10 sold in last 24 hours
The MAX232 is a popular integrated circuit used for converting signals between RS-232 voltage levels and TTL (transistor-transistor logic) voltage levels. It includes two drivers and two receivers, making it suitable for interfacing microcontrollers and other TTL-level devices with RS-232 serial ports commonly found in computers and peripherals. The MAX232 eliminates the need for external components typically required for RS-232 communication, simplifying circuit design and reducing component count.
