JK FLIP FLOP DATASHEET 7476 PDF

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 term digital in electronics represents the data generation, processing or storing in the form of kk states. An example is in which each term represents an individual state.

The latches can also be understood as Bistable Multivibrator as two stable states.

Out of the above types only JK and D flip-flops are available in the integrated IC form and also used widely in most of 77476 applications. The name JK flip-flop is termed from the inventor Jack Kilby from texas instruments. Due to its versatility they are available as IC packages.

The major applications of JK flip-flop are Shift registers, storage registers, counters and control circuits. Inspite of the simple wiring of D type flip-flop, JK flip-flop has a toggling nature. This has been an added advantage.

SN JK Flip Flop Pinout, Features, Equivalent & Datasheet

Hence they are mostly used in counters and PWM generation, etc. Whenever the clock signal is LOW, the input is never going to affect the output state.

The clock has to be high for the inputs to get active. Thus, JK darasheet is a controlled Bi-stable latch where the rlop signal is the control signal. Thus, the output has two stable states based on the inputs which have been discussed below. According to the table, based on the inputs, the output changes its state.

But, the important thing to consider is all these can occur only in the presence of the clock signal.

7476 – 7476 Dual J-K Flip-Flop Datasheet

This, works like Flup flip-flop for the complimentary inputs and the advantage is that this has toggling function. Thus, comparing the three input and two input NAND gate truth table and applying datasheeg inputs as given in JK flip-flop truth table the output can be analysed. Hence, this pin always pulled up and can be pulled down only when needed. It is a 14 pin package which contains 2 individual JK flip-flop inside.

Above is the pin diagram datawheet the corresponding description of the pins. Below snapshot shows it. Also we have used LED at output, the source has been limited to 5V to control the supply voltage and DC output voltage.

The 9V battery acts vlop the input to the voltage regulator LM Hence, the regulated 5V output is used as the Vcc and pin supply to the IC. Hence, default input state will be LOW across all the pins except R satasheet is state of normal operation. Thus, the initial state according to the truth table is as shown above. The LEDs used are current limited using Ohm resistor. A demonstration Video is also given below:. The working can be verified with the truth table. R is already Pulled up so no need to press the button to make it 1.

The same can be verified with the truth table. The output toggle from the previous state to another state and this process continues for each clock pulse. R is already Pulled up so we need to press the button to make it 0. The State 4 output shows that the input changes does not affect under this state.

The remaining states are No change states during which the output will similar to previous output state. The changes do not affect the output states, you can verify with the Truth Table above.

The complete working and all the states are also demonstrated in the Video below. Quote and Order boards in minutes on https: The truth tables are correct from practical point mk view.
