ST485EX, ST485EB Datasheet (STMicroelectronics)

ST485EX, ST485EB, RS-485/RS-422 transceiver

SO-8 Driver is short-circuit current limited and is protected against excessive power dissipation by thermal shutdown circuitry that place the driver outputs into a high-impedance state.

The ST485E is designed for bi-directional data communications on multipoint bus transmission lines (half-duplex
