MAX232N Information

Description

The MAX232N is a line transceiver from Texas Instruments, designed for converting RS-232 voltage levels to TTL/CMOS levels. It's a dual-driver, dual-receiver device that operates from a single 5V power supply. The MAX232N meets or exceeds TIA/EIA-232-F and ITU Recommendation V.28 standards, making it suitable for various communication applications. This device is commonly used in embedded systems, industrial automation, networking equipment, and instrumentation to enable interfacing between different devices such as microcontrollers, computers, and serial devices. It features low supply current, ESD protection exceeding JESD 22, and operates up to 120 kbit/s. The MAX232N is an upgrade from earlier versions with improved ESD performance and reduced charge-pump capacitance.
