Description
These devices consist of two independent low
voltage comparators designed specifically to
operate from a single supply over a wide range of
voltages. Operation from split power supplies is
also possible.
Pin connections (top view)

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 VCC can cause excessive heating and potential destruction. The maximum output current
is approximately 20 mA independent of the magnitude of VCC+.
2. Short-circuits can cause excessive heating and destructive dissipation. 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. The input common-mode voltage of either input signal voltage should not be allowed to go negative by more than 0.3 V.
The high end of the common-mode voltage range is VCC+ -1.5 V, but either or both inputs can go to +30 V without damage.

1. At output switch point, Vo ≈ 1.4 V, Rs = 0 with VCC+ from 5 V to 30 V, and over the full common-mode range (0 V to
VCC+ -1.5 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 response time specified is for a 100 mV input step with 5 mV overdrive. For larger overdrive signals 300 ns can be
obtained.
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).
