Functional Features

  • CD4055BMT acts as an 8-channel multiplexer/demultiplexer.
  • It can select one of the eight input channels and route it to the output line based on the address inputs.
  • The enable input (E) controls the operation of the IC.
  • The IC has a built-in latch that holds the selected channel until a new selection is made.

Advantages and Disadvantages

Advantages

  • Wide operating voltage range allows compatibility with various systems.
  • Low power consumption makes it suitable for battery-powered devices.
  • High noise immunity ensures reliable operation in noisy environments.
  • Compact SOIC package enables space-efficient PCB design.

Disadvantages

  • Relatively high propagation delay may limit its use in certain high-speed applications.
  • Limited number of input channels compared to other multiplexer/demultiplexer ICs.

Working Principles

The CD4055BMT operates based on the principle of digital multiplexing and demultiplexing. When the enable input (E) is high, the address inputs (A0-A3) determine which input channel (B0-B7) is connected to the output (Y). The selected channel remains connected until a new selection is made.
