ELECTRICAL CHARACTERISTICS

Stresses beyond these listed under "Absolute Maximum

Ratings" may cause permanent damage to the device. These

are stress ratings only, and functional operation of the de-

vice at these or any other conditions beyond those indi-

cated in the operational sections of the specifications is

not implied. Exposure to absolute maximum rating condi-

tions for extended periods may affect device reliability.
