Stresses beyond those listed under
absolute maximum ratings
may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those ndicated under
recommended operating conditions
s not mplied.
Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTE 1: The package thermal impedance is calculated in accordance with JESD 51-7.
