AC Electrical Characteristics (Note 4)
TA = 25°C, CL = 50 pF, RL = 200k, Input trCL = tfCL = 20 ns, unless otherwise specified
Note 4: *AC Parameters are guaranteed by DC correlated testing.
Note 5: CPD determines the no load AC power consumption of any CMOS device. For complete explanation, see 74C Family Characteristics application
note, AN-90.
