Note 1

Absolute Maximum Ratings indicate limits beyond which damage to the device may occur Operating Ratings indicate conditions for which the device is

functional These ratings do not guarantee specific performance limits however For guaranteed specifications and test conditions see the Electrical Characteris-

tics The guaranteed specifications apply only for the test conditions listed Some performance characteristics may degrade when the device is not operated under

the listed test conditions
