Notes:

1.

See test circuits and waveforms.

2.

This parameter is the calculated theoretical RC time constant of ON-state resistance of the switch and the

specified load capacitance when driven by an ideal voltage source (zero source impedance). This time-constant is

of the order of 0.25ns for VS3V125. Since this time-constant is much smaller than rise/fall times of typical driving

signals, it adds very little propagation delay to the system.

3.

This parameter is guaranteed, but not production tested.
