NOTE:

Stress 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 greater than those indicated in the

operational sections of this specification is not implied. Exposure to absolute maximum

rating conditions for extended periods may affect reliability.
