ABSOLUTE MAXIMUM RATINGS
These are stress ratings only, and functional operation of
the device at these ratings or any other above those
indicated in the operation sections of the specifications
below is not implied. Exposure to absolute maximum rating
conditions for extended periods of time may affect
reliability.
