Maximum Ratings

(Above which the useful life may be impaired. For user guidelines, not tested.)

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 opera-

tion 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 reliability.
