AC Electrical Characteristics
Note 6: This parameter is guaranteed by design. The bus switch contributes no propagation delay other than the RC delay of the typical On Resistance of the switch and the 50
pF load capacitance, when driven by an ideal voltage source (zero output impedance). The specified limit is calculated on this basis.
