Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is

functional, but do not guaranteed specific performance limits. For guaranteed specifications and test conditions, see, the Electrical Characteristics. The guaranteed

specifications apply only for the test conditions listed. Some performance characteristics may degrade when the device is not operated under the listed test

conditions.

Note 3: 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

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

are allowed to saturate.

Note 5: 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 outputso

no loading change exists on the reference or input lines.

Note 7: Positive excursions of input voltage may exceed the power supply level. As long as the other voltage remains within the common-mode range, the

supply, if used) (at 25˚C).
