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 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

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

AN-90

Typical Application

TLF5905 – 5
