Overview
The MAX232BASE+T, produced by Analog Devices Inc./Maxim Integrated, is a dual driver/receiver integrated circuit designed to facilitate communication between devices using the RS-232 serial communication standard. This IC is particularly useful in systems that require conversion between RS-232 voltage levels and TTL/CMOS logic levels. It operates from a single 5V power supply and includes a capacitive voltage generator to produce the necessary voltage levels for RS-232 communication.
