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 (RL = effective external load of the 4

CD4066BC bilateral switches). This provision avoids any

permanent current flow or clamp action of the VDD supply

when power is applied or removed from CD4066BC.

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

terminals 1, 4, 8 or 11, the voltage drop across the

bidirectional switch must not exceed 0.6V at TA ≤ 25°C, or

0.4V at TA > 25°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.
