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 highspeed bipolar circuitry. This allows for transmission rates up to 200 kB/s, yet minimizes the quiescent power supply current to under 5 mA. The ADM232A is a pin-compatible, high-speed upgrade for the AD232 and for the ADM232L. It is available in 16-lead DIP and in both narrow and wide surface-mount (SOIC) packages. The ADM222 contains an additional shutdown (SHDN) function that may be used to disable the device, thereby reducing the supply current to 0.1 µA. During shutdown, all transmit/receive RS-232 OUTPUTS R1IN ADM2xx GENERAL DESCRIPTION 0.1␮F EN GND SHDN RS-232 INPUTS** (ADM242) (ADM222, ADM242) * INTERNAL 400k⍀ PULL-UP RESISTOR ON EACH TTL/CMOS INPUT ** INTERNAL 5k⍀ PULL-DOWN RESISTOR ON EACH RS-232 INPUT functions are disabled. The ADM222 is available in 18-lead 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 current 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 ADM242 is available in 18-lead DIP and in a wide surface-mount (SOIC) package. REV.
