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 and cause

permanent damage to the device.
