Note 1:
Absolute maximum ratings are DC values beyond which the device
may be damaged or have its useful life impaired. The datasheet specifica-
tions should be met, without exception, to ensure that the system design is
reliable over its power supply, temperature, and output/input loading vari-
ables. Fairchild does not recommend operation outside datasheet specifi-
cations.
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 input must be held HIGH or LOW, it must not float.
