Overview

The ICL3232CBNZ is a dual-channel RS-232 transceiver designed for high-speed serial communication in systems powered by 3.0V to 5.5V supplies. It utilizes on-chip voltage converters that require only four external 0.1uF capacitors to provide full RS-232 voltage levels from a single low-voltage supply. This part is a drop-in replacement for the MAX3232 and is assured to support data rates up to 250kbps.

Why Choose This Part

This transceiver features 15kV ESD protection (HBM) and 300mV receiver hysteresis for improved noise immunity in harsh environments. It is highly efficient with a low 0.3mA typical supply current and a 10uA shutdown mode, making it suitable for battery-powered applications.

Applications

Industrial Control Interfaces
Providing robust serial communication between PLCs, HMIs, and industrial sensors over RS-232.
Embedded System Debugging
Converting TTL/CMOS logic levels from microcontrollers to RS-232 standard levels for PC-based terminal logging.
Legacy Peripheral Connectivity
Integrating modern 3.3V or 5V systems with legacy serial hardware such as barcode scanners and modems.

Getting Started

To implement this part, connect four 0.1uF ceramic capacitors to the internal charge pump pins (C1-C4) as specified in the datasheet. Ensure the Vcc supply is bypassed with a 0.1uF capacitor near the pin, and verify that the logic-side signals match the 3V to 5.5V supply voltage used.
