This circuit is a synchronous up down 4-bit binary counter. Synchronous operation is provided by having all flip-flops clocked simultaneously so that the outputs. 74LS datasheet, 74LS pdf, 74LS data sheet, datasheet, data sheet, pdf, Fairchild Semiconductor, Synchronous 4-Bit Binary Counter with Dual Clock.

Welcome to our site! The count-down terminal is held high. Do you already have datsaheet account? Russlk New Member Dec 19, To participate you need to register.
Confirm that 5V power is present on the Power pin pin 16 and ground is present on pin 8. Do you have LOAD pin 11 held high? You must log in or register to reply here. Any help would be great. Jan 26, 8. I’ve tried many different set-ups but haven’t had any luck.
I’d would not go with the because it counts in binary.
Right now I have a chip ddatasheet a switch and and output from that going into the count-up terminal of the Jan 26, Jan 28, 9, Replacing a 4 pin leaded inductor with a 2 pin Started by gkmaia Yesterday at Yes, my password is: In order to use the ‘, you will have to decode the 10 count and use it to clock the next datasheett and reset the first stage.
They all just stay at low, even though I’m giving the counter input a pulse. If not, it’ll always be loading the data inputs into the data outputs. Forums New posts Search forums. Quote of the day.

My best guess is that the pulse is too slow, but even when I apply a Hz square wave nothing happens. Jan 25, 1.

You would then have a problem of converting from binary to bcd for use in the display. Replacement Transformer Started by ncag Today at 7: This IC is a discontinue item.
No, create an account now. I’m wondering if I’m not sending it a pulse that it can recognize as a clock cycle, or if there’s just something weird with the chip. A Tale of 3 Smart Cities: Jan 26, 9. Jan 26, 6.
Often there is a timing diagram that contains the same information along with the critical timing information as well. So my first project has been to try and make a 7-segment display count up from 0 to 9 using some kind of button press. 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 thing to count.
