ST4485EB Series

The ST4485EB device is a ± 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 ST4485EB transmits and receives at a guaranteed data rate of at least 20 Mbps. All transmitter outputs and receiver inputs are protected to ± 15 kV using "Human Body Model". 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.
