Characteristics

6.1 Absolute Maximum Ratings

Stresses beyond those listed in Table 1 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 in Section 5

Electrical Characteristics is not implied.

Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
