Note 3: 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 Ratings. The "Recommended Operating Conditions" table will define the conditions for actual device operation. Note 4: IO Absolute Maximum Rating must be observed. Note 5: Unused inputs must be held HIGH or LOW. They may not float.
