The IC 4013 incorporates two sets of identical, discrete data-type or D-type flip flop modules.
Each module is further equipped with a group of pin-outs, assigned as data, set, reset, clock inputs, and a couple of complementary outputs, Q and Q‾.
D-type flip flops refer to circuits which may have a couple of outputs that change or toggle states in response to triggers applied at the input terminals.
They are electronic circuits with two stable states used to store binary data.
Such a circuit has one or more control inputs and one or two outputs. By applying varying input, the data stored can be changed.
The CD4013 or IC-4013 is a CMOS logic chip with two D-Type (DATA) Flip-flops. A clock pulse flow to C (clock pin), will store the data at the D input. Connect clock and both Q output to make a toggle flip-flop for counting.
