Working Principles

The DM74ALS153MX operates based on the principle of digital multiplexing. It uses control signals to select one out of four data inputs and routes it to the output. The enable input (E) determines whether the multiplexer is active or in a high-impedance state.

When the enable input is high, the selected data input is passed through to the output. When the enable input is low, the output is in a high-impedance state, effectively disconnecting it from the inputs.

Detailed Application Field Plans

The DM74ALS153MX finds applications in various digital systems where data selection is required. Some potential application fields include:

  1. Data routing in communication systems
  2. Address decoding in microprocessors
  3. Input selection in audio/video equipment
  4. Multiplexing control signals in industrial automation
