Working Principles

The CD74HCT153M operates as a dual 4-to-1 multiplexer/demultiplexer. It selects one of the four input signals based on the select inputs (S0 and S1) and routes it to the corresponding output (Y0 to Y3). The enable input (E) controls the overall operation of the IC. When enabled, the selected input is passed to the output; otherwise, all outputs are in a high-impedance state.

Detailed Application Field Plans

The CD74HCT153M finds applications in various digital systems where multiplexing or demultiplexing of signals is required. Some common application areas include:

1. Data communication systems
2. Digital audio/video equipment
3. Industrial automation
4. Automotive electronics
5. Medical devices
