Notes:

4.

Stresses greater than those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and

functional operation of the device at these or any other conditions beyond those indicated under “Recommended Operating Conditions” is not implied.

Exposure to “Absolute Maximum Ratings” for extended periods may affect device reliability.

5. This input current will only exist when the voltage at any of the input leads is driven negative. It is due to the collector-base junction of the input PNP

transistors becoming forward biased and thereby acting as input diode clamps. In addition to this diode action, there is also lateral NPN parasitic transistor

action on the IC chip. This transistor action can cause the output voltages of the comparators to go to the V+ voltage level (or to ground for a large

overdrive) for the time duration that an input is driven negative. This is not destructive and normal output states will re-establish when the input voltage,

which was negative, again returns to a value greater than -0.3 VDC (at +25°C).
