SUMMARY

The discussion centers on the need for a chip that can AND a binary string with a control bit, specifically within the 4000 series or 74XX series. A participant suggests using the 7408 quad 2-input AND gate, proposing to wire multiple input pins together to achieve the desired functionality. This approach allows for the creation of a new binary string based on the control bit without the need for constructing a custom circuit.

PREREQUISITES
  • Understanding of digital logic gates, specifically AND gates.
  • Familiarity with the 7408 quad 2-input AND gate.
  • Basic knowledge of binary strings and bit manipulation.
  • Experience with wiring and soldering electronic components.
NEXT STEPS
  • Research the specifications and applications of the 7408 quad 2-input AND gate.
  • Learn about wiring techniques for integrating multiple inputs in digital circuits.
  • Explore alternative chips in the 4000 series that may offer similar functionality.
  • Investigate digital logic design principles to enhance understanding of circuit construction.
USEFUL FOR

Electronics hobbyists, digital circuit designers, and students studying digital logic who are looking for efficient solutions to binary string manipulation using integrated circuits.

Is there a chip (be it 4000 series or 74XX series) that performs the following function? It basically takes in a binary string, and ANDs each part of the string with a certain control bit to produce a new binary string.

It seems that neither muxes nor demuxes serves my purpose. So I'd appreciate if anyone could suggest a chip that does this so I don't have to construct it.

Is the string always going to be 4 bits?

If so you could use a 7408 and wire together 1 set of the input pins and then connect that to the control bit?

ie. from that diagram you could wire together pins 1, 4, 12 and 9 to be your control bit? or a different rearrangement if it was easier to solder together.
