SCOPE

AND FIXTURE

Note a:

Stresses greater than those listed under “Absolute Maximum

Ratings” may cause permanent damage to the device. This is a

stress rating only, and functional operation of the device at condi-

tions above those indicated in the operational sections of this

specification is not implied. Exposure to absolute maximum rat-

ing conditions for extended periods may affect reliability.
