[edit] D flip-flop


D flip-flops are by far the most common type of flip-flops
and some devices (for example some FPGAs) are made entirely
from D flip-flops. They are also commonly used for shift-
registers and input synchronisation.

[edit] JK Flip-flop
.. As the behavior of the JK flip-flop is completely
predictable under all conditions, this is the preferred
type of flip-flop for most logic circuit designs.
