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 specifica-
tions below is not implied. Exposure to absolute maxi-
mum rating conditions for extended periods of time
may affect reliability and cause permanent damage to
the device.
