Product Summary

The MAX3232 transceiver has a proprietary low-dropout transmitter output stage enabling true RS-232 performance from a 3.0V to 5.5V supply with a dual charge pump. It requires only four small 0.1μF external chargepump capacitors. The MAX3232 is guaranteed to run at data rates of 120kbps while maintaining RS-232 output levels. The applications of MAX3232 the include Notebook, Subnotebook, and Palmtop Computers, High-Speed Modems, Battery-Powered Equipment, Hand-Held Equipment, Peripherals, Printers.
