Notes:
1. See test circuit and waveforms.
2. This parameter is guaranteed but not tested on Propagation Delays.
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 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.
