MAX14782E

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

with ±35kV HBM ESD Protection

General Description

Beneﬁts and Features

●ꢀ IntegratedꢀProtectionꢀIncreasesꢀRobustnessꢀ

The MAX14782E is a 3.3V to 5V ESD-protected trans-

ceiver intended for half-duplex RS-485/RS-422 com-

munication up to 500kbps. The device is optimized for

extended cable runs while maximizing tolerance to noise.

• High ESD Protection

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.

●ꢀ DataꢀRatesꢀupꢀtoꢀ500kbps

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.
