MAX14782E - 500Kbps 3.3V to 5V RS-485/RS-422 Transceiver

General Description

The MAX14782E is a 3.3V to 5V ESD-protected transceiver intended for half-duplex RS-485/RS-422 communication up to 500kbps.

The device is optimized for extended cable runs while maximizing tolerance to noise.

Key Features

  • include short-circuit-protected outputs, hot-swap functionality, and a true fail-safe receiver, guaranteeing a logic-high receiver output when inputs are shorted or open. Hotswap capability eliminates undesired transitions on the bus during power-up or hot insertion. The transceiver draws 1.9mA (typ) supply current when unloaded or when fully loaded with the drivers disabled and draws less than 10µA (max) of supply current in lowpower shutdown mode. The MAX14782E is available in 8-pin µMAX®, 8-p.
