note 1 : Applied for Vcc_xxx except for Vcc_core .
note 2 : Applied for Vcc_core only.
note 3 : The clamping voltage of the trigger pulse power source should be below a value of Vte.
Note: Stresses above those listed may cause permanent damage to system components. These
are stress ratings only. Functional operation at these or any conditions above those indicated in the
operational sections of this specification is not implied. Exposure to absolute maximum rating
conditions for extended periods may affect system reliability.
