AC Electrical Characteristics
Note 6: This parameter is guaranteed by design but not tested. The bus switch contributes no propagation delay other than the RC delay of the On Resis-
tance of the switch and the 50 pF load capacitance, when driven by an ideal voltage source (zero output impedance).
Note 7: Guaranteed by design.
