Working Principles

The 74HC4067BQ-Q100J is a CMOS analog multiplexer/demultiplexer IC. It uses control signals (S0-S3) to select one of the 16 input channels and routes it to the output pin (Y0-Y15). The E pin enables or disables the IC, while the Z pin serves as a common input/output terminal.

When a specific channel is selected, the corresponding Y pin connects to the Z pin, allowing the signal to pass through. The on-state resistance ensures minimal signal distortion during transmission.
