Note — The device is not guaranteed to function outside its operating
rating. Stresses listed under Absolute Maximum Ratings may cause
permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions outside
those listed in the operational sections of this specification is not implied.
Exposure to any absolute maximum rating for extended periods may
affect device performance and reliability.
* Q 14 pin SOIC; R 16 pin SSOP.
