Description

The ADM222 is in 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 ADM222 is  fabricated on BiCMOS, an advanced mixed technology process which 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.

The ADM222 contains an additional shutdown (SHDN) func-tion which may be used to disable the device thereby reducing the supply current to 0.1 µA. During shutdown, all transmit/ receive functions are disabled. The ADM222 is available in 18-pin DIP and in a wide surface mount (SOIC) package.The ADM242 combines both shutdown (SHDN) and enable ( EN) functions. The shutdown function reduces the supply curent to 0.1 mA. During shutdown, the transmitters are disabled but the receivers continue to operate normally. The enable function allows the receiver outputs to be disabled thereby facilitating sharing a common bus. The ADM222 is available in 18-pin DIP and in a wide surface mount (SOIC) package.
