Overview
The MAX232AC/D is a dual driver/receiver integrated circuit designed by Analog Devices Inc./Maxim Integrated. This component is specifically engineered to meet or exceed the TIA/EIA-232-F and ITU recommendation V.28 standards for serial communication. It is particularly useful in systems requiring RS-232 compatibility, including battery-powered devices, due to its low-power consumption and shutdown mode.
