MAX14782EASA+

The MAX14782EASA+ is a 500Kbps, 3.3V to 5V, RS485/RS422 transceiver with ±35KV HBM ESD protection in 8 pin NSOIC package. It is a 3.3V to 5V ESD protected transceiver intended for half-duplex RS485/RS422 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 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. Typical application includes motion controllers, field bus networks, encoder interfaces and backplane buses.
