Using BiCMOS wafer fabrication technology allows the DG9424/9425/9426 to operate on single and dual supplies. Single supply voltage ranges from 3 to 12 V while dual supply operation is recommended with "3 to "6 V. Combining high speed (tON: 42 ns), flat rDS(on) over the analog signal range ( ), minimal insertion lose ( - 3 dB at 190 MHz), and excellent crosstalk and off-isolation performance, the DG9424/9425/9426 are ideally suited for audio and video signal switching. The DG9424 and DG9425 respond to opposite control logic as shown in the Truth Table. The DG9426 has two normally open and two normally closed switches.
