Comments
Stresses above those listed under "Absolute
Maximum Ratings" may cause permanent damage to
this device. These are stress ratings only. Functional
operation of this device at these or any other
conditions above those indicated in the operational
sections of this specification is not implied or
intended. Exposure to the absolute maximum rating
conditions for extended periods may affect device
reliability.
