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.

They all just stay at low, even though I’m giving the counter input a pulse. Your name or email address: The count-down terminal is held high. If not, it’ll always be loading the data inputs into the data outputs. I followed your advice and held pin 11 load pin low and held pin 14 reset high and the counter counted!

Jan 28, 9, Russlk New Member Dec datashete, Jan 26, Jan 26, 2. Jan 26, 7. I’m wondering if I’m not sending it a pulse that it can recognize as a i cycle, or if there’s just something weird with the chip. 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.

I’d would not go with the because it counts in binary. 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. Jan 25, 1.
Jan 26, 8. When I flip the switch I know I’m getting a slow dataseet maybe that’s the problem, and if so, is there a circuit I can build to make a quick single pulse?
