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.
