CD4051

The CD4051B is a single 8-channel analog multiplexer/demultiplexer. It is a digitally-controlled analog switch that allows the input signal to be selected from one of eight sources and routed to the output. This IC can handle both analog and digital signals, making it suitable for a variety of applications in signal routing and multiplexing. It operates over a wide voltage range and provides high noise immunity.
