Overview
The MAX232AESE+T is a dual transmitter/receiver RS-232 interface IC 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 suited for applications where ±12V supplies are not available, allowing single supply operation from a +5V supply. The MAX232AESE+T features integrated charge pump circuitry, which eliminates the need for external bipolar ±12V supplies, making it highly efficient and space-saving.
