MAX14782E:500Kbps 3.3V to 5V RS-485/RS-422 Transceiver with ±35kV HBM ESD Protection

Industry's Highest ESD Dual-Voltage RS-485/RS-422 Transceiver

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. The MAX14782E integrated protection 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. Hot-swap 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 low-power shutdown mode. The MAX14782E is available in 8-pin µMAX®, 8-pin SO, and small, 8-pin (3mm x 3mm) TDFN-EP packages. All packages operate over the -40°C to +125°C temperature range.
