Notes:

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 0.25ns 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.
