ST1480AB 3.3V POWERED, 15KV ESD PROTECTED TRASMIT AT UP TO 12MBPS TRUE RS-485/RS422 TRANSCEIVER

The ST1480A is ±15kV ESD protected, 3.3V low power transceiver for RS-485 and RS-422 communications. The device contains one driver and one receiver in half duplex configuration.

The ST1480A transmits and receives at a guaranteed data rate of at least 12Mbps.

All transmitter outputs and receiver inputs are protected to ±15kV 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.

The ST1480A input has a true fail-safe feature that guarantees a logic high output if both inputs are open circuit, shorted together or in the presence of a termination with no signal on the bus
