Notes:

1. See test circuit and waveforms.

2. This parameter is guaranteed but not tested on Propagation Delays.

3. ThebusswitchcontributesnopropagationaldelayotherthantheRCdelayoftheONresistance

of the switch and the load capacitance. The time constant for the switch alone is of the order

of0.25nsfor50pFload.Sincethistimeconstantismuchsmallerthantherise/falltimesoftypical

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.
