Recommended Operating

Conditions

Note 2: 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 for AC

Note 3: All outputs loaded; thresholds on input associated with output under test.

Note 4: Maximum test duration 2.0 ms, one output loaded at a time.
