Working Principles

CD4555BM utilizes CMOS technology to perform the multiplexing and demultiplexing functions. The channel select inputs (A0-A7) determine which input channel is selected, and the corresponding data is routed to the output pin (Y). The enable inputs (E1-E4) control the operation of the IC, enabling or disabling the multiplexing/demultiplexing functionality.

Application Field Plans

CD4555BM finds applications in various digital systems where multiple signals need to be transmitted over a single line. Some potential application fields include:

1. Data communication systems
2. Telecommunication equipment
3. Industrial automation
4. Audio/video signal routing
5. Instrumentation and measurement devices
