down counter using 74193 ic - All About Circuits
2016年10月1日 · Those values concatenated with a constant, always 1, least significant digit, make up the desired sequence. Preset the counter to 4, aka 100, let it count down to 0, and reset the counter to 4 on the next clock after the counter reaches 0. Recognizing patterns is half the secret to clever logic and state machine design.

[HELP] 74ls193 count up and down as BCD | All About Circuits
FarProd. Joined Feb 9, 2012. 10. Feb 11, 2012. #4. My goal is to use 74ls193 as counter and design BCD up and down counter from 00 - 99 vice versa (2 digits). I figured out how 74ls193 work as BCD counter, but the problem is, when it count down, from 9 - 0.. it doesn't come back to 9.. it stay at 0 all the time. F.
problem getting a 74193 counter to count up consecutively, at its …
2024年6月25日 · Hello AAC, I am hoping to get some help getting a 74193 counter IC working properly. After a momentary High is put on the clear pin, the Q-outputs will all go Low properly, but the Q-outputs do not increment in sequence, as they should. The binary count output varies; it will sometimes increment...

2009年1月25日 · The counter chip I had on hand was a 74193, and 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. I've tried many different set-ups but haven't had any luck. I'm wondering if I'm not sending it a pulse that it can recognize as a clock cycle, or if there's just something ...
How to count from 0 to 4 only using a 74193 or 74191?
nivekevin. Joined Oct 5, 2010. 9. Oct 5, 2010. #1. Hi! I am wondering how can I allow the 74193 or 74191 (synchronous 4 bit up/down counter) chips to count from 0 to 4 or 4 to 0 only (i just want it to count for 5 clock cycles... meaning that after that the counting would reset to 0 again... i guess some logic gates are needed to implement it ...

Counting 0-9 and vice versa - All About Circuits
2014年4月17日 · First of all, is this a good summary of your requirements: In counting up, when the counter reaches 9 and then increments from 9 to 10 (A), you want to detect this, reset the counter to zero, and then have it continue to count up, emulating a 7490. In counting down, when the counter reaches 0 and then decrements from 0 to 15 (F), you want to ...
