Recommended Operating

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 circuits outside databook specifications.

Note 3: Unused inputs must be held HIGH or LOW. They may not float.
