Overview

The ICL3232EIBNZ is a 3.0V to 5.5V powered RS-232 transceiver featuring two drivers and two receivers. It is designed for low-power applications and maintains full RS-232 compliance even at 2.7V, making it ideal for battery-powered systems that require robust serial communication.

Why Choose This Part

This transceiver provides enhanced ESD protection up to +/-15kV (IEC61000) on RS-232 I/O pins, ensuring durability without external protection components. It requires only four small 0.1uF external capacitors for its on-chip voltage converters and supports data rates up to 250kbps.

Applications

Industrial Control Systems
Provides reliable serial communication between PLCs and human-machine interfaces in electrically noisy environments.
Battery-Powered Instruments
Utilizes a low 1uA shutdown current and efficient charge pumps to extend the battery life of portable diagnostic tools.
Embedded System Debugging
Acts as a level shifter between low-voltage microcontroller UARTs and legacy RS-232 serial ports.
Point-of-Sale Terminals
Facilitates data exchange between terminals and peripherals like barcode scanners or receipt printers.

Getting Started

To implement this device, connect four 0.1uF capacitors to the internal charge pump pins as specified in the datasheet for your supply voltage. Ensure the VCC pin is bypassed with a 0.1uF capacitor and keep the trace lengths short between the IC and the RS-232 connector to minimize EMI.
