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

Parameters Description
frequency. The I and Y inputs generate no significant AC or DC currents as they transition. This parameter is not tested, but is
guaranteed by design.
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.
