Description

The CD4051B-Q1 analog multiplexers and demultiplexers are digitally-controlled analog switches having low ON impedance and very low OFF leakage current. These multiplexer circuits dissipate extremely low quiescent power over the full VDD – VSS and VDD – VEE supply-voltage ranges, independent of the logic state of the control signals.
