Absolute Maximum Ratings
These are stress ratings only and functional opera-
tion of the device at these ratings or any other above
those indicated in the operation sections of the speci-
fications below is not implied. Exposure to absolute
maximum rating conditions for extended periods of
time may affect reliability.
