_C
Functional operation above the stresses listed in the Recommended Operating Ranges is not implied. Extended exposure to stresses beyond
the Recommended Operating Ranges limits may affect device reliability.
4. Inserting a high-valued capacitor and a low-valued capacitor in parallel between V
DD
and V
SS
is recommended. In this case, the small-valued
capacitor should be at least 0.1 mF, and is mounted near the LSI.
