# What is a 1/4 demultiplexer?

## What is a 1/4 demultiplexer?

A 1-to-4 demultiplexer has a single input (D), two selection lines (S1 and S0) and four outputs (Y0 to Y3). The input data goes to any one of the four outputs at a given time for a particular combination of select lines.

How many and gates are required for 1 to 4 demultiplexer?

Therefore, for 1:4 demultiplexer, 2 select lines are required. Explanation: A demultiplexer sends a single input to multiple outputs, depending on the select lines.

### What is demultiplexer explain with diagram?

De-Multiplexer is a combinational circuit that performs the reverse operation of Multiplexer. It has single input, ‘n’ selection lines and maximum of 2n outputs. The input will be connected to one of these outputs based on the values of selection lines.

Which logic gates are used in demultiplexer?

IC 74LS154 can be used as a decoder-demultiplexer IC as it performs both operations. 1.2 Design a 1:2 demux using basic universal logic gates. NAND & NOR gates are called as universal logic gates.

## What is a multiplexer explain 4 1 multiplexer in brief?

A 4-to-1 multiplexer consists four data input lines as D0 to D3, two select lines as S0 and S1 and a single output line Y. The select lines S0 and S1 select one of the four input lines to connect the output line.

How many OR gates are required for a 1 to 8 demultiplexer?

8 AND gates
For a 1 to 8 multiplexer a total of 8 AND gates are required.

### What is demultiplexer in digital logic design?

The demultiplexer is a combinational logic circuit designed to switch one common input line to one of several seperate output line. The data distributor, known more commonly as a Demultiplexer or “Demux” for short, is the exact opposite of the Multiplexer we saw in the previous tutorial.

What is microprocessor demultiplexer?

Demultiplexing (Demuxing) is a term relative to multiplexing. It is the reverse of the multiplexing process. Demultiplex is a process reconverting a signal containing multiple analog or digital signal streams back into the original separate and unrelated signals.

## What is a 4 to 16 decoder?

A 4-to-16 decoder consists of 4 inputs and 16 outputs. Similar to all the decoders discussed above, in this also only one output will be low at a given time and all other outputs are high (using maxterms).

What is the input for an 8 to 1 multiplexer circuit?

An 8-to-1 multiplexer consists of eight data inputs D0 through D7, three input select lines S0 through S2 and a single output line Y. Depending on the select lines combinations, multiplexer selects the inputs.

### How many selection lines are required to design a 1/16 demultiplexer?

We can implement the 1×16 de-multiplexer using a lower order de-multiplexer. To implement the 1×16 de-multiplexer, we need two 1×8 de-multiplexer and one 1×2 de-multiplexer. The 1×8 multiplexer has 3 selection lines, 1 input, and 8 outputs.

How many 1 line to 8 line demultiplexers are required for a 1 of 32 demultiplexer?

(32÷8) + (4÷8) =4.5. So, the answer is 4. What is a demultiplexer? 5 input lines is the correct answer.

## What are the types of demultiplexer?

The different types of demultiplexers are 1-8 Demux, 1-16 Demux, 1-32 Demux. In demultiplexer, the selection of output line can be controlled through n-selection lines bit values.

How do you implement a 4 1 multiplexer?

From the above expression of the output, a 4-to-1 multiplexer can be implemented by using basic logic gates. The below figure shows the logic circuit of 4:1 MUX which is implemented by four 3-inputs AND gates, two 1-input NOT gates, and one 4-inputs OR gate.

### What is multiplexer with logic circuit and function table explain the working of 4-to-1 line multiplexer?

A 4-to-1 multiplexer is a digital multiplexer that has four data inputs, two select lines, and one output. To implement a 4-to-1 multiplexer circuit we need 4 AND gates, an OR gate, and a 2 NOT gate. data control lines.

What is a 4 input decoder?

A BCD number needs 4 binary digits to represent the 0 to 9 decimal digits, thus it consists of 4 input lines. It consists of 10 output lines corresponding to 0 to 9 decimal digits. T. This type of decoder is also called as a 1 to 10 decoder.

## How many outputs does 1×4 de-multiplexer have?

1×4 De-Multiplexer 1×4 De-Multiplexer has one input I, two selection lines, s 1 & s 0 and four outputs Y 3, Y 2, Y 1 &Y 0. The block diagram of 1×4 De-Multiplexer is shown in the following figure. The single input ‘I’ will be connected to one of the four outputs, Y 3 to Y 0 based on the values of selection lines s 1 & s0.

What is a demultiplexer circuit?

Demultiplexer or Demux is a combinational circuit that distributes the single input data to a specific output line. The control inputs or selection lines are used to select a specific output line from the possible output lines. Demultiplexer works opposite to that of the multiplexer.

### What are the common selection lines applied to 1×8 de-multiplexer?

The common selection lines s2, s1 & s0 are applied to both 1×8 De-Multiplexers. The outputs of upper 1×8 De-Multiplexer are Y 15 to Y 8 and the outputs of lower 1×8 DeMultiplexer are Y 7 to Y 0.

What is a 1-to-8 demultiplexer?

Similar to the 1 to 4 demux, 1-to-8 demultiplexer performs the transfer of single data to any one of the 8 possible outputs. It has 3 selection lines to distribute the data to the output. The operation is similar to a 1-to-4 demux.
