Product Summary

The MAX3232CPE 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. The device require only four small 0.1μF external chargepump capacitors. The MAX3232CPE is guaranteed to run at data rates of 120kbps while maintaining RS-232 output levels. The MAX3232CPE has 2 receivers and 2 drivers. The MAX3232CPE is pin, package, and functionally compatible with the industry-standard MAX242 and MAX232, respectively. The applications of it are Notebook, Subnotebook, and Palmtop Computers, High-Speed Modems, Battery-Powered Equipment, Hand-Held Equipment, Peripherals, Printers.
