These are stress ratings only and functional
operation of the device at these ratings or
any other above those indicated in the opera-
tion sections of the specifications below is not
implied. Exposure to absolute maximum rating
conditions for extended periods of time may
affect reliability.
NOTE 1: V+ and V- can have maximum
magnitudes of 7V, but their absolute difference
cannot exceed 13V.
