Overview
The MAX232ECWE+G104 is a dual EIA-232 driver/receiver integrated circuit produced by Analog Devices Inc./Maxim Integrated. This component is designed to convert signals between RS-232 voltage levels and TTL/CMOS voltage levels, making it ideal for interfacing microcontrollers or other TTL/CMOS devices with RS-232 compatible systems. The MAX232 operates from a single 5V power supply and includes an integrated charge pump circuit, eliminating the need for a bipolar ±12V supply.
