Notes:
1. See test circuit and waveforms.
2. This parameter is guaranteed but not tested on Propagation Delays.
3. The switch contributes no propagational delay other than the RC delay of the ON resistance of the switch and the load capacitance. The time
constant for the switch alone is of the order of 0.30ns for 10pF load. Since this time constant is much smaller than the rise/fall times of typical
driving signals, it adds very little propagational delay to the system. Propagational delay of the switch when used in a system is determined by
the driving circuit on the driving side of the switch and its interaction with the load on the driven side.
