Working Principles

The MC74HC4067ADWG is a 16-channel analog multiplexer/demultiplexer IC. It operates by using the address selection inputs (S0-S3) to select one of the 16 input channels and route it to the common terminal (COM). The selected channel's output is then available at the corresponding Yx pin.

The enable input (E) and inhibit input (INH) control the operation of the IC. When E is high, the IC is enabled, and the selected channel is active. Conversely, when E is low or INH is high, the IC is disabled, and all channels are turned off.

Detailed Application Field Plans

The MC74HC4067ADWG finds applications in various fields, including:

1. Analog and digital signal multiplexing in communication systems.
2. Data acquisition systems for selecting different input sources.
3. Audio and video routing in multimedia devices.
4. Industrial automation for channel selection in control systems.
5. Test and measurement equipment for signal routing and switching.
