(1) For Maximum or Minimum conditions, use the appropriate value specified under 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 0.25 ns for 10-pF load. The time constraint adds very little propagational delay to the system because it 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 its interactions with the load on the driven side.
