Quadruple D-type flip-flop
DESCRIPTION
The HEF40175B is a quadruple edge-triggered D-type
flip-flop with four data inputs (D0to D3), a clock input (CP),
an overriding asynchronous master reset input (MR), four
buffered outputs (O0to O3), and four complementary

buffered outputs (
transferred to O0to O3on the LOW to HIGH transition of
CP if MR is HIGH. When LOW, MR resets all flip-flops
(O0to O3= LOW, O0to O3= HIGH), independent of CP
and D0to D3.
