Hello, I was curious about latches, I was thinking, a latch that is "clocked", that just puts the input on the output when receives a 0 to 1 border or 1 to 0 border would be better for my project (not transparent latch).

I was reading this:
http://en.wikipedia.org/wiki/Latch_(electronic)
But couldnt figure out what type is this I'm wanting, or even if it exists.

Does this type of latch exists? What's the most commom CI like this?

Thanks.
