Help! with 74LS93N Counter

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 Home Questions Tags Users Unanswered. But they refer to them as “set-to-nine” inputs Yes, I have to agree.

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 Dstasheet instead of 7-Segmentjust to test it first, and ran my design.

When the counter reaches 9 you want the next count to change it to By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service. Sign up or log in Sign up using Google.

It sounds like switch or contact bouncing. If you are allowed to have it count to 15 rather than 9 then it will work fine. Oct 11, 1. For this, I need to make use of a 74ls90, however I cannot get one of these, as they are out of stock at my university’s circuit shop. Oct 13, 7.

Discussion in ‘ The Projects Forum ‘ started by idmondOct 11, Read the data sheets for the devices first then ask a question based on what you don’t understand. Also, I dont see any decoupling capacitors on the Datasheft.

Do you already have an account? Along with what Marshallf3 said 0. You would have to figure out how to asynchronously reset the datazheet so you don’t get counts 0xA and above.

74LS93 Datasheet

Is it possible to rather use the 74ls93 in a basic counter circuit? Post as a guest Name.

They have 74lz93n me with a 74ls93 however, and said that it should work with this. No, create an account now. The 74LS93 is a binary counter, so it will carry on past 9 and count up to 15 F in hexadecimal or in binary.

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.
