±15kV ESD-Protected, Down to 10nA, 3.0V to 5.5V, Up to 1Mbps, True RS-232 Transceivers
________________General Description
The MAX3222E, MAX3232E, MAX3237E, MAX3241E are 3V-powered EIA, TIA-232 and V.28, V.24 communications interfaces 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 AirGap Discharge, ±8kV using IEC 1000-4-2 Contact Discharge, and ±15kV using the Human Body Model. The MAX3237E’s 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 transceivers have 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 requires only four small 0.1 F capacitors for operation from a +3.3V supply. Each device is guaran.
