The DG441L/442L are low voltage pin-for-pin compatiblecompanion devices to the industry standard DG441L/442Lwith improved performanceUsing BiCMOS wafer fabrication technology allows theDG441L/442L to operate on single and dual supplies. Singlesupply voltage ranges from 3 to 12 V while dual supplyoperation is recommended with 3 to 6 V.Combining high speed (tON: 20 ns), flat rDS(on) over the analogsignal range (5
), minimal insertion lose (-3 dB at 280 MHz),and excellent crosstalk and off-isolation performance (-50 dBat 50 MHz), the DG441L/442L are ideally suited for audio andvideo signal switching.The DG441L/442L responds to opposite control logic asshown in the Truth Table. open and two normally closedswitches.
