ISL33337E - Dual Protocol (RS-232/RS-485) Transceivers

Download the ISL33337E datasheet PDF. This datasheet also covers the ISL33334E variant, as both devices belong to the same dual protocol (rs-232/rs-485) transceivers family and are provided as variant models within a single manufacturer datasheet.

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 control, via a single signal, simply by connecting the correspon.

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 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.
