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.
