Note: Stresses above 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 above those
indicated in the operation sections of the specifications is not implied.
Exposure to Absolute Maximum Ratings conditions for extended periods may affect device reliability.
