Functional Description:
A circuit that can store one bit of data is called a D flip-flop. It may either provide HIGH or LOW output.
As the clock switches from LOW to HIGH, the output adapts to whatever is on the data (D) input. Also referred to on the rising edge of the clock. (Some D flip-flops, on the other hand, alter on the falling edge.)
The D flip-flop only analyzes what is on the data (D) input at the precise instant when this transition occurs, according to this.
Certain D flip-flops only alter their output when the clock swings from HIGH to LOW because they have an inverted clock input. On the falling edge is the term used to describe this.
Furthermore, the CD4013's D flip-flops feature Set (S) and Clear (C) pins. Irrespective of the clock, these can be utilized to either reset the output to LOW or set it to HIGH.
