ISL3333 Description
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 onboard charge pump generates RS-232 pliant 5V Tx output levels from a single VCC supply as low as 3.15V. The transceivers are RS-232 pliant, with the Rx inputs handling up to 25V.
