The ADM242ARZ is a high-speed Line Driver/Receiver offering transmission rates up to 200kB/s. Operating from a single 5V power supply, a highly efficient on-chip charge pump using small (0.1μF) 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 device is 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 200kB/s, yet minimizes the quiescent power supply current to under 5mA. The ADM242 combines both shutdown (SHDN) and enable (EN) functions. The shutdown function reduces the supply current to 0.1mA. During shutdown, the transmitters are disabled but the receiver continues to operate normally. The enable function allows the receiver outputs to be disabled thereby facilitating sharing a common bus.
