My best guess 74,s193 that the pulse is too slow, but even when I apply a Hz square wave nothing happens. You May Also Like: Do you have LOAD 74ls193 datasheet 11 held high?

Click here to register now. Jul 17, 74ls193 datasheet, 1, I’m wondering if I’m not sending it a pulse that it 74ls193 datasheet recognize as a clock cycle, or if there’s just something weird with the chip.

Electronics Forum Circuits, Projects and Microcontrollers. The counter chip I had on hand was aand I’ve spend a lot of time reading up on it and trying to make it work, but for the life of me I can’t get the 74ls193 datasheet to count.

This feature allows the counters to be used as modulo-N dividers by simply modifying the count length with the preset inputs.

Discussion in ‘ The Projects Forum ‘ 74ls193 datasheet by gcentauriJan 25, 74ls193 datasheet The counters can then be easily cascaded by 74ls193 datasheet the borrow and carry outputs to the count down and count up inputs respectively of the succeeding counter.

No, create an account now. When I flip the switch I know I’m getting a slow pulse maybe that’s the problem, and 74ls193 datasheet so, is there a circuit I 74lw193 build to make a quick single pulse?

A clear input has been provided which, when taken to a high level, forces all outputs to the low level; independent of the count and load inputs. This was my first experiment with digital logic though, so maybe it will just make more sense as 74ls193 datasheet work with things.

Dec 5, Messages: The borrow output produces a pulse equal in width to the count down input when the counter underflows. Jan 26, 2. 74ls193 datasheet IC is a discontinue item. Your name or email address: I followed your advice and held pin 11 load pin low and held pin 14 reset high and the counter counted! I need to know what 74ls193 datasheet to datssheet together.

I hope I’ve described my situation well enough, I just can not figure out datqsheet the counter isn’t counting. Yes, my password is: You won’t need the inverter in the clock line if your clock doesn’t go anywhere else.

The circuit overflows from 9 back to 0 and continually repeast the count. If datzsheet, it’ll always be loading the data inputs into the data outputs.

I am having difficulty making the 74LS automatically count up and then recycle and count back down. Your name or email address: I had to switch the wires of 74ls193 datasheet clock and the high between pins 4 and 5 to 74ls193 datasheet it count down. I read your post about cascading them together.
