Overview

The ICL3232CPZ is a low-power, dual-channel RS-232 transceiver designed for 3V to 5.5V systems. It utilizes an internal charge pump with four external 0.1uF capacitors to generate the required RS-232 voltage levels from a single low-voltage supply. This through-hole PDIP version is particularly useful for legacy hardware interfaces and prototyping.

Why Choose This Part

The device features 15kV ESD protection (HBM) and is latch-up free, ensuring reliability in harsh electrical environments. It consumes very little power with a 0.3mA run current and supports data rates up to 250kbps, exceeding basic RS-232 requirements.

Applications

Industrial PLC Debugging
Provides a robust serial interface for programmable logic controllers that require standard RS-232 signal levels.
Embedded System Console Access
Enables serial console communication between a low-voltage microcontroller and a standard PC serial port.
Legacy Peripherals
Interfacing modern 3.3V or 5V logic with older RS-232 based equipment like barcode scanners or scales.

Getting Started

To implement this part, connect four 0.1uF charge pump capacitors as specified in the datasheet to the V+, V-, and C pins. For breadboard prototyping, ensure the 16-PDIP package is seated firmly and use a regulated 3.3V or 5V rail for VCC. No software configuration is required as the transceiver operates purely at the physical layer.
