(3) The bus 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. This time constant is
much smaller than the rise/fall times of typical driving signals, therefore the
time 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 the switch interactions with the load on the
driven side.
