Quadruple D-type ip-op
HEF40175B
MSI
DESCRIPTION
The HEF40175B is a quadruple edge-triggered D-type
flip-flop with four data inputs (D0 to D3), a clock input (CP),
an overriding asynchronous master reset input (MR), four
buffered outputs (O0 to O3), and four complementary
buffered outputs (O0 to O3). Information on D0 to D3 is
transferred to O0 to O3 on the LOW to HIGH transition of
CP if MR is HIGH. When LOW, MR resets all flip-flops
(O0 to O3 = LOW, O0 to O3 = HIGH), independent of CP
and D0 to D3.
