The Learning Circuit 76: How to Make a 4-bit Shift Register Circuit

element14 presents
How to Make a 4-bit Shift Register Circuit

The Learning Circuit | element14 presents |  Project Videos

 

 

After learning about shift registers, Karen shows how to use one in a circuit. Shift registers can take data from a single input and transfer it to multiple outputs or take data from multiple inputs and transfer it to a single output. In this video, Karen shows how to use a 4-bit, bidirectional shift register in a circuit. This shift register has 4 parallel inputs and outputs where data can be transferred. It also has two serial inputs, that can be used to shift data left or right across the 4 outputs. After seeing how the circuit is made, can you think of a way to use this universal shift register in a project? Post your ideas in the comments below or find Karen and tell her about it on the element14 Community!

  • how to made a 16 bit PIPO shift register

  • Hi Karen,

     

    This looks like a fun circuit to play with. Thanks for the nice demonstration.

    Oh, that's a really cool application. Thanks for sharing!

  • Very good explanation.

     

    Uses for the 194 chip were many.

    I have seen them used to take parallel data and then use the serial output to send the data over long distances and then use them to read out the parallel data at a remote site. We did this when internet and ethernet were still in development.

     

    One very important use for this chip is to introduce a chirp signal for things like range finders. You enter the chirp code you want and then transmit the chirp out using the serial sequence for timing. The receiver picks up the returning signal and cycles the bits through until you match the chirp, signifying an accurate signal return. Quick, simple and easy to use, especially in noisy environments.
