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.

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.

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) func-

tion that may be used to disable the device, thereby reducing the

supply current to 0.1 µA. During shutdown, all transmit/receive

CMOS RS-232 Drivers/Receivers

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 dis-

abled 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.
