D Flip Flop Using 74HC74 IC

The 74HC74 is a dual D flip flop IC. Therefore at a time we can handle two bit of data with it. It have two terminal which are asynchronous and change the value of output without being effected by clock signal. These are set and reset terminals. Now Its Pin configuration

Pin	Symbol	Description
1	1 SD	Asynchronous reset direct input (active low).
2	1D	Data input.
3	1CP	Clock input
4	1SD	Asynchronous set direct input (active low).
5	1Q	Output
6	1Q	Complement Output
7	GND	Ground
8	2Q	Complement Output
9	2Q	Output
10	2SD	Asynchronous set direct input  (active low)
11	2CP	Clock input
12	2D	Data input
13	2RD	Asynchronous reset direct input  (active low)
14	VCC	Supply voltage
