D Type Flip Flop. See the newest logic products from TI, download Logic IC datasheets, application notes, order free samples, and use the quick search tool to easily find the best logic solution. The successive clock pulses would make the bistable toggle one time for every two clock cycles.

The D stands for "data"; this flip-flop stores the value that is on the data line. A D-type flip-flop can have two possible. At the rising, or positive, edge of the clk signal the D-FF samples d and sets that as its output q.
The second flip-flop. sets its output depending on the D input.
D Flip Flop from NAND Gates (Clocked) Now, here, we show a synchronous, or clocked, D flip flop.
Output Q goes to the opposite state. As a sequential circuit, it of course requires a clk port. This Flip Flop is also called a delay flip flop because when the input data is provided into the d flip-flop, the output follows the input data delay by one clock pulse.
