AC Electrical Characteristics

Note 6: This parameter is guaranteed. 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.
