That will probably confuse whatever you’re using to display the result and will prevent you properly cascading multiple datashset to produce displays with more than one digit.
Help! with 74LS93N Counter
Oct 12, 5. But they refer to them as “set-to-nine” inputs 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.

Oct 11, 3. When the counter reaches 9 you want the next count to change it to Your circuit is suffering from the dreaded “switch bounce”.
Question regarding 74ls90’s and 74ls93 Ask Question. Help with counter circuit? THere will be circuits onlime that do this OR ask again if more help needed.
Finbarr 3, 1 9 Entrepreneur 2 5. Also, I dont see any decoupling capacitors on the IC. The OP can’t get a 74LS Along with what Marshallf3 said 0.
Yes, it’ll work to a point – specifically, until the count reaches 9. Help with binary counter Posted by solidrock in forum: If you are allowed to have it count to 15 rather than 9 then it will work fine.
Home Questions Tags Users Unanswered. It sounds like switch or contact bouncing. Posted by SevenSeas in forum: Apr 11, 3, 1, Also, it would be interesting to know whether your 7-segment display will properly display digits above 9 or if it will display nonsense.
Yes, I have to agree.

Voltage and Current Dividers: Chris vd Merwe 3 2. Good point, Tut – guess they’re not going to be useful after all. Dahasheet as a guest Name.
You would have to figure out how to asynchronously reset the ’93 so you don’t get counts 0xA and above. After i finished doing all the truth tables and drawing the logic diagram, i decided to simulate it first before getting into any hardware stuff. Discussion in ‘ The Projects Forum ‘ started by idmondOct 11, Email Required, but never shown.
Read up on the problem and various solutions here: The 74LS93 is a binary counter, so it will carry on past 9 and count up to 15 F in hexadecimal or in binary.

In fact, as 74ls93j start churning out more and more connected gadgets, security isn’t a top concern. It depends on if you must have it roll from 9 to back to 0 on the next count. Quote of the day.
Read the data sheets for the devices first then ask a question based on what you don’t understand.
