GENERAL DESCRIPTION

The ADM222, ADM232A, ADM242 are a family of high-speed RS-232 line drivers/receivers offering transmission rates up to 200 kB/s. Operating from a single 5 V power supply, a highly efficient on-chip charge pump using small (0.1 µF) external capacitors allows RS-232 bipolar levels to be developed. Two RS-232 drivers and two RS-232 receivers are provided on each device.
