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 they are not meant to imply that the devices
should be operated at these limits The table of ‘‘Recommended Operating Conditions’’ and ‘‘Electrical Characteristics’’ provides conditions for actual device
operation
Note 2 V_SS e 0V unless otherwise specified
Note 3 I_OH and I_OL are tested one output at a time
Note 4 C_PD determines the no load AC power consumption of any CMOS device For complete explanation see 54C 74C Family Characteristics application note
