Product Introduction

Overview

The MAX3232CDRE4, 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. It consists of two line drivers, two line receivers, and a dual charge-pump circuit, offering ±15-kV ESD protection terminal to terminal, including serial-port connection terminals and GND. The MAX3232 meets or exceeds the requirements of TIA/EIA-232-F and ITU V.28 standards, making it suitable for a wide range of applications.
