tff or jkff?
« on: March 03, 2008, 00:55:24 AM »
Is just a question.

I have seen many people that they use jk flip flop connected as a toggle flip flop. And now i wonder, is there any special reason why they use jk and not have some ready t-ff (that i know that exists) and do the same toggle job easier? And it is not a reason that they use the other jk flip flops for other reasons. I know that all flip flops are either not used or just connected as jk

This is just a question that came up to me when i was watching a project...

Sometimes TFF are not having so many functions like a jkff that is connected as tff. A jk can have also reset and set state that tff may not have.

Well, the "stock" reason looks like more real to me.  :)

I can think of nothing else and i have not find something like a document that could explain it  :-\
