11 / 17 page CD4066B-Q1 www.ti.com SCHS383 – APRIL 2011 APPLICATION INFORMATION In applications that employ separate power sources to drive VDD and the signal inputs, the VDD current capability should exceed VDD/RL (RL = effective external load of the four CD4066B-Q1 bilateral switches). This provision avoids any permanent current flow or clamp action on the VDD supply when power is applied or removed from the CD4066B-Q1. In certain applications, the external load-resistor current can 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 0.8 V (calculated from ron values shown). No VDD current will flow through RL if the switch current flows into terminals 2, 3, 9, or 10.
