MAX3241ECAI+

The MAX3241ECAI+ is a True RS-232 Transceiver for cell-phone data cables. The MAX3241E +3.0V-powered EIA/TIA-232 and V.28/V.24 communications interface devices feature 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 and ±15kV using the human body model. A proprietary low-dropout transmitter output stage delivers true RS-232 performance from a +3.0 to +5.5V power supply, using an internal dual charge pump. The charge pump requires only four small 0.1μF capacitors for operation from a +3.3V supply. Each device guarantees operation at data rates of 250kbps while maintaining RS-232 output levels.
