Exposure of the device under conditions beyond the limits specified by Maximum Ratings for extended periods may cause permanent damage to the

device and affect product reliability. These conditions represent a stress rating only, and functional operations of the device at these or any other

conditions above the operational limits noted in this specification is not implied.

* Note: Operating Temperature is guaranteed by design for all parts (COMMERCIAL and INDUSTRIAL), but tested for INDUSTRIAL grade only.
