What is T Type Flip Flop?

The T-type flip-flop is a basic digital logic element and has a data input (T), a clock signal (clk), and an output. The T-type flip-flop basically performs a function of copying or inverting the data input to the output when a clock pulse arrives. The working principle of T type flip-flop is as follows:

It always has two states: state "0" and state "1".


Each time a clock pulse arrives, the T-type flip-flop performs the logical XOR operation between its current state and the T input. The result determines the new state.
If input T is "0", the current state is retained (state 0 remains "0", state 1 remains "1").
If input T is "1", the current state is reversed (state 0 becomes "1", state 1 becomes "0").
The T-type flip-flop is used in various digital circuits and is often used for data storage and timing functions. They are widely used, especially in applications such as digital counters and timing circuits. It can be used with other types of flip-flops such as T-type flip-flop, D-type flip-flop or JK-type flip-flop and is used to perform various logical operations.
