Below are the pin diagram and the corresponding description of the pins. T s input needs to be stable before trigger hold time. Whenever the clock signal is LOW, the input is never going to affect the output state. Note Q2 is a D flip-flop, Q1 is a T flip-flop. designed. The excitation table is constructed in the same way as explained for SR flip flop. digital-logic flipflop state-machines. So, JK flip-flop can be used for one of these four functions such as Hold, Reset, Set & Complement of present state based on the input conditions, when positive transition of clock signal is applied. T flip-flop is the simplified version of JK flip-flop. Gated D flip flop or also known as level triggered D flip flop has an extra control input known as “Enable” or “clock” input. Here, we considered the inputs of JK flip-flop as J = T and K = T in order to utilize the modified JK flip-flop for 2 combinations of inputs.
