Overview
The MAX232ACUE+T is a dual driver/receiver integrated circuit designed for RS-232 communication interfaces. It is part of the MAX220–MAX249 family of line drivers/receivers produced by Analog Devices Inc./Maxim Integrated. 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+T includes a capacitive voltage generator that supplies the necessary voltage levels for TIA/EIA-232-F compliance from this single supply, making it highly versatile and efficient in various communication systems.
