Note 1: All voltages are measured with respect to the ground pin, unless otherwise specified.
Note 2: Absolute Maximum Ratings indicate limits beyond which damage may occur. Operating Ratings indicate
conditions for which the device is functional, but do not guarantee specific performance limits. Electrical
Characteristics state DC and AC electrical specifications under particular test conditions which guarantee
specific performance limits. This assumes that the device is within the Operating Ratings. Specifications are
not guaranteed for parameters where no limit is given, however, the typical value is a good indication of
