Description

MAX3222EUP is an electronic component model categorized as Receivers & Transceivers. It is a transceiver with a proprietary low-dropout transmitter output stage that enables true RS-232 performance. It can operate from a 3.0V to 5.5V supply with a dual charge pump. The device only requires four small 0.1µF external charge pump capacitors. The MAX3222EUP, along with the MAX3232 and MAX3241 models, can run at data rates of 120kbps while maintaining RS-232 output levels. On the other hand, the MAX3237 model is guaranteed to run at data rates of 250kbps in normal operating mode and 1Mbps in the MegaBaud™ operating mode while maintaining RS-232 output levels.
