CD4051 Analog Multiplexer

The CD4051 is a digitally-controlled analog multiplexer and demultiplexer IC. It features eight independent input/output channels and one common channel, allowing you to select one of the eight inputs using three binary control pins (A, B, C). This component is widely used to expand the analog input capabilities of microcontrollers, allowing a single ADC pin to read from multiple sensors. It operates over a wide voltage range, making it compatible with both 3.3V and 5V logic systems. Key features include low ON resistance, wide analog signal range, and low power consumption. It is commonly used in data acquisition systems, audio signal routing, and automated test equipment. Choose this component for reliable signal routing in your DIY electronics projects and prototypes.
