MAX3232E

Product Summary

The MAX3232E is a 3V-powered EIA/TIA-232 and V.28/V.24 communication interface with low power requirements, high datarate capabilities, and enhanced electrostatic discharge (ESD) protection. All transmitter outputs and receiver inputs are protected to ±15kV using IEC 1000-4-2 Air-Gap Discharge, ±8kV using IEC 1000-4-2 Contact Discharge, and ±15kV using the Human Body Model. The MAX3232E logic and receiver I/O pins are protected to the above standards, while the transmitter output pins are protected to ±15kV using the Human Body Model. The transceiver MAX3232E has a proprietary low-dropout transmitter output stage, delivering true RS-232 performance from a +3.0V to +5.5V supply with a dual charge pump. The charge pump of the MAX3232E requires only four small 0.1μF capacitor for operation from a +3.3V supply. Each device is guaranteed to run at data rates of 250kbps while maintaining RS-232 output levels. The MAX3232E is guaranteed to run at data rates of 250kbps in the normal operating mode and 1Mbps in the MegaBaud. operating mode while maintaining RS-232-compliant output levels.
