Absolute Maximum Ratings

Stress greater than those listed under “Absolute Maximum Ratings” may cause permanent damage to the

device. These stress ratings only, and functional operation of the device at these or any conditions beyond

those indicated under recommended Operating Conditions is not implied. Exposure to “Absolute Maximum

Rating” for extended periods may affect device reliability. Use of standard ESD handling precautions is

required.
