Product Introduction

Overview

The MAX3232IDRG4, 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 two line drivers, two line receivers, and a dual charge-pump circuit, enabling operation from a single supply voltage. The MAX3232IDRG4 is packaged in a 16-pin SOIC (Small Outline Integrated Circuit) and is known for its robust ESD protection and efficient power management.
