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:
Capacitance is guaranteed by periodic testing.
Note 3:
C
PD
determines the no load AC power consumption of any CMOS device. For complete explanation see 54C/74C Family Characteristics application note
