AC Parameters are guaranteed by DC correlated testing.
Note 1:
‘‘Absolute Maximum Ratings’’ are those values beyond which the safety of the device cannot be guaranteed. Except for ‘‘Operating Temperature Range’’
they are not meant to imply that the devices should be operated at these limits. The table of ‘‘Electrical Characteristics’’ provides conditions for actual device
operation.
Note 2:

0V unless otherwise specified.
Note 3:
I
OL
and I
OH
are tested one output at a time.
Note 4:
If more than one unit is cascaded t
rCL
should be made less than or equal to the fixed propagation delay of the output of the driving stage for the estimated
capacitive load.
Note 5:
C
PD
determines the no load AC power consumption of any CMOS device. For complete explanation, see 54C/74C family characteristics application note
AN-90.
Note 6:
Setup times are measured with reference to clock and a fixed hold time (t
H
) as specified.
