The MAX14780E +5.0V, 30kV ESD-protected, RS-485/ RS-422 transceiver features one driver and one receiver. The device includes fail-safe circuitry, guaranteeing a logic-high receiver output when receiver inputs are open or shorted. The receiver outputs a logic-high if all transmitters on a terminated bus are disabled (high impedance). The MAX14780E includes a hot-swap capability to eliminate false transitions on the bus during power-up or hot insertion.
