“Absolute Maximum Ratings” indicate limits beyond which damage to the device may occur, including inoperability and degradation of
device reliability and/or performance. Functional operation of the device and/or non-degradation at the Absolute Maximum
RatingsRatings or other conditions beyond those indicated in the Recommended Operating Conditions is not implied. The
Recommended Operating Conditions indicate conditions at which the device is functional and the device should not be operated beyond
such conditions. All voltages are measured with respect to the ground pin, unless otherwise specified
