Working Principles

The 74HCT4067BQ-Q100J operates based on the principle of multiplexing and demultiplexing. It uses control signals (S0-S3) to select one of the 16 input channels (A0-A15) and routes it to the output pin (Y). The E pin enables or disables the IC's operation. When enabled, the selected channel's signal passes through to the output pin, allowing efficient signal routing in electronic circuits.
