Bus Interfacing: Suitable for interfacing with multiple data lines in applications like multiplexing and demultiplexing.

How to Use:

Connecting the MUX:
- Connect the power supply pins (Vcc and GND) as per your circuit requirements.
- Connect the input lines (I0 to I7) to the signals you want to multiplex.
- Connect the select lines (A, B, C) to your control logic to choose which input to output.
Controlling the Selection:
- Set the select lines to binary values (000 to 111) to choose the corresponding input (I0 to I7).
- For example, if A=0, B=0, and C=1, the output will follow input I1.
Testing the Output:
- Use a multimeter or an oscilloscope to verify that the output changes according to the selected input.
- Ensure the correct logic levels are present at the inputs and observe the output for the expected results.
Integrating into Larger Circuits:
- The 74151 can be used in conjunction with other logic gates, flip-flops, or microcontrollers to create more complex digital systems.
