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

CD4066BMCD4066BC bilateral switches) This provision

avoids any permanent current flow or clamp action of the

VDD supply when power is applied or removed from

CD4066BMCD4066BC

In certain applications the external load-resistor current

may include both VDD and signal-line components To avoid

drawing VDD current when switch current flows into termi-

nals 1 4 8 or 11 the voltage drop across the bidirectional

switch must not exceed 06V at TAs25 C or 04V 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
