ABSOLUTE MAXIMUM RATINGS
(TA = 25°C unless otherwise noted.)
These are stress ratings only and functional operation of the device
at these 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.
