Stresses beyond those listed under “Absolute Maximum Ratings” may 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 indicated in the operational sections of the specifications is not implied.
Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
