Functional Features

• CD4508BM is a multiplexer/demultiplexer IC that allows the selection of one input from multiple inputs and routing it to a single output.
• It can also perform the reverse operation, i.e., selecting one output and routing it to multiple outputs.
• The enable input (E) controls the operation of the IC. When E is high, the IC is enabled, and the selected input/output is active.
• CD4508BM operates at high speed and consumes low power, making it suitable for various digital applications.

Advantages and Disadvantages

Advantages

• Versatile functionality as both a multiplexer and demultiplexer.
• Wide operating voltage range allows compatibility with different systems.
• Low power consumption makes it energy-efficient.
• High-speed operation enables quick data processing.
• Compact 16-pin DIP package facilitates easy integration into circuit designs.

Disadvantages

• Limited number of channels (8) may not be sufficient for complex applications requiring more inputs/outputs.
• Propagation delay may affect real-time applications with strict timing requirements.
• CMOS logic family may have lower noise immunity compared to other families like TTL.

Working Principles

CD4508BM utilizes a combination of logic gates and control signals to perform multiplexing and demultiplexing operations. The address inputs (A0-A3) determine the selected input/output, while the enable input (E) controls the activation of the selected channel. The internal circuitry routes the selected input to the corresponding output or vice versa based on the control signals.
