Nov 24, Nov 23, 8, datashet, If you are using TTL which your part number implies, but which I suspect may be somewhat inaccurate you will need to take into account the input currents. What is the debounce device you purchased? What is the IC, and how does it work? I guess this is not THAT big of daatasheet deal to me, but for my device to be more user friendly, i’d like it to clear when you press clear only.

I cannot get this circuit to work correctly on my breadboard at home and dont know why! Jun 18, RCO of the second counter will go high when the output is 99, so this can be used to enable a third counter, which will then count hundreds. You need asynchronous reset, whether it’s a synchronous counter or not is less of an issue. For the theory on switch debouncing, try http: You’ll need to choose a username ci the site, datsaheet only take a couple of moments here.

Consider the clear function — if you do that more than once, is it a problem?

The inputs I have seen sit high and need to be pulled low. I have downloaded datasheet.


Then you need a BCD counter remember it goes from 0 to 9 only. Answered Jul 24, At first it just stayed at 0 and didnt change, then i unconnected the Common cathode mine only has one on my 7 seg and re connected and it counted all the way to 8 but then stopped.

I am looking LTspice model file for 74ls counter. It always pays to read the specs. Sign up or log in Sign up using Google. They are useful in designing state machines where you need to “hold the present state” until a specified condition occurs. My ic is an 8bit ic, im assuming i can just ground the other 4 bits im not using and it will still work fine for my application as long as i can use this ic with my ttl parts.

Sep 16, 5. How does the IC work?

Its summer break and i datashfet dont want to bother my professor I have tried a momentary N. This means that if MR goes low the and will reset immediately even for a brief spike while the and will only respond on the clock edge. We dstasheet so, we haven’t tested the switch with a ‘scope. Promote your business on Quora – it’s where people look for reliable information about your industry.

A 74LS has asynchronous reset.

74ls163 counter need help

A is a decimal counter. Distribution of a Use k for each of the resistors in the Schmitt trigger circuit.

You need to consider a pair of decade counters or BCD counters rather than a binary ix. The difference can be found on the data sheets: Let’s start with kilohms. As you can see, changing from 4 binary digits lc a pair of 7 segment displays can play havoc with your design. Clock inputs on many logic chips like to have clean, fast rise and fall times. Discussion in ‘General Electronics Discussion’ started by dustin02rsx, May 18, How does MT IC work? He owes his success to 1 datxsheet.


I am using my 74ls47 7 seg driver in conjunction with one of the two 7 seg displays on my dual 7 seg. My problem is, every switch i use, i have to press a lot jc even get a reading, then when i get a reading its not always accurate. Someone can tell me where to get LTspice model file for 74ls They may also have a collection of application notes collected in book form, too.

What is the problem that you see?

As you can see in the internal diagram, the counter has only one set of flipflops that are used to hold the count, so there is no way it could remember that you want it to allways start beginning with 6.

Sep 16, 1. Here is my wiring.

So in order to make a counter do something other than simple divide by 10 counting, you can make a counter which will recycle on any count you like. So it enables the counters but does not affect datssheet transition count. Now you can guess at a time constant for the RC network to debounce the switch.

Post as a guest Name.

This allows, among other things, much easier feedback by decoding the counter outputs, since they all change at the same time dataseet you don’t get the “skew delays” which plague ripple counters. I do not know if it is N.
