Renesas Electronics Multiprotocol Transceiver, ISL3333IRZ-T7A

The Renesas Dual Protocol (RS-232/RS-485) Transceiver is two port interface ICs where each port can be independently configured as a single RS-485/422 transceiver or as a dual (2 Tx, 2 Rx) RS-232 transceiver. With both ports set to the same mode two RS-485/RS-422 transceivers or four RS-232 transceivers are available. If either port is in RS-232 mode the on-board charge pump generates RS-232 compliant 5V Tx output levels from a single VCC supply as low as 3.15V.
