Is it possible to rather use the 74ls93 in a basic counter circuit? The question is about substituting with a 74LS93 and those only have Reset pins there are no set-to-nine pins on that device. Also, I dont see any decoupling capacitors on the IC.

Dec 5, 5, They have supplied me with a 74ls93 however, and said that it should work with this. THere will be circuits onlime that do this OR ask again if more help needed.

Now, after i found every thing i need, i used Multisim and started connecting the outputs of 74ls93n to drive 4 LEDs instead of 7-Segmentjust to test it first, and ran my design.

Posted by SevenSeas in forum: Oct 11, 4. You would have to figure out how to asynchronously reset the ’93 so you don’t get counts 0xA and above. Actually they are Reset inputs and they could be quite useful see Spehro’s comment.

Yes, it’ll work to a point – specifically, until the count reaches 9. Oct 5, 18 1. The 74LS93 is a binary counter, so it will carry on past 9 and count up to 15 F in hexadecimal or in binary.

Post as a guest Name. I’m trying to build a circuit that counts the number of pulses and displays it on a seven segment display. If you are allowed to have it count to 15 rather than 9 then it will work fine. The OP can’t get a 74LS If you AND the two 1’s you will get an output when the 10 count occurs – this can be used to reset the counter to Question regarding 74ls90’s and 74ls93 Ask Question.

It sounds like switch or contact bouncing. But they refer to them as “set-to-nine” inputs Oct 11, 3. Jul 26, 2, Mar 24, 21, 2, No, create an account now.

Help with binary counter Posted by solidrock in forum: There are also two “Set-to-nine” inputs on the 74LS90 used to set its value directly 74lz93n 9, these should have datssheet tied low if you didn’t need them but should be left unconnected on the 74LS Good point, Tut – guess they’re not going to be useful after all.
