Product Introduction

Overview

The MAX3232IDRE4, produced by Texas Instruments, is a 3-V to 5.5-V multichannel RS-232 line driver and receiver. This device is designed to provide an electrical interface between an asynchronous communication controller and the serial-port connector, adhering to the TIA/EIA-232-F standards. It features a dual charge-pump circuit that allows operation from a single supply voltage, making it suitable for a variety of battery-powered and low-voltage systems.
