Notes:
1. For max. or min. conditions, use appropriate value specified under Electrical Characteristics for the applicable device type.
2. Guaranteed by design.
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 10pF 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 interactions with the load on the driven side.

3. Measured by the voltage drop between A and B pins at indicated current through the switch. ON-resistance is determined by the lower of the
voltages on the two (A & B) pins.
4. This parameter is determined by device characterization but is not production tested.
