CD4051 Single 8-Channel Analog Multiplexer/Demultiplexer IC DIP-16 (CD4051 DIP IC)
The CD4051 is a CMOS single 8-channel analog multiplexer and demultiplexer IC that allows one of eight analog or digital input channels to be selected and connected to a common output. It uses three binary select inputs to control which channel is active at any given time.
This IC is widely used in analog signal routing, data acquisition systems, audio switching, and sensor multiplexing applications where multiple analog signals need to be switched through a single channel. It supports bidirectional signal flow making it suitable for both multiplexing and demultiplexing operations in electronics projects.
