*Stresses greater than those listed under “Absolute Maxi-

mum Ratings” may cause permanent damage to the de-

vice. 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 condi-

tions for extended periods may affect reliability.
