Working Principles

The MC14538BDWR2G is a digital multiplexer/demultiplexer IC that operates based on the principle of data selection. It has three select inputs (A, B, and C) that control the routing of the data input to one of the eight output channels. The enable input (pin 3) activates the IC when set to a logic high level.

When used as a multiplexer, the MC14538BDWR2G selects one of the eight data inputs based on the combination of select inputs. The selected data is then routed to the corresponding output channel. As a demultiplexer, it performs the reverse operation by taking a single data input and directing it to one of the eight output channels based on the select inputs.

Detailed Application Field Plans

The MC14538BDWR2G finds applications in various fields, including:

1. Data communication systems
2. Digital audio/video equipment
3. Industrial automation
4. Automotive electronics
5. Medical devices
6. Consumer electronics
7. Robotics
8. Security systems
