Absolute Maximum Ratings
(Note 1)
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 driven 0V to 3V. One output @ GND.
Note 6:
Max number of Data Inputs (n) switching. (n
