Hex D-type flip-flop
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

buffered outputs (O0 to O5). 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.
