The problems with S-R flip flops using NOR and NAND gate is the invalid state. This problem can be overcome by using a bistable SR flip-flop that can change outputs when certain invalid states are met, regardless of the condition of either the Set or the Reset inputs. For this, a clo...
SR Flip Flop to D Flip Flop As shown in the figure, S and R are the actual inputs of the flip flop and D is the external input of the flip flop. The four combinations, the logic diagram, conversion table, and the K-map for S and R in terms of D and Qp are shown below. SR...
Figure 1: Latch R-S Flip Flop Using NAND and NOR Gates To describe the circuit of Figure 1(a), assume that initially both R and S are at the logic 1 state and that output is at the logic 0 state. Now, if Q = 0 and R = 1, then these are the states of inputs of gate B...

Circuit Diagram We know that the SR flip-flop requires two inputs, i.e., one to "SET" the output and another to "RESET" the output. By using an inverter, we can set and reset the outputs with only one input as now the two input signals complement each other. In SR flip flop, ...
Circuit Diagram D Latch TheD latchis the same asD flip flop. The only difference between these two isthe ENABLEinput. The output of the latch is the same as the input passed to theDatainput when theENABLEinput set to 1. At that time, the latch is open, and the path is transparent ...
