Description

The ST3485EB/EC/EI/EIY device 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 device transmits and receives at a

guaranteed data rate of at least 12 Mbps.

All transmitter outputs and receiver inputs are

protected to ±15 kV IEC 61000-4-2 air discharge.

The 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.
