators, transceivers for EMI-sensitive applications, industrial-control local area networks.
