But the other way that comes to mind is resetting the chip when the count reaches 6, eg: Still haven’t had any success on electronics workbench – something funny there!

I’m trying to understand how I can set my own sequence of numbers with a 74ls90 decade counter and 74ls47 BCD to seven segment decoder. Russlk New Member Mar 20, Salam, Argo Satrio Wicaksono Balas.

If you are interested the project is at: Samcheetah, the logic inputs always need H or L level. Posted by fahmizaleeits on Desember 20, at 8: PLease I wanna make the 74ls90 work as a Decade 6 Counter if you got any idea about this please inform me.

I’ve manged to understand to understand to figure out datashete to reset a count if the numbers are consecutive 0. Welcome to our site! Hi Digimaniac, I have a feeling, reading through the 47ls90 pdf file that you can use the ic 47ls92 as a decade counter, and it may be easier to use that.

Use a simply debouncing cct. MattAyers New Member Mar 21, You must log in or register to reply here.

Counter using 74LS90 and 74LS47

The Same Design but different purpose Hey Guys, I made the same design of this circuit but for the purpose to use it as a digital clock so the first part of the seconds consists of the your design exactlyfirst the pins of the 74ls473, 4 and 5 can left open or joined to the VCC it doesn’t make sense and I experimented both ideas, but I had another Idea if you can help me it will make me more thankful.

A nF ceramic is sufficient across every second IC. The circuit that you have been trying to build worked fine on the old electronics workbench but doesn’t seem to work on the new one! Tinggalkan Balasan Batalkan balasan Ketikkan komentar di sini Bagaimanakan konfigurasinya pin atau kakinya?

Posted by yuriz on Juli 5, at 5: The IC only drives common cathode seven segment displays and the nice part here is that only one IC per display necessary.

I’ve tried that, I’ve just modelled this circuit: I believe his IC is catasheet but I could be wrong.

Apakah anda memiliki rekomendasi rangakaian driver yang lebih sederhana? Mohon penjelasan dan bantuannya mas Fahmi. The relative positive-logic output levels, as well as conditions required at the auxiliary inputs, are shown in the truth tables. Mr Replay New Member Nov 28, Your 74ls90 is OK, but on the 74ls47, pins 3, 4, 5 should be tied high.
