NOTE 1: V+ and V- can have maximum magnitudes of 7V, but their absolute dierence cannot exceed 13V.
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 specications
below is not implied. Exposure to absolute maximum
rating conditions for extended periods of time may
aect reliability and cause permanent damage to the
device.
