capacitance. The time constant for the switch alone is of the order of 0.25ns for 50pF 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 bus
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.
