Switching Characteristics over 2.5V Operating Range
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.
