*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.
