The ISL33354E, ISL33357E are two port interface ICs where port 1 is configured as a dual (2 Tx, 2 Rx) RS-232 transceiver, and port 2 is a single RS-485/422 transceiver.
An on-board charge pump generates RS-232 compliant ±5V Tx output levels from a single VCC supply as low as 4.5V. The transceivers are RS-232 compliant, with the Rx inputs handling up to ±25V.
The port 2 transceiver supports both the RS-485 and RS-422 differential communication standards. The receiver features "full fail-safe" operation, so the Rx output remains in a high state if the inputs are open or shorted together. The transmitter supports two data rates, one of which is slew rate limited for problem free communication at low data rates. The active low Rx enable pin (span style="text-decorati
The ISL33354E and ISL33357E also include a shutdown function, which disables the Tx and Rx outputs, disables the charge pumps and places the IC in a low current (55µA) mode.
The ISL33357E is a QFN packaged device for space constrained applications.
