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 the specification is

not implied. Exposure to any absolute maximum rating for extended

periods may affect device performance and reliability. Devices are

ESD

sensitive.

Handling

precautions

are

recommended.
