Working Principles

The MM74C154N is a decoder/demultiplexer IC that converts a 4-line binary input into a 16-line output. It utilizes TTL logic to perform the decoding operation. The address inputs (A0-A3) determine which output line is selected, while the enable inputs (E1 and E2) control the overall operation.

When the enable inputs are active (low), the decoder/demultiplexer is enabled, and the selected output line reflects the binary value applied to the address inputs. The remaining output lines remain in a high impedance state.

Detailed Application Field Plans

The MM74C154N can be used in various applications, including:

  1. Address decoding in microcontrollers and microprocessors
  2. Data routing and selection in digital systems
  3. Memory addressing in RAM and ROM modules
  4. Signal routing in communication systems
  5. Multiplexing and demultiplexing operations in data transmission
