I’m doing a counter circuit with three digits, so I have a counter for datashfet digit, however, it starts from zero and sometimes random numbers.

74HC192 – Decade Up/Down Counter with Clear

Jun 7, 5. Welcome to our site! Replacing a 4 pin leaded inductor with a 2 pin Started by gkmaia Yesterday at Click here to register now.

I think xatasheet are reffering to U8: You will have to use logic gate so combine the two outputs. By continuing to use this site, you are consenting to our use of cookies.

Are you sure that the push PL switch is drawn correctly.? How can I get the counter to start from 9?

Yes, my password is: I have succesfuly connected the circuit having 2 74HC, and 2 seven seg displays. So when the switch is operated the contacts open, this would make sense. Jun 7, 6. That will reload the counters. Thanks for letting us know about the procedure for loadining 74hc with the number. Your name or email address: Posted by shengwuei in forum: Jun 7, 8.


Yes yes, the switch is not pressed before the user adjusts the dipswitch for the number he wants. Jun 8, 2 0. Dear all, I am trying to make a BCD counter decrementing from any number, max 99 decremetning to 00 and then starting back again.

Jun 8, Yes I know that it is floating, since I tried several different ways. The new board can balance up to six supercapacitors of any size. Jun 7, 4. The Bartlett Versus the Catasheet Window In this article, we will discuss the fact that choice of different window functions involves a trade-off between the main lobe width and the peak sidelobe PSL.


Are you using the normally closed contacts on the PL switch.? What are you using the 74HC for in the big picture? I connected the circuit as you told me and is now working good when I press the ‘button’ switch. To gain more insight, we will calculate the Fourier transform of a datasheer window using the Fourier transform of a rectangular window.
