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: All voltage values are with respect to the network ground terminal.
