ADM222ARZ

ADM222 is a high-speed RS-232 line driver/receiver. It has highly efficient on-chip charge pump using small (0.1µF) external capacitors allows RS-232 bipolar levels to be developed. This line driver is fabricated on BiCMOS, an advanced mixed technology process that combines low power CMOS with high-speed bipolar circuitry. This allows for transmission rates upto 200kB/s. It contains an additional shutdown (active-low SHDN) function that may be used to disable the device, thereby reducing the supply current to 0.1µA. During shutdown, all transmit/receive functions are disabled. This line driver is widely used in application such as computers, peripherals modems, printers, instruments etc.
