Overview
The MAX232ESE+T is a dual RS-232 driver/receiver integrated circuit produced by Analog Devices Inc./Maxim Integrated. This component is designed to meet or exceed the TIA/EIA-232-F and ITU recommendation V.28 standards. It operates from a single 5V power supply and is particularly useful in applications where ±12V is not available, such as battery-powered systems. The MAX232ESE+T is known for its low-power consumption and compact design, making it ideal for space-critical applications.
