Recommended Operating

Conditions

Note 1: Absolute maximum ratings are those values beyond which damage

to the device may occur. The databook specifications should be met, with-

out exception to ensure that the system design is reliable over its power

supply, temperature, and output/input loading variables. Fairchild does not

recommend operation of FACT

¥ circuits outside databook specifications.

DC Electrical Characteristics

Note 2: All outputs loaded; thresholds associated with output under test.

Note 3: Maximum test duration 2.0 ms; one output loaded at a time.

Note 4: Worst case package.

Note 5: Maximum number of outputs that can switch simultaneously is n. (n

 1) outputs are switched LOW and one output held LOW.

Note 6: Maximum number of outputs that can switch simultaneously is n. (n

 1) outputs are switched HIGH and one output held HIGH.

Note 7: Maximum number of data inputs (n) switching. (n
