Overview

The ICL3232IVZ-T is a 3.0V to 5.5V powered RS-232 transceiver that provides 2-channel transmit and 2-channel receive capabilities. It is designed for low-power applications, consuming only 0.3mA of supply current while ensuring data rates up to 250kbps.

Why Choose This Part

The device features 15kV ESD protection (HBM) and is a functional drop-in replacement for standard MAX3232 parts. It operates across a wide supply range of 3.0V to 5.5V using only four external 0.1uF charge pump capacitors, simplifying BOM management.

Applications

Embedded System Console Access
Provides a robust RS-232 interface for serial debugging and console access to microcontrollers in industrial environments.
Legacy Peripheral Interfacing
Enables modern 3.3V or 5V logic systems to communicate with legacy hardware such as barcode scanners or PLC serial ports.
Handheld Diagnostic Tools
Utilizes the low 1uA shutdown current and small 16-TSSOP footprint for portable, battery-operated serial equipment.
