NOTES

1Stresses above 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 device reliability.
