Overview
The MAX232AEUE+T is a +5V-powered, multichannel RS-232 driver/receiver integrated circuit produced by Analog Devices Inc./Maxim Integrated. This component is part of the MAX220–MAX249 family, designed for EIA/TIA-232E and V.28/V.24 communications interfaces. It is particularly useful in applications where a bipolar ±12V supply is not available.
The MAX232AEUE+T facilitates seamless communication between devices by integrating charge pump circuitry, which eliminates the need for an external bipolar supply. This makes it ideal for single supply operation from a +5V supply, saving board space and reducing power requirements.
