Dual Flip-Flop

4HP eurorack module version of the classic 4013 CMOS IC.

Two independent D-type flip-flops with SET, RESET, CLOCK, and DATA inputs and complementary outputs.

On the rising edge of a signal applied to CLK the binary data present on D is transferred to Q, and the complement appears at Q.

Positive signal applied to S forces Q high and Q low.

Positive signal applied to R forces Q low and Q high.

If S and R are high at the same time Q and Q will both be high.

CLK and D have no effect on the outputs while either S or R are high.

not-Q is normalled to the D input of each flip-flop for easy dividing by 2 using just the CLK input (simple sub octave!).

Really basic utility module with many uses from LFO/clock to audio rate.
