The ADM3232EARNZ is a high speed 2-channel Line Driver/Receiver operates from a single 3.3V power supply. Low power consumption makes it ideal for battery-powered portable instruments. The ADM3232E conforms to the EIA-232E and ITU-T V.28 specifications and operates at data rates up to 460kbps. All RS-232 inputs and outputs are protected against electrostatic discharges. This ensures compliance with IEC 1000-4-2 requirements. The interface device is ideally suited for operation in electrically harsh environments or where RS-232 cables are frequently plugged/unplugged with the ±15kV ESD protection of the ADM3232E RS-232 input/output pins. Emissions are also controlled to within very strict limits. CMOS technology is used to keep the power dissipation to an absolute minimum, allowing maximum battery life in portable applications. Four external 0.1μF charge pump capacitors are used for the voltage doubler/inverter, permitting operation from a single 3.3V supply.
