Note (2): 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 “Electrical Characteristics” table defines the conditions for actual
device operation. Exposure to absolute maximum rated conditions for extended periods may affect device reliability.
Note (3): Not to exceed the maximum junction temperature of the IC, which relates to the operating power of the IC and the
thermal resistance of the IC/package as above
Note (4): Still air, low effective thermal conductivity board per JESD51-3.
