ISL3331 - Dual Protocol (RS-232/RS-485) Transceivers

Download the ISL3331 datasheet PDF. This datasheet also covers the ISL3330 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 failsafe" operation, so the Rx output remains in a high state if the inputs are open or shorted together. The RS-485 transmitter supports up to three data rates, two of which are slew rate limited for problem free communications. The charge pump disables in RS-485 mode, thereby saving power, mi.

DATASHEET ISL3330, ISL3331 3.3V, ±15kV ESD Protected, Dual Protocol (RS-232/RS-485) Transceivers FN6361 Rev 0.00 May 20, 2008 These devices are BiCMOS interface ICs that are user configured as either a single RS-422/RS-485 differential transceiver, or as a dual (2 Tx, 2 Rx) RS-232 transceiver. In RS-232 mode, the on-board charge pump generates RS-232 compliant ±5V Tx output levels, from a supply as low as 3.15V. Four small 0.1µF capacitors are required for the charge pump. 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.
