Absolute Maximum Ratings
Pin Configurations
Stresses beyond those listed under ‘‘Absolute Maximum Ratings’’ may cause
permanent damage to the device. These are stress ratings only, an d functional
operation of the device at these or any other conditions beyond those indicated
in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliabil ity.
Note 1: Also limited by package power dissipation limit, whichever is lower.
