Note 1: Absolute maximum ratings are DC values beyond which the device may be damaged or have its useful life imp ai red. The dat ashee t speci ficati on s should be m et, without exception, to ensure that the system design is reliable over its power supply, temperature, and output/input loading variables. Fairchild does not recommend oper­ation outside datasheet specifications.
Note 2: The input and output negative voltage ratings may be exceeded if the input and output diode current ratings are observed.
Note 3: Control inputs must be held HIGH or LOW, they must not float.
