3. D-jefa-Flop. Na'urorin na irin wannan ma da daya data (D) shigar da wakilci lokaci da bata lokaci ba.
4. DV-jawo - shi ne, a ainihi, wannan D-jefa-Flop, amma da ciwon wani ƙarin (V) sarrafa labari.
5. JK-jefa-Flop. Wannan irin na'urar bambanta daga asynchronous a cewa wani darajar da babu-RS-type na'urar haduwa ana inverted adana bayanai.
