CD4013BE consists of two identical, independent data type flip-flops. Each flip-flop has independent data, set, reset, and clock inputs and Q and Q outputs. These devices can be used for shift register applications and, by connecting the Q output to the data input, for counter and switching applications.
The logic level present at input D is the positive ongoing transition of the clock pulse. It is transferred to Q output during Setting or resetting is independent of the clock and is achieved by a high level on the set or reset line respectively.
