Notes:

1. Measurements are standardized against short-circuit at all terminals.

2. Off-isolation is measured between COMx and the off NCx/NOx terminal of each switch. Off-isolation =

20log(VOUT/VIN).

3. Crosstalk is measured from one channel to all other channels.

4. Signal direction through the switch is reversed; worst values are recorded.
