FIGURE 23. TYPICAL TIME-DIVISION APPLICATION OF THE CD4052B
Special Considerations
In applications where separate power sources are used to
drive V
DD
and the signal inputs, the V
DD
current capability
should exceed V
DD
/R
L
(R
L
= effective external load). This
provision avoids permanent current flow or clamp action on
the V
DD
supply when power is applied or removed from the
CD4051B, CD4052B or CD4053B.
