Flip Flops FAQ

What is the function of the Schmitt-trigger inputs?

The Schmitt-trigger inputs filter out noise and slow-rising signals, ensuring clean switching transitions for the flip-flops.

How does the master reset affect the outputs?

Activating the master reset forces all six flip-flop outputs to a low state regardless of the clock or D-input states.
