MAX232 Description

Short technical summary and product information.

The MAX232 from N-A is a dual driver and receiver IC that meets or exceeds TIA/EIA-232-F and ITU recommendation V.28 standards. It operates from a single 5V power supply, utilizing charge-pump capacitors to generate the necessary TIA/EIA-232-F voltage levels. Each of the two receivers converts TIA/EIA-232-F inputs to 5V TTL/CMOS levels, featuring a typical threshold of 1.3V and 0.5V hysteresis, with the ability to accept ±30V inputs.

 

Each of the two drivers converts TTL/CMOS input levels into TIA/EIA-232-F levels. The device supports data rates up to 120kbit/s and has a low supply current of 8mA typical. For ESD protection, it exceeds JESD 22 standards with 2000V Human-body model (A114-A) protection. The MAX232 is available in various package types including SOIC, PDIP, and SOP.

 

This component is suitable for applications such as battery-powered systems, terminals, modems, and computers requiring RS-232 communication interfaces. Its robust input level tolerance and ESD protection make it a reliable choice for interfacing between microcontrollers and serial communication ports.
