AC Parameters are guaranteed by DC correlated testing

Note 2

Capacitance is guaranteed by periodic testing

Note 3

CPD determines the no load AC power consumption of any CMOS device For complete explanation see 54C74C Family Characteristics Application Note

AN-90

Note 4

These are peak output current capabilities Continuous output current is rated at 12 mA max
