AbSoLUTE MAxiMUM RATingS
This is a stress rating only and functional operation of
the device at these ratings or any other above those
indicated in the operation section of the specification
is not implied. Exposure to absolute maximum ratings
conditions for extended periods of time may affect re-
liability.
