AC Paramters 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 tables of ‘‘Recommended Operating Conditions’’ and ‘‘Electrical Characteristics’’ provide conditions for actual device
operation
