Absolute Maximum Ratings
Absolute Maximum Ratings (AMR) are stress ratings only. AMR corresponds to the maximum value that can be applied without leading
to instantaneous or very short-term unrecoverable hard failure (destructive breakdown). Stresses beyond those listed under AMR may
cause permanent damage to the device.
Functional operation of the device at these or any other conditions beyond those indicated under “Recommended Operating Range” is
not implied. Exposure to absolute-maximum-rated conditions for extended periods may adversely affect device reliability.
Device functional operating limits and guaranteed performance specifications are given under Electrical Characteristics at the test
conditions specified.
