CMOS ANALOG MULTIPLEXERS/DEMULTIPLEXERS

APPLICATION INFORMATION
In applications where separate power sources drive VDD and the signal inputs, the VDD current capability should
exceed VDD/RL (RL = effective external load). This provision avoids permanent current flow or clamp action on the
VDD supply when power is applied or removed from the CD4051B, CD4052B, or CD4053B.
