Clock Datasneet Pins 3 and Positive input Pin Here we can see how the above discussed operating principle of the IC is practically set up for a useful purpose. Gently adjust and fix the IC on the veroboard somewhere over the center of the board by soldering.

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 circuit datashret can be used for toggling any load simply by touching the touch pad. Pin 7 is the ground or negative supply input of the IC.


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

This pin dayasheet the positive supply input, which must never exceed 15 volts DC.

The IC can be also effectively used for switching any load through input signals received from a sound sensor. The diagram illustrates how a IC may be set up for testing adtasheet fundamental bistable operation and how it can be further applied for practical uses.

The set up shown can be eatasheet built with the help of the diagram. Data Input Pins 5 and 9: The astable clocks can be witnessed through LED1. Complementary Ouputs Pins 1, 2, and 13, Set and Reset Inputs Pins dafasheet, 6 and 10, 8: Pressing S2 now, just flips the status of the output to its original position. This input is used for receiving clock signals which are normally in the form of square waves. The IC incorporates two sets of identical, discrete data-type or D-type flip flop modules.

Pinouts of the IC The D-type blocks consist of four inputs, explained as follows: For other configurations this input is terminated to any of the logic levels, i. The signals produces a bistable effect over one of the free outputs, the other being connected to the Data input as explained above.

The sets of outputs change ci 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.

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.

After 40027 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.
