Note 2: Absolute Maximum Ratings are values beyond which the device
may be damaged or have its useful life impaired. The databook 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 databook specifica-
tions.
Note 3: HIGH or LOW state. IOUT absolute maximum rating must be
observed.
Note 4: When outputs are in OFF-STATE or when VCC OV.
Note 5: VOUT  GND, VOUT ! VCC (Outputs Active).
Note 6: Unused inputs must be held HIGH or LOW. They may not float.
