Notes: test circuit waveforms. This parameter guaranteed tested Propagation Delays. switch contributes propagational delay other than delay resistance switch load capacitance. time constant switch alone order 0.25ns 50pF load. Since this time constant much smaller than rise/fall times typical driving signals, adds very little propagational delay system. Propagational delay switch when used system determined driving circuit driving side switch interaction with load driven side.
