Flip-flops are elementary memory operators. Their current state, determined by the state of the outputs, is a function of the inputs and the previous state of the outputs. We present the various flip-flops based on logic gates. These flip-flops, which operate solely on logic principles, are referred to as static.
The circuit shown in figure 1 consists of two inverters in series. Figure 2 gives the static characteristics S1 (E ) and S2(E ) of the outputs S1 and S2 of the inverters made with real electrical circuits. When the output S2 is looped back to the input E1 of...
