Special Considerations
In applications where separate power sources are used to
drive VDD and the signal input the VDD current capability
should exceed VDD RL (RLeeffective external load of the 4
CD4066BM CD4066BC bilateral switches) This provision
avoids any permanent current flow or clamp action of the
VDD supply when power is applied or removed from
CD4066BM CD4066BC
In certain applications the external load-resistor current
may include both VDD and signal-line components To avoid

nals 1 4 8 or 11 the voltage drop across the bidirectional
switch must not exceed 0 6V at TAs25 C or 0 4V at
TAl25 C (calculated from RON values shown)
No VDD current will flow through RL if the switch current
flows into terminals 2 3 9 or 10
