NOTE 1: In addition to the absolute maximum rating of +18V, the input voltage must not exceed 24V- - VOUT. NOTE 2: The input rating may be exceeded if the input current is limited to 1mA or less. Stresses beyond 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 in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.

The algebraic convention, whereby the most negative value is a minimum and the most positive a maximum, is used in this table. Negative current shall be defined as conventional current flow out of a device terminal. NOTE 4: Guaranteed by correlation with dc pulse measurements. NOTE 5: The parameter is guaranteed by design, but not tested.
