Parameters
This parameter is guaranteed but not tested on Propagation Delays.
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 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.
