  • Which statement best describes the given figure, and what is the function of the terminal labeled EN?

    Which statement best describes the given figure, and what is the function of the terminal labeled EN


  • Options
  • A. Quad two-input multiplexer. EN is the enable input, which requires an active LOW for the device to work.
  • B. Quad two-bit multiplier, EN is the active HIGH trigger.
  • C. Dual quad-input multiplexer, which requires an active LOW on the EN terminal for the device to work.
  • D. Quad two-input AND gate, which requires an active LOW on the EN input to enable all the gates.

  • Correct Answer
  • Quad two-input multiplexer. EN is the enable input, which requires an active LOW for the device to work.
