CC

–1.5V).
The direction of the input current is out of the IC due to the PNP input stage. This current is essentially constant, independent of the state of the
output, so no loading charge exists on the reference of input lines
The input common-mode voltage of either input signal voltage should not be allowed to go negative by more than 0.3V. The upper end of the
common-mode voltage range is V
CC
Positive excursions of input voltage may exceed the power supply level. As long as the other voltage remains within the common-mode range, the
comparator will provide a proper output state.
The low input voltage state must not be less than –0.3V (or 0.3V below the negative power supply, if used)
The response time specified is for a 100mV input step with 5mV overdrive.
Maximum values are guaranteed by design & evaluation.
