Overview

The ICL3232IBNZ-T is a 3.0V to 5.5V powered RS-232 transceiver featuring two transmitters and two receivers. It utilizes an internal dual charge pump to maintain RS-232 output levels from a low-voltage supply while requiring only four small 0.1uF external capacitors. This part is a drop-in replacement for the industry-standard MAX3232 series with enhanced 15kV ESD protection.

Why Choose This Part

It offers guaranteed data rates up to 250kbps and a minimum slew rate of 6V/us for reliable high-speed communication. The device includes 15kV ESD protection (HBM) and 300mV of receiver hysteresis for superior noise immunity in harsh electrical environments.

Applications

Industrial Controller Debug Ports
Provides a robust serial interface for field service and configuration of PLCs and motor drives.
Legacy Peripheral Interfacing
Connects modern 3.3V or 5V microcontrollers to legacy RS-232 hardware such as barcode scanners and weighing scales.
Embedded System Console Access
Standard serial console port for headless Linux or RTOS based systems requiring RS-232 signal levels.

Getting Started

To implement this part, connect four 0.1uF capacitors to the charge pump pins (C1+/C1-, C2+/C2-, V+, and V-) and ensure Vcc is between 3V and 5.5V. Since it is a level shifter, simply route your MCU UART TX/RX lines to the TTL/CMOS side and the RS-232 connector to the RIN/TOUT pins.
