Difference between Latch and Flip-Flop
Latch:
Latches are sequential logic circuits that designed using logic gates. It used to store binary information. These are level triggered and thus operate when they are enabled.
Flip-Flop:
A flip-flop is a binary cell capable of storing one bit of information. It has two outputs, one for the normal value and one for the complement value of the bit stored in it. A flip-flop maintains a binary state until directed by a clock pulse to switch states.
Latch vs Flip-Flop:
1. It follows level triggering approach. | 1. It follows edge triggering approach. |
2. It is designed using Logic gates | 2. It is designed using Latches with a clock |
3. Type of operation performed: Asynchronous | 3. Type of operation performed: Synchronous |
4. It requires comparatively less power. | 4. It requires more power. |
5. It is sensitive to applied input signal when enabled. | 5. It is sensitive to applied input along with clock signal. |
6. Type: S-R, J-K, T and D Latches. | 6. Type: S-R, J-K, T and D Flip flops. |
7. Latches are comparatively less robust. | 7. Flip-flops are comparatively more robust. |
8. Latches operate only using binary inputs. | 8. Flip-Flops work using the binary input and the clock signal. |
9. Circuit analysis is complex. | 9. Circuit analysis is easy. |
10. It has a comparatively fast operating speed. | 10. It has a slow operating speed. |
