Absolute Maximum Ratings
CAUTION: Absolute Maximum ratings are stress ratings only. Functional operation beyond recommended operating
conditions is not implied. Stress beyond absolute maximum ratings may cause permanent damage to the device.
Exposure to absolute maximum rated conditions for extended periods may affect device reliability.
