Absolute Maximum Ratings

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to

the device. These are stress ratings only. Functional operation of the device at these or any other

conditions beyond those indicated under “Operating Conditions” is not implied. Exposure to absolute

maximum rating conditions for extended periods may affect device reliability.
