Description
This device consists of four independent precision
voltage comparators. All these comparators are
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-circuit from the output to V
output current is approximately 20 mA, independent of the magnitude of V
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.
