The CD4051B is a digitally-controlled analog multiplexer/demultiplexer having a very low ON impedance and very low OFF leakage current. This is an 8-channel analog multiplexer/Demutiplexer and it has three digital control inputs.
Diodes Incorporated extends its passive multiplexer/demultiplexer(mux/demux) switches range with the introduction of PI2DBS16212A, a 4-to-2 differential channel switching IC with up to 20Gbps data rates.
The CD4052 is a 4-Channel Multiplexer and Demulitplexer IC. It can either be used as a 4:1 Multiplexer or 1:4 Demultiplexer. The IC supports both Analog and Digital voltages and hence widely used in many designs.
