Absolute Maximum Ratings(Note 2)

Recommended Operating

Conditions (Note 6)

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.
