You’ll still need debouncing, maybe your existing debouncer can be used. Need help with counter Posted by ctonton in forum: I used a 0.

The inputs I have seen sit high and need to be pulled low. The 74LS47 datwsheet a common anode display and resistors for the segments. Someone can tell me where to get LTspice model file for 74ls Then you need a BCD counter remember it goes from 0 to 9 only.

How about having the circuit settle in 20ms? It allows the chip to trigger a second chip to count how many times this one rolls over from 15 back to 0 – that way, you can cascade multiple chips and make it an 8, 12 or 16 bit counter or more. 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. What is the debounce device you purchased?


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. How does IC work? StoreCatalogDrillDownView links contain the pdf data sheet the dual 7 seg display data sheet sucks and i know the 4 bit decoder is CMOS but the majority of my parts are ttl.

Iic to create a datssheet clock signal.

SN74163N Texas Instruments Synchronous 4-Bit Counter

I believe the “pulser” switch is a momentary toggle switch. For the theory on switch debouncing, try http: Similar Threads Microchip reading and copying data. Building a simple clock. I am now loading 0 at 7416 on my 74ls so it is basically like i have a BCD counter. I suggest you check with them and ask for a datasheet and any application notes they might have for it.


Nov 24, And then your problem is that if you want 0 to 12, that requires 2 digits and a decoder to do that is not gong to be trivial. How does ICS work? This counter do two things, increments or load the new value. What People Are Talking About: Answered Jul 24, Sep 16, 8. You dismissed this ad.

I am now getting a clean count with my debounce IC. Beside documents, they often have application engineers who can help you if you have a specific question, and you represent a company that might be placing a large order for one of their products.


A is a 4 line to 16 line decoder and it’s not going to make driving the LED display easy you could do it, but you’d require a dozen transistors and possibly 50 diodes.

You need to debounce your switches. Feb 24, 11, 2, Jun 13, I don’t have my datsheet handy it is packed away in preparation for a movebut ENT and ENT pins are used to enable counting. May 19, 7. The Oc chip is synchronous – when the clear pin is LOW when a clock pulse goes low to high, the outputs datawheet – if the enable P ENP pin is High, the output will increment with each clock tick if clear is not low.

How does an IC regulator work? It works fine in binary and i dont have any problems until i try the 7 seg display. Jun 14, Nov 23, 8, 6, You must log in or sign up to reply here.

The datasheet on the display seems perfectly fine to me. How does a Counter IC works? Jun 16, You need to consider a pair of decade counters or BCD counters rather than a datashet counter. If you’re dealing with CMOS, you can generally use high value resistors with gay abandon. May 18, 4.
