A latch and a flip-flop are both types of circuit elements used in digital electronics to store binary data.
A latch is a type of circuit that can be used to store a single bit of data and has two inputs, SET and RESET, that determine its output state. A latch will hold its output state as long as the power is applied, regardless of the state of its inputs.
A flip-flop, on the other hand, is a type of circuit that can also store a single bit of data and has a clock input, which is used to control when the output state changes. Unlike a latch, the output state of a flip-flop will only change in response to a change in the clock signal, not in response to changes in its inputs.
In summary, a latch is an asynchronous circuit that holds its output state based on its inputs, while a flip-flop is a synchronous circuit that holds its output state based on the state of its inputs and the state of its clock signal.
