ST3485EBDR General 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.
