Note:
Stresses greater than those listed under MAXIMUM
RATINGS may cause permanent damage to the de-
vice. This is a stress rating only and functional op-
eration 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 af-
fect reliability.
