Table 2. Absolute Maximum Ratingsa
a. 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.
