Analog Devices Inc. ADM3202Ax High-Speed Transceivers

Analog Devices ADM3202Ax High-Speed Transceivers operate on a +3.3V power supply making them ideal for battery-powered portable instruments. These 2-channel RS-232/V.28 transceivers operate at data rates up to 460kbps. Four external 0.1µF charge pump capacitors are used for the voltage doubler/inverter. The devices' EN input can be used to three-state the receiver outputs. The SD input is used to power down the charge pump and transmitter outputs, reducing the quiescent current to less than 0.5µA. The receivers remain enabled during the shutdown unless disabled using EN.
