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.

1. At output switch point, VO ≈ 1.4 V, RS = 0 with V mode range (0 V to 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 there is no load on the reference of input lines

3. The response time specified is for a 100 mV input step with 5 mV overdrive.

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. Maximum values are guaranteed by design.
