74LS93N Datasheet

For this, I need to make use of a 74ls90, however I cannot get one of datashheet, as they are out of stock at my university’s circuit shop. Read the data sheets for the devices first then ask a question based on what you don’t understand. Help with decade counter Posted by CaptainPrice in forum: It sounds like switch or contact bouncing. Yes, my password is: But they refer to them as “set-to-nine” inputs Also, I dont see any decoupling capacitors on the IC.

You would have to figure out how to asynchronously reset the ’93 so you don’t get counts 0xA and above.

Your circuit is suffering from the dreaded “switch bounce”.


Apr 11, 3, 1, Quote of the day. If you are datashwet to have it count to 15 rather than 9 then it will work fine.

There are also two “Set-to-nine” inputs on dztasheet 74LS90 used to set its value directly to 9, these should datasyeet been tied low if you didn’t need them but should be left unconnected on the 74LS 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.

I’m trying to build a 74l93n that counts the number of pulses and displays it on a seven segment display. When the counter reaches 9 you want the next count to change it to Home Questions Tags Users Unanswered. Chris vd Merwe 3 2.

Jul 26, 2, The question is about substituting with a 74LS93 and those only have Reset pins there are no set-to-nine pins on that device.

After i finished doing all the truth tables and drawing the logic diagram, i decided to simulate it first before getting datassheet any hardware stuff.

Question regarding 74ls90’s and 74ls93 Ask Question. Dec 5, 5, Post as a guest Name. Is it possible to datadheet use the 74ls93 in a basic counter circuit? 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 Email Required, but never shown. They have supplied me with a 74ls93 however, and said that it should work with this.

Read up on the problem and various solutions here: By the way, “switch bounce” is not always “dreaded”. Oct 11, 2. Yes, it’ll work to a point – specifically, until the count reaches 9. Oct 5, 18 1.

Voltage and Current Dividers: The OP can’t get a 74LS Finbarr 3, 1 9 Actually they are Reset inputs and they could be quite useful see Spehro’s comment. Oct 11, 1. You May Also Like: It depends on if you dataseet have it roll from 9 to back to 0 on the next count.
