Replacing a 4 pin leaded inductor with a 2 pin Started by gkmaia Yesterday at Russlk New Member Dec 16, Hardware, Tools, and Toolchain This is Part 1 of a step-by-step guide to bringing custom microcontroller designs datashete life.

The count-down terminal is held high.

Jan 26, 3. A Tale of 3 Smart Cities: Mar 24, 21, 2, Thread starter lhanx2 Start date Dec 16, 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 pulse?

Jan 28, 9, Satasheet followed your advice and held pin 11 load pin low and held pin 14 reset high and the counter counted!

Terminal count up pin 12 connects to clock pulse up pin 5 of the next stage. Your name or email address: I’m wondering if I’m not sending it a pulse that it can recognize as oc clock cycle, or if there’s just something weird with the chip.

You May Also Like: We’ll need the schematic you’re useing to help. Right now I have a chip debouncing a switch and and output from that going into the count-up terminal of the Jan 26, 2. 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.


questions about 74193 counter

Russlk New Member Dec 19, 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.

Discussion in 47193 The Projects Forum ‘ started by gcentauriJan 25, Welcome to our site! You would then have a problem of converting from binary to bcd for use in the display.

To participate you need to register. My best guess is that the pulse is too slow, but even when I apply a Hz square wave nothing happens. I have read the data-sheets and read quite a bit on this forum as well, but nothing I try seems to work.
