AC Electrical Characteristics
Note 7:
This parameter is guaranteed by design but is not tested. The bus switch contributes no propagation delay other than the RC delay of the typical ON
resistance of the switch and the 50pF load capacitance, when driven by an ideal voltage source (zero output impedance).
