Flip Flops FAQ

What is the function of the Schmitt triggers on the inputs?

The Schmitt triggers provide hysteresis, allowing the device to accept slow or noisy input signals without causing multiple output transitions.

How does the positive-edge triggering work?

The flip-flop updates its output state based on the D input level only at the rising edge of the clock signal pulse.
