Description
The NJM339C consist of four independent low power voltage comparators
designed specifically to operate from a single supply over a wide range of
voltages. Operation from split power supplies is also possible.
These comparators also have a unique characteristic in that the input
common-mode voltage range includes ground even though operated from a
single power supply voltage.

1. Input voltage is the voltage should be allowed to apply to the input terminal independent of the magnitude of V
CC+
.
2. Output voltage is the voltage should be allowed to apply to the output terminal independent of the magnitude of V
CC+
.
3. Short-circuits from the output to V
CC+
can cause excessive heating and potential destruction
4. Short-circuit can cause excessive heating and destructive dissipation. Values are typical.

2. The direction of the input current is out of the IC due to the PNP input stage.
3. 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 must not be less than –0.3V (or 0.3V below the negative power supply, if used).
4. The response time specified is for a 100mV input step with 5mV overdrive.
5. This parameter is not 100% test.
