AC Electrical Characteristics (Note 2)
TA = 25°C, CL = 50 pF, unless otherwise specified
Note 2: AC Parameters are guaranteed by DC correlated testing.
Note 3: Capacitance is guaranteed by periodic testing.
Note 4: CPD determines the no load AC power consumption of any CMOS device. For complete explanation, see Family Characteristics Application Note—
AN-90.
