RS232, 2 drivers / 2 receivers, DIL-16

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.
The devices are fabricated on BiCMOS, an advanced mixed technology process that combines low power CMOS with high-speed bipolar circuitry. This allows for transmission rates up to 200 kB/s, yet minimizes the quiescent power supply current to under 5 mA.
