Clock Input Pins 3 and Pin 7 is the ground or negative supply input of the IC. 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.

The astable clocks can be witnessed through LED1. Pressing S2 now, just flips the status of the output to its original position. Complementary Ouputs Pins 1, 2, and 13, This input is used for receiving clock signals which are normally in the form of square waves. 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.


Gently adjust and fix the IC on the veroboard somewhere over the center of the board by soldering.

Understanding IC Pin-Outs and Specifications – Datasheet and Application Circuits Explained

Set and Reset Inputs Pins 4, 6 and 10, 8: Positive input Pin For other configurations this input is terminated to any of the logic levels, i. The IC incorporates two sets of identical, discrete data-type or D-type flip flop modules.

The signals produces a bistable effect over one of the free outputs, the other being connected to the Data input as explained above. Yet another important feature of the IC which enables the bistable operation through two different inputs. 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.

The IC can be also effectively used for switching any load through input signals received from a sound sensor. The circuit shown can be used datasneet toggling any load simply by touching the touch pad.

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.


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 any instant. The signal may be applied externally through a transistor astable multivibrator or more conventional types using NAND gates or NOR gates.

Here we can see how the above discussed operating principle of the IC is practically set up for a useful purpose. Pinouts of the IC The D-type blocks consist of four inputs, explained as follows: This pin receives the positive supply input, which must never exceed 15 volts DC.

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. Data Input Pins 5 and 9: The set up shown can be simply built with the help of the diagram.
