7.2.19 40175 (Quad D-type Flip-flop)
Quadruple D-type flip-flop truth table:
This device is a quadruple edge-triggered D-type flip-flop with four data inputs (D
0
to D
3
),
a clock input (CP), an overriding asynchronous master rest input (MR
), four buffered
outputs (Q
0
to Q
3
), and four complementary buffered outputs (Q
0
to Q
3
).

X 1 no change no change
XX0 0 1
1 = HIGH state (the more positive voltage)
0 = LOW state (the less positive voltage)
X = state is immaterial
= positive-going transition
= negative-going transition
