I'm having trouble understand exactly how to use flip flops, what they are doing, and how to implement them in a practical application. I understand combinational logic, boolean algebra, etc. I just want a very basic explanation of what a flip flop does, for example a D flip flop vs a JK flip flop.

 

Does volume IV chapter 10 of the All About Circuits ebook help?

 

I did not know this forum had that kind of resource O_O. I will post again after I review that section.

 

well, j/k flip flops are used in things like shift counters... when J and K are high it toggles back and forth between high and low. i worked with them alot on the ships clocks you chain them togoether, every time it goes from high to low, the next counter goes up by one.. and so on and so forth

D flip flips are more for data memory.. stores whatever is on D.. it is usaully used with a clock or enable..in this case, it only remembers the D input if the clock or enable is enabled...
