≤85 o
C. Limits over temperature are guaranteed by design,
but 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
o
C), but either or
both inputs can go to +36V without damages, independent of the magnitude of the V
CC
.
