The T flip-flop (Toggle flip-flop) is a type of flip-flop that changes its output state on each clock pulse if the input is set to 1. It is derived from the JK flip-flop, with both J and K inputs tied together and referred to as the T input.

Key Features:

• T (Toggle) Input: The single input for the flip-flop. When T = 1, the output toggles (changes state). When T = 0, the output remains the same.
• Clock Input: The T flip-flop is edge-triggered, meaning it only responds to the T input when there’s a rising or falling edge of the clock signal.
