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.

Right now I have a chip debouncing a switch and and output from that going into the count-up terminal of the I’d datasheef not go with the because it counts in binary. Jul 17, 22, 1, They all just stay at low, even though I’m dtasheet the counter input a pulse. I’ve tried many different dataeheet but haven’t had any luck. Russlk New Member Dec 19, For a better experience, please enable JavaScript in your browser before proceeding.


The count-down terminal is held high. Terminal count up pin 12 connects to clock pulse up pin 5 of the next stage. You must log in or register to reply here. We’ll need the schematic you’re useing to help. In order to use the ‘, you will have to decode the 10 count and use it to clock the next stage and reset the first stage. I hope I’ve described my situation well enough, I just can not figure out why the counter isn’t counting. I followed your advice and held pin 11 load pin low and held pin 14 reset high and the counter counted!

Confirm that 5V power is present on the Power pin pin 16 and ground is present on pin 8. Quote of the day. Datasheets, Manuals or Parts. I have read the data-sheets and read quite a bit on this forum as well, but nothing I try seems to work.

Often there is a timing diagram that contains the same information along with the critical timing information as well. My best guess is that the pulse is too slow, but even when I apply a Hz square wave nothing happens.
