Absolute Maximum Ratings indicate limits beyond which damage to the component may occur. Operating Ratings are conditions under

which operation of the device is guaranteed. Operating Ratings do not imply guaranteed performance limits. For guaranteed

performance limits and associated test conditions, see the Electrical Characteristics tables.
