Product Summary

The MAX3232 is a transceiver. It 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 devices require 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. It has 2 receivers and 2 drivers. The MAX3232 features a 1μA shutdown mode that reduces power consumption and extends battery life in portable systems. Its receivers remain active in shutdown mode, allowing external devices such as modems to be monitored using only 1μA supply current. The MAX3232 is pin, package, and functionally compatible with the industry-standard MAX242 and MAX232, respectively.
