Renesas Electronics Multiprotocol Transceiver, ISL3331IRZ

The Renesas Dual Protocol (RS-232/RS-485) Transceiver is BiCMOS interface ICs that are user configured as either a single RS-422/RS-485 differential transceiver, or as a dual (2 Tx, 2 Rx) RS-232 transceiver. In RS-232 mode, the on-board charge pump generates RS-232 compliant ±5V Tx output levels, from a supply as low as 3.15V. Four small 0.1μF capacitors are required for the charge pump. The transceivers are RS-232 compliant with the Rx inputs handling up to ±25V.

Operates from a single 3.3V supply
5V tolerant logic inputs
Pb-free (RoHS compliant)
Full failsafe (open/short) Rx in RS-485/RS-422 mode
Loopback mode facilitates board self test functions
Fast RS-232 data rate up to 400kbps
