Overview
The MAX232BAWE+T, produced by Analog Devices Inc./Maxim Integrated, is a dual driver/receiver integrated circuit designed to meet the requirements of the TIA/EIA-232-F and ITU recommendation V.28 standards. This device is particularly useful for converting between the voltage levels of RS-232 and those of TTL/CMOS logic, enabling communication between devices that operate at different voltage levels. It features an integrated charge pump circuit that allows operation from a single 5V power supply, eliminating the need for a bipolar ±12V supply.
