Note: Stresses greater than those listed under “Absolute Maximum Ratings” may cause permanent damage to the device.
This is a stress rating only, and functional operation of the device at these or any other conditions above those indicated in
the operational sections of this specification is not implied.
Exposure to absolute maximum rating conditions for extended periods may affect reliability.
