GENERAL DESCRIPTION
The ADM560/ADM561 are four driver/five receiver interface devices designed to meet the EIA-232 standard and operate with a single +3.3 V power supply. The devices feature an on-board dc-to-dc converter, eliminating the need for dual ±5 V power supplies. This dc-to-dc converter contains a voltage doubler and voltage inverter, both of which internally generate ±6.6 V from the input +3.3 V power supply.

FEATURES
    RS-232 compatible
    Operates with 3 V or 5 V logic
    Ultralow power CMOS: 1.3 mA operation
    Low power shutdown: 0.2 μA
    Suitable for serial port mice
    116 kbps data rate
    1 μF charge pump capacitors
    Single +3 V to +3.6 V power supply
    Two receivers active in shutdown (ADM560)

APPLICATIONS
    Notebook computers
    Peripherals
    Modems
    Printers
    Battery-operated equipment
