Working Principles

The DG187AP/883 is a digital multiplexer that selects one of the eight data inputs (B0-B7) based on the three address inputs (A0-A2). The selection is controlled by the enable input (E). When E is low, the output Y follows the selected data input. When E is high, the output Y remains in a high-impedance state.

Detailed Application Field Plans

The DG187AP/883 can be used in various applications, including but not limited to:

1. Data routing and switching in digital communication systems
2. Address decoding in microprocessor-based systems
3. Signal selection in test and measurement equipment
4. Multiplexing control signals in industrial automation systems
5. Audio and video signal routing in multimedia devices
