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.
