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.

1. Short-circuits from the output to V
CC+
can cause excessive heating and eventual destruction. The
maximum output current is approximately 20 mA independent of the magnitude of V
CC+
.
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.
