JK Flip Flop - Basic Introduction

This electronics video tutorial provides a basic introduction into the operation of the JK Flip Flop circuit which uses 2 two-input NAND Gates and 2 three-input NAND Gates. The JK Flip Flop circuit is an extension of the SR latch circuit with two additional NAND gates and a clock input. The invalid condition of the SR latch circuit is no longer an issue with the JK Flip Flop. When both J and K inputs are high with an active clock input, the output toggles back and forth between ON and OFF states.

Just had to say after 12 long years I graduated and got accepted to a bachelor program in commerce and I could never have done it without you. Thank you. Truly

[beakless_duck]

I've dropped out of electrical engineering a while ago, but I will forever be grateful to you for helping me get through my circuits analysis class. Wish this was around back then to help me out with electronics too!

[varpower]

Give this guy a gold medal 🏅. Since i was in 1st grade i watched your videos. Today I'm in the last grade. Keep up with the good videos bro💯.

[emmas]

dude how do you have videos on literally everything. thank you for your service lol

[zeno]

This video helped me out so much with understanding this really confusing thing, thank you so much, I'll forever be grateful for your videos!

[harmonyOfEureka]

The best JK flip-flop explanation ever

[talashpeygir]

You explained in a patiently and clearly, well organized manner that is realy awesome thank you so

[SultanbinZ]

one day, when I finally become an eengineer, I will try to meet with you, to thank you for all the years that you’ve been there for me and I will hug you

[Teddy-Cool]

Thanks a bunch, excellent lecture! After years in chemical processing I know what a flip-flop is for, but how it works? Good job I daresay.

[ryukijifarudimo]

really thanks to you, we want more videos about Electronics and Eectrical engineering.

[guccininja]

this guy might be the greatest of all time

[plub]

Thank you very much I just have an exam today your videos save me a bunch of times lmao.

[HealthFactoryOfficial]

thank you much now I understand the whole process... You also gained a sub.

I'm gonna be honest with you, you explained this very well. And thank you so much for taking your time to make sure we understand.

[studyhard]

At 4:38, you said the output would be 0 but it will actually be 1

[Abssi]

Thank you very much, professor, and please complete all the flip flops and counters

[mohamedjohnkargbo-debrain]

Waw. I wish I had seen this video when I was in year 2. But I still learn new things though. #MyMentor

[alifaisal]

4:34 he meant the output will be 1 when one of the values is different in the input.

[letswaitdays]

No other way I’d rather start my morning 🙏

[shishir]

Tutor, please make videos on all the other flip-flops and registers and counters and the entire electronics🥺❤️

[Chen-vwnc]

I hope you will make a video on deriving T flip flop and D flip flop from the JK flip flop
