Notes:
1.
Stresses beyond those listed under Absolute Maximum Ratings might cause permanent damage to the device. These are stress ratings only,
and functional operation of the device at these or any other conditions beyond those listed under Operating Conditions is not implied.
Exposure to Absolute Maximum Ratings conditions for extended periods of time might affect device reliability.
