These are stress ratings only, and functional op eration of the device at th ese 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 -0.3 V DC (at 25oC).

Note 3: These specificati ons are limited to -40 oC≤ TA ≤85oC. Limits over temperatur e are guaranteed by design, but not tested in production. Note 4: The input common-mode voltage of either input signal voltage should not be allowed to go negatively by more than 0.3V (at 25oC). The upper end of the common-mode voltage range is V CC-1.5V (at 25oC), but either or both inputs can go to +18V without damages, independent of the magnitude of the VCC.
