The SN54/74LS76A offers individual J, K, Clock Pulse, Direct Set and Di- rect Clear inputs. These dual flip-flops are designed so that when the clock goes HIGH. The SN74LS76A offers individual J, K, Clock Pulse, Direct Set and. Direct Clear inputs. These dual flip-flops are designed so that when the clock goes HIGH, the . SN is a dual in-line JK flip flop IC, i.e. it has two JK flip flops inside it and each can be used individually based on our application.

The JK flip flops are considered to be the most efficient flip-flop and can be used for certain applications on its own.

The term JK flip flop comes after its inventor Jack Kilby.

The 9V battery acts as the input to the voltage regulator LM The complete working and all the states are also demonstrated in the Video below. The truth tables are correct from practical datashset of view. The latches can also be understood as Bistable Multivibrator as two stable states.

J-K Flip-Flop

A demonstration Video is also given below:. Note that the outputs feed back to the enabling NAND gates. Tactile Switch — 4No. A demonstration Video is also given below: A simplified version of the versatile J-K flip-flop. The flip-flops are also called as latching devices meaning it can remember one single bit of data and latch the output based on it, due to this property they are commonly used as daasheet registers, control registers, storage registers or where ever a small memory is required.

The remaining states are No change states during which the output will similar to previous output state. The output toggle from the previous state to another state and this process continues for each clock pulse. The LEDs used are current limited using Ohm resistor.

The working can be verified with the truth table. Submitted by admin on 17 July The JK flip flop is considered to be more suitable datsheet practical application because of its truth table that is the output of the flip flop will be stable for all types of inputs. Also we have used LED at output, the source has been limited to 5V to control the supply voltage and DC output voltage. The “enable” condition does not datashet through the entire positive phase of the clock.

The inputs are labeled J and K in honor of the inventor of the device, Jack Kilby.

Below snapshot shows it. Thus, JK flip-flop is a controlled Bi-stable latch where the clock signal is the control signal.


The reset button should be pulled up through a 1K resistor and when grounded will reset the flip-flop. The same can be verified with the truth table. This has been an added advantage. Thus, the initial state according to the truth table is as shown above.

SN JK Flip Flop Pinout, Features, Equivalent & Datasheet

Another way to look at this circuit is as two J-K flip-flops tied together with the second driven by an inverted clock signal. Log in or register to post Comment.

TL — Programmable Reference Voltage. The name JK flip-flop is termed from the inventor Jack Kilby from texas instruments. If J and K are different then the output Q takes the value of J at the next clock edge.

It can also act as a T flip-flop to accomplish toggling action if J and K are tied together. In asynchronous data transfer, a transfer pulse may be applied at any time to force the data onto the asychronous set and clear inputs, storing the data regardless of what is happening on the flipp inputs.

The term digital in electronics represents the data generation, processing or storing in the form of two states.
