ABSOLUTE MAXIMUM RATINGS

This is a stress rating only and functional operation of the device at

these or any other conditions above those indicated in the operation

sections of this specification is not implied. Exposure to absolute

maximum rating conditions for extended periods of time may affect

reliability.
