Description
ICL3222EIBZ-T is a dual RS-232 transceiver (two drivers + two receivers) from Intersil/Renesas. It provides a complete RS-232 interface: TTL/CMOS logic on one side and RS-232 levels on the other, enabling microcontrollers to talk to PCs, modems, or other RS-232 devices. The device uses an onboard charge-pump to generate the required RS-232 voltages from a single supply (typical 3 V to 5.5 V) and requires external capacitors as per the datasheet. It’s packaged in a small IC package (with the -T indicating tape-and-reel shipping) and is suitable for low-power, two-channel serial interfaces. For exact pinout, voltage, data-rate limits, and capacitor values, consult the official datasheet.
