Hi i need help. My teacher gave us a project to do and didnt tell us how. WE have to make a now serving display that when you toggle the switch it counts up 1. We have to use 2 seven seg displays a 74ls47n binary to decimal drive. I know i need to cascade the 74ls to make a eight bit counter but i dont know how. Any help would be greatly appreciated.

And im using multisim You will design, simulate, and build a Now Serving Display. This is the type of display that you would commonly see at a deli counter. This design has two control inputs and two output displays. The two inputs are Next and Reset.

The Next signal comes from a push-button switch that, when pressed, advances the display by one. The Reset signal, which is also a push-button switch, will reset the display to a count of If the display reaches 99 and the Next button is pressed, the count will roll over to May 4, 2. May 4, 3. Apr 20, 15, The first thing you need is a data sheet. Use a search engine and “74ls” to find one.

Do the same for the ‘LS To get a hex counter that goes from 774ls193n – 15 to count 0 – 9, you have to use external logic to set the counter back to 0 instead of going up to 10 Ah. That’s a big hint.

May 4, 4. I did they said that the BO and CO are used to cascade but my teacher said we dont need those. Also i di make a that work i just need to figure out how to make a 8 bit counter using the 74ls May 5, 5. Nov 25, 5, 1, Think about the logic of the problem: You need the second counter to count up, when the first counter goes from 9 to 0.

That means that the second counter must receive a positive pulse edge at that event. You can detect that event with logic gates.

Fairchild Semiconductor

Wire a gate combination to detect the number 9. That circuit will output a ‘1’ on the count of 9 and then drop back to ‘0’, when the first counter resets. Can you imagine what you have to do next, since your counter is positively triggered? May 5, 6. May 8, 7.

It would be a great great great help since my Conclusion is due tomorrow! And do u possibly go to BTHS? You May Also 744ls193n Part 2 How an op amp works with LTspice simulation. We left off last time finishing up how the input stage of an op-amp works.
