Electrical Characteristics for the applicable device type.
(2) Specified by design
(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. The time constraint adds very little
propagational delay to the system because the time is much smaller than the rise and fall
times of typical driving signals. 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.
