Note 1: Stresses greater than those 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

beyond those indicated under “Recommended Operating Conditions” is not implied. Exposure to “Absolute

Maximum Ratings” for extended periods may affect device reliability.

Note 2: Devices are ESD sensitive. Handling precaution recommended.
