A flip-flop is an electronic circuit with two stable states that can store binary data. You can change the stored data by applying a variety of inputs.
A T flip flop is just like JK flip-flop. These are a single input version of JK flip flop. You can get the changed form of JK flip flop by connecting both inputs J and K. This flip-flop has only one input along with the clock input.
We call these flip-flops as T flip-flops because of their ability to complement its state (i.e.) Toggle, hence the name Toggle flip-flop.

T Flip-flop Circuit Diagram
The IC power source VDD ranges from 0 + 7V and data provided in the datasheet. The following snapshot shows it. Also, we have used LED on the output; it has limited the source to 5V to control the supply voltage and DC output voltage. We have used the LM7805 regulator to limit the LED voltage.
