AC Electrical Characteristics

Note 6: 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 the source (zero output impedance).

Note 8: This test is intended to characterize the device’s protective capabilities by maintaining output signal integrity during an input transient voltage

undershoot event.
