open-in-new Find other Analog switches/muxes

Description

The CD405xB-Q1 analog multiplexers and demuliplexers 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.
