ISL3332, ISL3333
3.3V, ±15kV ESD Protected, Two Port, Dual Protocol (RS-232/RS-485) Transceivers
FN6362 Rev 1.00 Jan 21, 2021
The ISL3332, ISL3333 are 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 onboard charge pump generates RS-232 compliant 5V Tx output levels from a single VCC supply as low as 3.15V. The transceivers are RS-232 compliant, with the Rx inputs handling up to 25V.
In RS-485 mode, the transceivers support both the RS-485 and RS-422 differential communication standards.
