These devices contain two independent D-type positive-edge-triggered flip-flops. A low level at the preset or clear inputs sets or resets the outputs regardless of the levels of the other inputs. When preset and clear are inactive (high), data at the D input meeting the setup time requirements are transferred to the outputs on the positive ...

The circuit excitation table represents the present states of the counting sequence and the next states after the clock pulse is applied and input T of the flip-flops. By seeing the transition between the present state and the next state, we can find the input values of 3 Flip Flops using the Flip Flops excitation table.

Flip-flop is a digital circuit that stores a binary bit. In flip-flop the clock signal controls the state of device. It is also called as memory element or a binary storage device. These circuits have two stable states HIGH & LOW. The circuits remain in one state till the clock signals enables them to change to the other state.

The S-R flip flop is the most common flip flop used in the digital system. In SR flip flop, when the set input "S" is true, the output Y will be high, and Y' will be low. It is required that the wiring of the circuit is maintained when the outputs are established. We maintain the wiring until set or reset input goes high, or power is shutdown.

A toggle input (T) is connected in common to both the AND gates as an input. The AND gates are also connected with common Clock (CLK) signal. In the T flip – flop, a pulse train of narrow triggers are provided as input (T) which will cause the change in output state of flip – flop. So, these flip – flops are also called Toggle flip – flops.
