PI3B3125 Switching Characteristics over Operating Range
PI3B3126 Switching Characteristics over 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.
