ABSOLUTE MAXIMUM RATINGS
These are stress ratings only and functional operation
of the device at these 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.
