Stresses above these ratings may cause permanent damage. Exposure to absolute maximum conditions for extended periods may

degrade device reliability. These are stress ratings only, and functional operation of the device at these or any other conditions beyond

those specified is not implied. These are stress ratings only and functional operation of the device at these or any other conditions

beyond those specified in the Electrical Characteristics Table is not implied.
