The MAX3222CPN+ is a low-power true RS-232 Transceiver for high-speed modems. The MAX3222 transceiver have a proprietary low-dropout transmitter output stage enabling true RS-232 performance from a 3.0 to 5.5V supply with a dual charge pump. The devices require only four small 0.1μF external charge pump capacitors. The MAX3222 is guaranteed to run at data rates of 120kbps while maintaining RS-232 output levels. The MAX3222 have 2 receivers and 2 drivers. The MAX3222 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.
