DESCRIPTION
The HEF40174B is a hex edge-triggered D-type flip-flop
with six data inputs (D0to D5), a clock input (CP), an
overriding asynchronous master reset input (MR), and six
buffered outputs (O
0
to O5). Information on D0to D5is
transferred to O0to O5on the LOW to HIGH transition of
CP if MR is HIGH. When LOW, MR resets all flip-flops
(O0to O5= LOW) independent of CP and D0to D5.
