Note: Stresses 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 those or any other condi-

tions, above those indicated in the operational listings

of this specification, is not implied. Exposure to maxi-

mum rating conditions for extended periods may affect

device reliability.
