Electrical Characteristics for the applicable device type.
(2) Specified by design
(3) The bus switch contributes no propagation 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 0.25 ns for 10-pF load. This time constant is much smaller than
the rise/fall times of typical driving signals, therefore the time adds very little
propagation delay to the system. Propagation 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
interactions with the load on the driven side.
