How many OR gates are required for the construction of a 32 to 1 multiplexer?
To implementing the 32-to-1 MUX, five selection lines are needed. Here A, B, C, D and E are the selection line inputs. In which the most significant ‘A’ select line is connected to 2-to-1 MUX.
What is a 74151 multiplexer?
The TTL/MSI SN54/74LS151 is a high speed 8-input Digital Multiplexer. It provides, in one package, the ability to select one bit of data from up to eight sources. The LS151 can be used as a universal function generator to generate any logic function of four variables.
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 can build a 32 1 mux using multiple 4 1 mux and few logic gates?
Use 4 8:1 MUXs to get the 32 bits down to 4, then use half of one 8:1 MUX to get those 4 bits down to one. Each MUX requires 3 bits to select. So you connect all of the selection bits for the four input MUXs together, this means that one input from each MUX will be applied to the output MUX.

What is the function of the strobe pin in 74151 IC?
A Strobe input is provided which, when at high level, disables all data inputs and forces Y output to low state and W output to high state.
The DM74150 selects one-of-sixteen data sources. The DM74150 has a strobe input which must be at a LOW logic level to enable these devices. A HIGH level at the strobe forces the W out- put HIGH and the Y output (as applicable) LOW. The DM74150 features an inverted (W) output only.
What is multiplexer IC?
A Multiplexer IC allows you to interface a number of pins, with a single pin, by using a set of state pins to determine which ones are connected. e.g. you could have 8 LEDs as Outputs, all controlled from a single output. You could also have 8 different switches as Inputs, which are all interfaced to a single input.
