74HC4051 8-Channel Analog Multiplexer/Demultiplexer 5V IC DIP-16
The 74HC4051 8-Channel Analog Multiplexer/Demultiplexer IC is used to select one of eight analog or digital signal channels for connection to a common input/output line in electronic circuits and control systems.
26.00 EGP
The 74HC4051 , commonly identified as the CD4051B or 4051-family analog multiplexer/demultiplexer depending on the manufacturer’s numbering, is an integrated circuit designed to switch between eight independent signal channels using digital selection inputs. Three address inputs determine which channel is connected to the common terminal, while an inhibit input can disable all channels. This functionality helps reduce the number of input/output connections required when interfacing multiple sensors, signal sources, or measurement points with a controller.
The IC can be used for analog signal routing and digital signal selection in microcontroller projects, data acquisition systems, measurement equipment, and electronic switching circuits. It is commonly available in a 16-pin DIP package for through-hole mounting, making it suitable for breadboards, prototyping, and repair work. Check the exact manufacturer’s datasheet before use, because the permitted supply voltage, input range, and pin characteristics depend on the specific 4051-family device.
Features:
- Eight-channel signal selection.
- Bidirectional analog and digital signal switching.
- Three digital address inputs for channel selection.
- Common input/output terminal for multiplexing and demultiplexing.
- Inhibit control for disabling all channels.
- Low ON-state resistance.
- Suitable for sensor interfacing and signal routing.
- DIP package for through-hole assembly.
