D Flip Flop Pin Diagram. Pin 1 clear 1 input pin 2 d1 input pin 3 clock 1 input pin 4 preset 1 input pin 5 q1 output pin 6 complement q1 output pin 7 ground pin 8 complement q2 output pin 9 q2 output pin 10 preset 2 input pin 11 clock 2 input. Here we have used ic hef4013bp for demonstrating d flip flop circuit which has two d type flip flops inside.
The operation of d flip flop is similar to d latch. All these flip flops are synchronous with each other since the same clock signal is applied to each one. Apart from being the basic memory element in digital systems d flip flops.
The 74ls74 pinout diagram is as shown in the picture below.
This circuit has single input d and two outputs q t q t. Out of these 14 pins six pins are assigned for each d type ff. D flip flop circuit diagram and explanation. But this flip flop affects the outputs only when positive transition of the clock signal is applied instead of active enable.
