How do you make an 8 1 multiplexer?
How do you make an 8 1 multiplexer?
To implement the 8×1 multiplexer, we need two 8×1 multiplexers and one 2×1 multiplexer. The 8×1 multiplexer has 3 selection lines, 4 inputs, and 1 output. The 2×1 multiplexer has only 1 selection line. For getting 16 data inputs, we need two 8 ×1 multiplexers.
What is a 8×1 multiplexer?
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 and gates are required for a 8 to 1 multiplexer?
For a 1 to 8 multiplexer a total of 8 AND gates are required.
How many select lines are there in a 8 to 1 multiplexer?
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.
What is a 3 to 8 decoder?
A 3 to 8 decoder has three inputs (A,B,C) and eight outputs (DO to D7). Based on the 3 inputs one of the eight outputs is selected. From the truth table, it is seen that only one of eight outputs (DO to D7) is selected based on three select inputs. …
How do you create a multiplexer?
2-input Multiplexer Design
- Q = A.I0.I1 + A.I0.I1 + A.I0.I1 + A.I0.I1
- Q = A.I1 + A.I0
- The Boolean expression for this 4-to-1 Multiplexer above with inputs A to D and data select lines a, b is given as:
- Q = abA + abB + abC + abD.
How do you use 74151 multiplexer?
MULTIPLEXER CIRCUIT USING IC 74151….
- Make the connections as per the logic diagram.
- Switch ON the power supply.
- Apply the combinations of input one by one according it the truth table.
- Note its Corresponding output reading.
- Switch OFF the power Supply.
- Disconnect the components.
How many 2×1 multiplexers are required to construct a 8×1 multiplexer?
Therefore, the overall combination of two 4×1 Multiplexers and one 2×1 Multiplexer performs as one 8×1 Multiplexer.
What is SR latch?
An SR latch made from two NAND gates. An SR latch (Set/Reset) is an asynchronous device: it works independently of control signals and relies only on the state of the S and R inputs. SR latches can also be made from NAND gates, but the inputs are swapped and negated. In this case, it is sometimes called an SR latch.
How many outputs does a multiplexer with 8 data inputs have?
one output
8 to 1 Multiplexer Circuit Diagram An 8-to-1 multiplexer is a digital multiplexer that has 8 data inputs, 3 select lines, and one output. To implement an 8-to-1 multiplexer circuit we need 8 AND gates, an OR gate, and a 3 NOT gate.
How many data select lines are required for selecting 8 inputs in 8 1 mux?
Only three lines are required.
What is 74LS138 decoder?
The IC 74LS138 is a 3 to 8 line decoder integrated circuit from the 74xx family of transistor-transistor-logic-gates. The main function of this IC is to decode otherwise demultiplex the applications. The setup of this IC is accessible with 3-inputs to 8-output setup.
How does a single 8-channel multiplexer work?
For example, a single 8-channel multiplexer. Generally, the selection of each input line in a multiplexer is controlled by an additional set of inputs called control lines and according to the binary condition of these control inputs, either “HIGH” or “LOW” the appropriate data input is connected directly to the output.
What is a digital multiplexer circuit?
Digital Circuits – Multiplexers. Multiplexer is a combinational circuit that has maximum of 2 n data inputs, ‘n’ selection lines and single output line. One of these data inputs will be connected to the output based on the values of selection lines.
What are the data inputs and outputs of 8×1 multiplexer?
The data inputs of upper 8×1 Multiplexer are I 15 to I 8 and the data inputs of lower 8×1 Multiplexer are I 7 to I 0. Therefore, each 8×1 Multiplexer produces an output based on the values of selection lines, s 2, s 1 & s 0.
What are control lines in a multiplexer?
Generally, the selection of each input line in a multiplexer is controlled by an additional set of inputs called control lines and according to the binary condition of these control inputs, either “HIGH” or “LOW” the appropriate data input is connected directly to the output.
