Description

The ST1480A 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 ST1480A 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.

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.
