Description

The ST3485E is ±15 kV ESD protected, 3.3 V low

power transceiver for RS-485 and RS-422

communications. The device contains one driver

and one receiver in half duplex configuration. The

ST3485E transmits and receives at a guaranteed

data rate of at least 12 Mbps.

All transmitter outputs and receiver inputs are

protected to ±15 kV using Human Body Model.

Driver is short-circuit current limited and is

protected against excessive power dissipation by

thermal shutdown circuitry that places the driver

outputs into a high-impedance state.
