The difference between latches and flip flops is shown
|
Latches |
Flip Flops |
|
Latches are building block of sequential circuits and they are built using logic gates |
Flip flops are also building blocks of sequential circuits but they are made using latches |
|
Latches continuously changes input and output changes correspondingly |
Flip flop output changes only when clock is applied |
|
Latches are level sensitive |
Flip flops are edge sensitive |
