How many multiplexers would be required for building an 8 to 1 line multiplexer?

We know that 4×1 Multiplexer has 4 data inputs, 2 selection lines and one output. Whereas, 8×1 Multiplexer has 8 data inputs, 3 selection lines and one output. So, we require two 4×1 Multiplexers in first stage in order to get the 8 data inputs.

How many 4×1 multiplexers are needed for 16×1 multiplexer?

In a 4:1 mux, you have 4 input pins, two select lines and one output. So, at the least you have to use 4 4:1 MUX, to obtain 16 input lines.

How many select lines does an 8 1 multiplexer have briefly explain the working of a 4 1 multiplexer also draw the logic diagram of a 4 1 multiplexer?

Since there are ‘n’ selection lines, there will be 2n possible combinations of zeros and ones. So, each combination will select only one data input. Multiplexer is also called as Mux. 4×1 Multiplexer has four data inputs I3, I2, I1 & I0, two selection lines s1 & s0 and one output Y.

How many selected lines would be required for an 8 line to 1 line multiplexer?

How many select lines would be required for an 8-line-to-1-line multiplexer? Explanation: 2n input lines, n control lines and 1 output line available for MUX. Here, 8 input lines mean 23 inputs. So, 3 control lines are possible.

How many data select lines are required for selecting 8 inputs from 8 1 MUX?

Only three lines are required.

How many select lines does an 8 1 multiplexer have?

3
An 8 × 1 multiplexer selects one of the 8 inputs and presents it to the output, i.e. So the number of select lines will be 3.

How many data select lines are required for an 8 line to 1 line multiplexer?

How many select lines would be required for an 8- line-to-1-line multiplexer? Explanation: 2n input lines, n control lines and 1 output line available for mux. here, 8 input lines mean 23 inputs. so, 3 control lines are possible.
