WebJul 30, 2024 · A Digital Counter is obtained by arranging the flip-flops. These are the applications of flip-flops. Other than counting, these are used for measuring the … WebDec 27, 2024 · The above circuit diagram represents a 3-bit Johnson counter using a 7474 D flip-flop. You can easily extend this circuit up to 4-bit, 5-bit, etc. by adding flip-flops after the 3rd flip-flop. A single 7474 IC consists of 2 flip-flops. So you need two 7474 ICs for implementing the Johnson ring counter.
