Notes: 5. Limits over the full temperature are guaranteed by design, but not tested in production . 6. Over the full input common-mode range 0V to VCC-1.5V (at +25°C). 7. 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 VCC-1.5V (at +25°C), but either or both inputs can go to +36V without damages , independent of the magnitude of the VCC.
