The CD405xB 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 V_DD – V_SS and V_DD – V_EE supply-voltage ranges, independent of the logic state of the control signals.
