ADM242AN Product Details

The ADM222, ADM232A, ADM242AN are a family of high-speedRS-232 line drivers/receivers offering transmission rates up to200 kB/s. Operating from a single 5 V power supply, a highlyefficient on-chip charge pump using small (0.1 µF) externalcapacitors allows RS-232 bipolar levels to be developed. TwoRS-232 drivers and two RS-232 receivers are provided oneach device.

The devices are fabricated on BiCMOS, an advanced mixedtechnology process that combines low power CMOS with highspeedbipolar circuitry. This allows for transmission rates up to200 kB/s, yet minimizes the quiescent power supply current tounder 5 mA.

The ADM232A is a pin-compatible, high-speed upgrade for theAD232 and for the ADM232L. It is available in 16-lead DIPand in both narrow and wide surface-mount (SOIC) packages.

The ADM222 contains an additional shutdown (SHDN) functionthat may be used to disable the device, thereby reducing thesupply current to 0.1 µA. During shutdown, all transmit/receivefunctions are disabled. The ADM222 is available in 18-leadDIP and in a wide surface-mount (SOIC) package.

The ADM242AN combines both shutdown (SHDN) and enable(EN) functions. The shutdown function reduces the supplycurrent to 0.1 mA. During shutdown, the transmitters are disabledbut the receivers continue to operate normally. Theenable function allows the receiver outputs to be disabledthereby facilitating sharing a common bus. The ADM242AN isavailable in 18-lead DIP and in a wide surface-mount (SOIC)package.
