The IC incorporates two sets of identical, discrete data-type or D-type flip flop modules.

CD4027 – Dual JK Flip Flop

D-type flip flops refer to circuits which may have a couple of outputs that change or toggle states in response to triggers applied at the input terminals. Complementary Ouputs Pins 1, 2, and 13, The sets of outputs change states when operated in the bistable mode or while setting and resetting the IC, always producing opposite logic levels at datasheer instant.

Data Input Pins 5 and 9: For other configurations this input is terminated to any of the logic levels, i.

Clock Input Pins 3 and This input is used for receiving clock signals which are normally in the form of square waves. The signal may be applied externally through a transistor astable multivibrator or more conventional types using NAND gates or NOR gates. The signals produces a bistable effect over one of the free outputs, the other being connected to the Data input as explained above.

Set and Reset Inputs Pins 4, 6 and 10, 8: Following conventional safety standards, primarily these inputs also need to be assigned to a logic level, preferably to the ground terminal for the present IC, via sufficiently high value resistors. Positive input Pin This pin receives the positive supply input, which must never exceed 15 volts DC. Pin 7 is the ground or negative supply input of ratasheet IC. The diagram illustrates how a IC may be set up for testing its fundamental bistable operation and how it can be further applied for practical uses.

Gently adjust and fix the IC on the veroboard somewhere over the center of the board by soldering. After all the connections are made, have a quick glance and make sure that all have been wired as per the diagram, if possible brush-clean the solder side with thinner.

CD – Dual JK Flip Flop

The astable clocks can be witnessed through LED1. The configurations can be repeated by connecting the modules in series for getting the time period to any desired lengths, but in multiples of two.

Yet another important feature of the IC which enables the bistable operation through two different inputs.

The set up shown can be simply built with the help of the diagram. Pressing S2 now, just flips the status of the output to its original position. The circuit shown can be used for toggling any load simply by touching the touch pad. Here we can see how the above discussed operating principle of the IC is practically set up for a useful datadheet.

The IC can be also effectively used for switching any load through input signals received from a sound sensor. Pinouts of the IC The D-type blocks consist of four inputs, explained as follows:
