Absolute Maximum Ratings (Note 1)

Note 1: 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 Max-

imum Ratings" for extended periods may affect device reliability.

Note 2: 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 -0.3V (at
