Overview
The MAX232NG4, produced by Texas Instruments, is a dual driver/receiver integrated circuit designed to meet or exceed the TIA/EIA-232-F and ITU recommendation V.28 standards. This device is particularly notable for its ability to operate from a single 5V power supply, eliminating the need for a bipolar ±12V supply. It includes an integrated charge pump circuitry that generates the necessary voltage levels for RS-232 communication from the single 5V supply.
