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.
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
