Description

The MAX3222/MAX3232/MAX3237/MAX3241 trans ceivers have a proprietary low-dropouttransmitter out put 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 charge pump capacitors. The MAX3222, MAX3232, and MAX3241 are guaranteed to run at datarates of 120kbps while maintaining RS-232 output levels. The MAX3237 is guaranteed to run at data rates of 250kbps in the normal operating mode and1Mbps in the MegaBaud™ operating mode, while maintaining RS-232 output levels.
