These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under “Recommended Operating Co nditions” is not implied. Exposure to “Absolute Maximum Ratings” for extended periods may affect device reliability. Note 2: Electronic semiconductor products are sensitive to Electro Static Discharge (ESD). Always observe Electro Static Discharge control procedures whenever handling semiconductor products.
