Note:

Stresses at or above 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 these or any other condi-

tions above those indicated in the operational

sections of this specification is not implied. Exposure

to absolute maximum rating conditions may affect

device reliability.
