I want to design using by cascading 74*163 ic

[Atakan]

I want to design such as count at 33 start and run 77 reset.
Is it true my image?

I think you want this.

I think you want this.

how can i interconnect a b c d and Qa Qb Qc Qd, such as where 33? and where 77?

 

[Atakan]

I want to design such as 33,34,35,36,37,38......74,75,76,77 and finishing.
secondly 33,34,35,36,37,38...74,75,76,77,33,34,35,36,37......
how can i do this? have you any examples about this tasks? i could not do it

is it true?

I'm sorry,. I can't understand what you want.

i want to design counter 33 to 77. but i want just using 74*163. because i am not sure what i do.

What is 33 to 77? Please tell us more about your project.
Thanks

I have an exam. A question will be cascading counters and digital 74x163. Such as this is starting at count 33 and finishing 77 otherwise starting at count 0 and finishing 80
Etc. I could not do this question i could not draw with my hand. I am just doing 0- 15 at counting circuit

First you need to understand how to cascade the devices so you can count to a higher number than 15.

Then you need to understand how to load a number into them.

Then you need to work out the logic to decide if you have reached a certain maximum count.

You might want to look for an 8 bit magnitude comparator as that will make the last part easier.

Pins 1, 2 and 9 have no input. Yes, they need to be connected together, but they need an input from something. The Preset inputs need to be either high or low, not floating.



If this example is good for you, I have most TTL and CMOS chips done up this way. I used to teach this stuff.
