Product Introduction

Overview

The MAX3232EID, 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 the electrical interface between an asynchronous communication controller and the serial-port connector, adhering to the TIA/EIA-232-F and ITU V.28 standards. It features a dual charge-pump circuit that allows operation from a single 3-V to 5.5-V supply, making it versatile for various applications. The MAX3232EID includes two line drivers and two line receivers, and it is notable for its high ESD protection and low supply current.
