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 on input associated with output under test.

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

Note 4: Plastic DIP package

Note 5: Max number of outputs defined as (n). Data inputs are 0V to 3V. One output @ GND.

Note 6: Max number of data inputs (n) switching. (n
