This input is used for datasheeet 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.

Pin 7 is the ground or negative supply input of the IC. The set up shown can be simply built with the help of the diagram.

For other configurations this input is terminated to any of the logic levels, i. 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.

Set and Reset Inputs Pins 4, 6 and 10, 8: Gently adjust and fix the IC on the veroboard somewhere over the center of the board by soldering. Complementary Ouputs Pins 1, 2, and 13, 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.

Following conventional safety standards, primarily these dataeheet also need to be assigned to a logic level, preferably to the ground terminal for the present IC, via sufficiently high value resistors. Pinouts of the IC The D-type blocks consist of four inputs, explained as follows: Clock Input Pins 3 and The IC can be also effectively used for switching any load through input signals received from a sound sensor.

Positive input Pin Here we can see how the above discussed operating principle of the IC is practically set up for a useful purpose. Pressing S2 now, just flips the status of the output to its original position. D-type flip flops refer to circuits which may have a couple of outputs that change or toggle datasehet in response to triggers applied at the input terminals.

Yet another important feature of the IC which enables the bistable operation through two different inputs. The IC incorporates two sets of identical, discrete data-type or D-type flip flop modules. Data Input Pins 5 and 9: 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.

The circuit shown can be used for toggling any load simply by touching the touch pad.

The astable clocks can be witnessed through LED1. The signal may be applied externally through a transistor astable multivibrator 40227 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. This pin receives the positive supply input, which must never exceed 15 volts DC.
