IC 74193 DATASHEET PDF
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. SN54/74LS is an UP/DOWN MODULO Binary Counter. Separate. Count Up and Count Down Clocks are used and in either counting mode the.

Click here to register now. To daatasheet you need to register. Jan 25, 3 0. 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 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!

Electro Tech is an online community with overmembers who enjoy talking about and building electronic circuits, projects and gadgets. Jan 26, 5. 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.
