Notes: 5. Limits over the full temperature are guaranteed by design, but not tested in production. 6. The input common-mode voltage of either input signal voltage should not be allowed to go negatively by more than 0.3V (at +25°C). The upper end of the common-mode voltage range is V CC -1.5V (at +25°C), but either or both inputs can go to +36V without damages, independent of the magnitude of the VCC.
