MAX3232ECPE

Product Summary

The MAX3232ECPE is a true RS-232 Transceiver. The MAX3232ECPE +3.0V-powered EIA/TIA-232 and V.28/V.24 communications interface device features low power consumption, high data-rate capabilities, and enhanced electrostatic-discharge (ESD) protection. The enhanced ESD structure protects all transmitter outputs and receiver inputs to ±15kV using IEC 1000-4-2 Air-Gap Discharge, ±8kV using IEC 1000-4-2 Contact Discharge (±9kV for MAX3232ECPE), and ±15kV using the Human Body Model. The logic and receiver I/O pins of the MAX3232ECPE are protected to the above standards, while the transmitter output pins are protected to ±15kV using the Human Body Model. The applications of the MAX3232ECPE include battery-powered, equipment printers, cell phones smart phones, cell-phone data, cables xDSL modems, notebook, subnotebook, and palmtop computers.
