Absolute Maximum Ratings
Stresses above the ratings listed below can cause permanent damage to the 5V41235. 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.
