1 MICROCIRCUIT ILX3232N, ILX3232D INTERFACE TRANSCEIVER OF THE SERIAL DATA OF THE STANDARD RS -232 (compatible to MAX3232 (MAXIM USA) Microcircuits ILX3232 is interface transceiver of serial data under RS standard with single power supply source & bipolar output voltage of transmitter, forming by build-in voltage multiplier on 4 external capacities, 0. µf. ILX3232 correspond to EIA/TIA-232E, V.28 standard and is purposed for application in modern high efficient calculating systems with the wide range of supply voltage, fast-operating electronic devices with high level of fidelity of information exchange among distant devices. Functions and structure: Microcircuit contains 2 transmitters and 2 receivers of the serial data of the standard RS-232. The microcircuit supply voltage range is from 3.0 to 5.5 V. The microcircuits is available in -pin DIP-package (MS-00BB). -pin SO-package (MS-02AC).
