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.

If not, it’ll always be loading the data inputs into the data outputs. Jan 26, 9. Yes, my password is: Jan 25, 3 0.

Replacement Transformer Started by ncag Today at 7: The count-down terminal is held high. You May Also Datasheett Do you have LOAD pin 11 held high? Do you already have an account?
My best guess is that the pulse is too slow, but even when I apply a Hz square wave nothing happens. When I flip the switch I know I’m getting a slow pulse maybe that’s the problem, and if so, is there a circuit I can build to make a quick single xatasheet To participate you need to register. Media New media New comments Search media. Often there is a timing diagram that contains the same information along with the critical timing information as well.
Jan 26, Russlk New Member Dec 19, I followed your advice and held pin 11 load pin low 47193 held pin 14 reset high and the counter counted!

This was my first experiment with digital logic though, so maybe datwsheet will just make more sense as I work with things. I have read the data-sheets and read quite a bit on this forum as well, but nothing I try seems to work. I’ve tried many different set-ups but haven’t had any luck.
No, create an account now. Terminal count up pin 12 connects to clock pulse up pin 5 of the next stage.
Datasheets, Manuals or Parts. Right now I have a chip debouncing a switch and and output from that going into the datahseet terminal of the I hope I’ve described my situation well enough, I just can not figure out why the counter isn’t counting.
You would then have a problem of converting from binary to bcd for use datasyeet the display. Apr 14, 7, Hardware, Tools, and Toolchain This is Part 1 of a step-by-step guide to bringing custom microcontroller designs to life.

Electro Tech is an online community with overmembers who enjoy talking about and building electronic circuits, projects and gadgets. Russlk New Member Dec 16, Confirm that 5V power is present on the Power pin pin 16 and ground is present on pin 8. I’d would not go with the because it counts in binary.
