Information on D0 to D5 is transferred to O0 to O5 on the LOW to HIGH transition of CP if MR is HIGH. When LOW, MR resets all flip-flops (O0 to O5 = LOW) independent of CP and D0 to D5. DESCRIPTION The HEF40174B is a hex edge-triggered D-type flip-flop with six data inputs (D0 to D5), a clock input (CP), an overriding asynchronous master reset input (MR), and six Fig.1 Functional diagram.
