Overview
The MAX232ACUE is a dual driver/receiver integrated circuit designed for RS-232 communication interfaces. It is manufactured by Analog Devices Inc./Maxim Integrated and is part of the MAX232 series. This device is particularly useful in applications where a bipolar ±12V supply is not available, as it operates from a single 5V power supply. The MAX232ACUE includes a capacitive voltage generator that supplies the necessary voltage levels for TIA/EIA-232-F compliance using four external capacitors.
