Présentation

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.

Note: These are all dual RS-232 transceivers with external capacitors; verify pinout and supply voltage (3.3V/5V) for your board.

Features

Here are the typical features of ICL3222EIBZ-T (RS-232 transceiver):
- Dual-channel: 2 drivers and 2 receivers (quad RS-232 transceiver)
- Single-supply operation: 3V–5.5V supply
- External-charge-pump method to generate RS-232 levels (requires external capacitors)
- TTL/CMOS-compatible inputs and RS-232 level outputs
- Data rates up to about 1 Mbps (typical)
- ESD and short-circuit protection on RS-232 lines
- Low power consumption
- Packaging: 16-pin TSSOP (EIBZ-T), RoHS-compliant (Tape & Reel option)

Pinout

- Pin count: 16-pin package (DIP-16/SO-16)
- Function: Dual RS-232 transceiver (two drivers and two receivers) that converts TTL/CMOS logic levels to RS-232 levels and RS-232 levels back to TTL/CMOS; uses a charge-pump with external capacitors to generate the RS-232 voltages.

Manufacturer

- Manufacturer: ICL (Integrated Circuit Labs).
- Company type: A semiconductor company that designs and manufactures integrated circuits (ICs) for electronics applications.

Application

ICL3222EIBZ-T is a dual RS-232 transceiver. Typical application areas include:
