Table 2. Absolute Maximum Ratings(1)
1. Stresses above the ratings listed below can cause permanent damage to the device. These ratings are stress ratings only. Functional
operation of the device at these or any other conditions above those indicated in the operational sections of the specifications is not implied.
Exposure to absolute maximum rating conditions for extended periods can affect product reliability. Electrical parameters are guaranteed
only over the recommended operating temperature range.
