Flip Flops FAQ

Are the Set and Reset inputs synchronous or asynchronous?

The Set and Reset inputs are asynchronous, meaning they operate independently of the clock signal.

What is the trigger type for data transfer?

Data is transferred to the Q output on the positive-going edge of the clock pulse.
