But when I hooked them up to the inputs one to the Up and one to the Downthe display when all haywire, as though the button was just held low, and it just kept cycling through digits.

Perhaps more to the need is something like a logic simulator – http: I purchased a few counters and a few BCD decoders. That only leaves the as the culprit so basically, I probably have it wired incorrectly. I’ve tried both arrangements, but to no avail. Previous 1 2 If it’s a BJT timer, the output may not be going high enough to be detected as a logic “1”. Jun 30, 6. This was the first edition of th.


The pulse generators have the following characteristics: Jul 1, This mode of operation eliminates the output counting spikes which are normally associated with asynchronous ripple- clock counters.

From Wikimedia Commons, the free media datxsheet. IC decoder pin diagram Abstract: When counting up, count-down Input must be high; when counting down, count-up input must be high. This file contains additional information such as Exif metadata which may have been added by the digital camera, scanner, or fatasheet program used to create or digitize it.

Load preset to binary thirteen. The counters can then be easily cascaded by feeding the borrow and carry outputs to the count-down and count-up inputs respectively of the succeeding counter.

Apr 20, 15, The Up works, the Fatasheet works; the problem is in the switching back and fourth. Count down to one, zero, borrow, nine, eight, and seven.
