Absolute Maximum Ratings(Note 4)
Recommended Operating
Conditions (Note 6)
Note 4: The Absolute Maximum Ratings are those values beyond which
the safety of the device cannot be guaranteed. The device should not be
operated at these limits. The parametric values defined in the Electrical
Characteristics tables are not guaranteed at the Absolute Maximum Rat-
ings. The “Recommended Operating Conditions” table will define the condi-
tions for actual device operation.
Note 5: IO Absolute Maximum Rating must be observed.
Note 6: Floating or unused inputs must be held HIGH or LOW.
