Recommended Operating
Conditions
Note 1: Absolute maximum ratings are values beyond which the device
may be damaged or have its useful life impaired. The databook specifica-
tions should be met, without exception, to ensure that the system design is
reliable over its power supply, temperature, and output/input loading vari-
ables. Fairchild does not recommended operation outside data book speci-
fications.
Note 2: Unused inputs must be used HIGH or LOW. They may not float.
Note 3: The maximum allowable values of Cx and Rx are a function of the
leakage of capacitor Cx, the leakage of the device, and leakage due to
board layout and surface resistance.
Susceptibility to externally induced noise signals may occur for Rx 1 M .
