Description
This family of devices consists of four
independent precision-voltage comparators with
an offset voltage specification as low as 2 mV
maximum for LM339A, LM239A and LM139A.
Each comparator has been 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
characteristic in that the input common mode
voltage range includes ground even though
operated from a single power supply voltage.

2. Short-circuits can cause excessive heating. These values are typical.
3. Human body model: a 100 pF capacitor is charged to the specified voltage, then discharged through a
1.5 kΩ resistor between two pins of the device. This is done for all couples of connected pin combinations
while the other pins are floating.
4. Machine model: a 200 pF capacitor is charged to the specified voltage, then discharged directly between
two pins of the device with no external series resistor (internal resistor < 5 Ω). This is done for all couples of
connected pin combinations while the other pins are floating.
5. Charged device model: all pins and the package are charged together to the specified voltage and then
discharged directly to the ground through only one pin. This is done for all pins.

1. At output switch point, Vo ≈ 1.4 V, V
2. 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.
3. The input common-mode voltage of either input signal voltage should not be allowed to go negative by more than 0.3 V.
The upper end of the common-mode voltage range is V
damage.
4. 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
-0.3 V (or 0.3 V below the negative power supply, if used).
5. The response time specified is for a 100 mV input step with 5 mV overdrive. For larger overdrive signals, 300 ns can be
obtained.
