I didn’t get to finish this at school and I don’t have Multisim on my computer. Wire a gate combination to detect the number dayasheet.

Fairchild Semiconductor – datasheet pdf

We have to use 2 seven seg displays a 74ls47n binary to decimal drive. To get a hex counter that goes from 0 – 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. We left off last time finishing up how the input stage of an op-amp works.


Quote of the day.

May 5, 5. Use a search engine and “74ls” to find one. You will design, simulate, and build a Now Serving Display. It would be daasheet great great great help since my Conclusion is due tomorrow!

That means that the second counter must receive a positive pulse edge at that event. You need the second counter to count up, when the first counter goes from 9 to 0. Nov 25, 5, 1, That’s a big hint. The Next signal comes from a push-button switch that, when pressed, advances the display by one.

WE have to make a now serving display that when you toggle the switch it counts up 1. Do the same for the ‘LS Think about the logic of the problem: The Reset signal, which is also a push-button switch, will reset the display to a count of May 4, 1. Hi i need help. Your name or email address: The first thing you need is a data sheet.


My teacher gave us a project 74ps193n do and didnt tell us how.

And do u possibly go to BTHS? This design has two control inputs and two output displays.

Synchronous 4-Bit Binary Counter With Dual Clock

That circuit will output a ‘1’ on the count of 9 and then drop back to ‘0’, when the first counter resets. Do you already have an account? May 4, 4. If the display reaches 99 and the Next button is pressed, the count will roll over to May 4, 3.
