not tested in production.
Note 4: The input common mode voltage of either input signal voltage should not be allowed to go negatively by
more than 0.3V (at 25
o
C). The upper end of the common mode voltage range is V
CC
-1.5V (at 25

both inputs can go to +36V without damages, independent of the magnitude of the V

.
