# Circuit Diagram Of J K Flip Flop | Diandra Wiring Diagram Sequential circuit design using JK Flip flops using state diagram, excitation tables, K Maps, and Boolean expression.

J-K Flip Flop. The circuit includes two 3-input AND gates. The output Q of the flip flop is returned back as a feedback to the input of the AND along with other inputs like K and clock pulse [CP]. So, if the value of CP is '1', the flip flop gets a CLEAR signal and with the condition that the value of Q was earlier 1.

It can be seen above, that the external clock pulses (pulses to be counted) are fed directly to each of the J-K flip-flops in the counter chain and that both the J and K inputs are all tied together in toggle mode, but only in the first flip-flop, flip-flop FFA (LSB) are they connected HIGH, logic "1" allowing the flip-flop to toggle on every clock pulse.

Table 3. State diagrams of the four types of flip-flops. You can see from the table that all four flip-flops have the same number of states and transitions. Each flip-flop is in the set state when Q=1 and in the reset state when Q=0. Also, each flip-flop can move from one state to another, or it can re-enter the same state.

JK FLIP-FLOP: The JK flip flop (JK means Jack Kilby, a Texas instrument engineer, who invented it) is the most versatile flip-flop, and the most commonly used flip flop. Like the RS flip-flop, it has two data inputs, J and K, and an EN/clock pulse input (CP). Note that in the

The working of these circuits can be done by utilizing previous circuit input, CLK, memory, and output. This article discusses an overview of the master-slave flip flop. But before going to know about this flip-flop, one has to know about the basics of flip-flops like SR flip flop and JK flip flop. What is a Master-Slave Flip Flop?
