ISL33354E Dual Protocol (RS-232/RS-485) Transceivers

DATASHEET ISL33354E, ISL33357E 5V, ±15kV ESD Protected, Two Port, Dual Protocol (RS-232/RS-485) Transceivers FN8775 Rev 1.00 Oct 21, 2016 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.

ISL33354E 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
