Nice Cd4051 Circuit Diagram

Cd4052 is a dual 4 channel differential multiplexer demultiplexer ic which has two binary control inputs a and b.

Cd4051 circuit diagram. Programmable logic circuits sensors 3 description the cd405xb analog multiplexers and demultiplexers are digitally controlled analog switches having low on impedance and very low off leakage current. The two binary input signals a and b are responsible for selecting channels that which channel should be turned on. In multiplexer mode it takes 4 inputs from 4 channels and returns the output on channel x y.
