ISL33334E, Dual Protocol (RS-232/RS-485) Transceivers

DATASHEET ISL33334E, ISL33337E 3.3V, ±15kV ESD Protected, Two Port, Dual Protocol (RS-232/RS-485) Transceivers FN8776 Rev 1.00 October 21, 2016 The ISL33334E, ISL33337E 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/RS-422 transceiver.

The on-board 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

ISL33334E 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 (RE485) allows Tx/Rx direction co
