AC Electrical Characteristics
Note 8:
This parameter is guaranteed by design but 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).
Capacitance
(Note 9)
Note 9:
Capacitance is characterized but not tested.
Undershoot Characteristic
(Note 10)
Note 10:
This test is intended to characterize the device
’
s protective capabilities by maintaining output signal integrity during an input transient voltage
undershoot event.
