Maximum Ratings
Important Note: The Absolute Maximum Ratings, Table 32, are stress ratings only, and functional operation of the
device at conditions other than those indicated in the Operating Conditions sections of this specification are not
implied. Exposure to the absolute maximum ratings for an extended period may reduce the reliability or useful lifetime
of the product.
