Note 1: Absolute Maximum Ratings indicate limits beyond which damage to
the device may occur. Recommended operating conditions indicate condi-
tions for which the device is intended to be functional, but do not guarantee
specific performance limits. For guaranteed specifications and test condi-
tions, see the Electrical Characteristics. The guaranteed specifications apply
only for the test conditions listed.
