Описание
ADM3222 is a low power, 3.3V, RS-232 line driver/receiver. This transceiver is high speed, 2-channel RS-232/V.28 interface devices that operate from a single 3.3V power supply. Low power consumption and a shutdown facility make it ideal for battery-powered portable instrument. It is conforms to the EIA-232E and CCITT V.28 specifications and operate at data rates up to 460Kbps. Four external 0.1µF charge pump capacitors are used for the voltage doubler/inverter, permitting operation from a single 3.3V supply. 2 contains additional enable and shutdown circuitry. The active-low EN input can be used to three-state the receiver outputs. The active-low 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 shutdown unless disabled using active-low EN. Applications include general-purpose RS-232 data link, portable instruments, printers, palmtop computers and PDAs.
