Flip flop and latch difference
Difference between Latch and Flip-flop
| Latch | Flip flop | ||
| 1. | Structure- latch is purely based on blocks of logic gates
|
Flip flop made by blocks of logic gates with the use of latch.
|
|
| 2. | It does not have clock in it’s internal circuit | It has a clock with it’s internal circuit | |
| 3.
|
It checks or monitors inputs continuously and changes the output.
corresponding to inputs. |
It checks/monitors input continuously but the output changes with respect to clock signal. | |
| 4. | Latch is sensitive to input signal only. | Flip flop is sensitive to input and clock signal. | |
| 5. | Inputs can change at any time so It is level trigger | Flip flop can get triggered with some instance with clock. So Flip-Flop is an Edge trigger. | |
| 6. | It cannot be used as resistor | It can be used as resistor because it has clock in its circuit. | |
| 7. | Latch is an asynchronous circuit | Flip flop is Synchronous circuit | |
| 8. | It requires less power than Flip flop | It requires more power than latch | |
| 9.
|
Latch does not take delay to respond to output with
respect to input. So latch is faster than Flip Flop. |
Flip flop takes delay to respond output because it has input as well as clock signal. So it is Slower than Latch | |
| 10. | Circuit designing of Latch is Not complex than Flip flop | Circuit designing of Flip flop is complex than the Latch. | |
