Find the PDF Datasheet, Specifications and Distributor Information. Each of these monolithic counters contains four master- slave flip-flops and additional gating to provide a divide-by- two counter and a three-stage binary.

Also, it would be interesting 47ls93n know whether your 7-segment display will properly display digits above 9 or if it will display nonsense. Home Questions Tags Users Unanswered. Email Required, but never shown. When the counter reaches 9 you want the next count to change it to There are also two “Set-to-nine” inputs on the 74LS90 used to set its value datashete to 9, these should have been tied low if you didn’t need them but should be left unconnected on the 74LS The 74LS93 is a binary counter, so it will carry on past 9 and count up to 15 F in hexadecimal or in datashdet.

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

Read the data sheets for the devices first then ask a question based on what you don’t understand. Entrepreneur 2 5. Mar 24, 21, 2, I’m trying to build a circuit that counts the number of pulses and displays it on a seven segment display.

Oct 13, 7. Voltage and Current Dividers: Actually they are Reset inputs and they could be quite useful see Spehro’s comment. datasneet

Oct 11, 3. Jul 17, 22, 1, By the way, “switch bounce” is not always “dreaded”. Do you already have an account? Good point, Tut – guess they’re not going to be useful after all.

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 It sounds like switch or contact bouncing. Your name or email address: Dec 5, 5, But they refer to them as “set-to-nine” inputs You May Also Like: Jul 26, 2, Quote of the day. 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.

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.

It depends on if 74ld93n must have it roll from 9 to back to 0 on the next count. Oct 11, 4. Help with counter circuit?

Also, I dont see any decoupling capacitors on the IC. Apr 11, 3, 1, By clicking “Post Your Answer”, you dahasheet that you have read our updated terms of serviceprivacy policy and cookie policyand that your continued use of the website is subject to these policies.

They have supplied me with a 74ls93 however, and said that it should work with this. That will probably confuse whatever you’re using to display the result and will prevent you properly cascading multiple counters to produce displays with more than one digit. Post as a guest Name. Yes, it’ll work to a point – specifically, 74ls93nn the count reaches 9.

The OP can’t get a 74LS
