DESCRIPTION
These devices consist of fourindependentprecision
voltage comparators with an offset voltage specifi-
cations as low as 2mV max for LM339A, LM239A
and LM139A. All these comparators were designed
specifically to operate from a single power supply
over a wide range of voltages. Operation from split
power supplies is also possible.
These comparators also have a unique characteris-
tic in that the input common-mode voltage range
includes ground even though operatedfrom a single
power supply voltage.

from 5Vto 30V, and over the full input common-mode range
(0V to V
CC
+
–1.5V).
3. The direction of the input current is out of the IC due to the PNP input stage. This current is essentially con-
stant, independent of the state of the output, so no loading charge exists on the reference of input lines.
4. The input common-mode voltage of either input signal voltage should not be allowed to go negati ve by more
than 0.3V. The upper end of the common-mode voltage range is V
CC
+
–1.5V, but either or both inputs can go
to +30V without damage.
5. The response time specified is for a 100mV input step with 5mV overdrive. For larger overdrive signals 300ns
can be obtained.
6. 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 bellow the negative power supply, i f used).
