Overview

The ICL3243EIAZ-T is a low-power, 3-driver and 5-receiver RS-232 transceiver designed for 3V to 5.5V systems. It features an integrated charge pump to generate RS-232 voltage levels from a single supply and includes an automatic power-down function that reduces supply current to 1uA when the serial port is inactive.

Why Choose This Part

The device offers a wide supply voltage range of 3.0V to 5.5V and supports data rates up to 250kbps, exceeding standard RS-232 requirements. Its 500mV receiver hysteresis ensures reliable communication in noisy environments, while the 28-SSOP package provides a compact footprint for multi-channel transceivers.

Applications

Battery-Powered Portables
Ideal for handheld instruments and PDAs where the 1uA shutdown current significantly extends battery life.
Legacy Industrial Interfacing
Connecting modern 3.3V or 5V microcontrollers to legacy RS-232 industrial equipment and PLC programming ports.
Embedded System Console Ports
Provides a robust serial debugging interface for networking hardware and server motherboards.
Peripheral Connectivity
Used in modems, printers, and barcode scanners requiring standard RS-232 signal levels and flow control.

Getting Started

To implement this part, place four 0.1uF charge pump capacitors as close to the IC as possible to ensure stable voltage doubling and inversion. Connect the FORCEON and FORCEOFF pins to your microcontroller to manage the automatic power-down states, and ensure the 28-SSOP land pattern follows IPC-7351 standards for reliable surface mount soldering.
