Difference between Latches and Flip- Flops
A Latch is an electronic device that instantly changes its output based on the applied input. We use latch to store either 0 or 1 at any specified time. The "SET" and "RESET" are two inputs in a latch, and there are two outputs that are complement to each other. We use latch to store one bit of data and it is a memory device. A latch is just like a flip-flop, but latch is not a synchronous device. The Latch does not work on the clock edges like the flipflop.
Flip-flop is a digital memory circuit, and with the help of the flip-flop we can store one bit of information. The fundamental blocks of various sequential circuits are flip-flops. Flip-flop is also called a bistable multivibrator or one-bit or binary. In a sequential circuit, we use flip-flops as a memory element.
In a sequential circuit, the output is obtained from the combinational circuit or flip-flop or both. When the clock pulse is active, then the state of the flip-flop is active, and when the clock pulse is not active, then the state of the clock pulse remains unaffected. Mainly, in the synchronous sequential circuit, flip flops function as a memory element, and in asynchronous sequential circuit, the unclocked flip flops or latches function as a memory element.
Mostly, there are four types of Flip-Flops:
- Set-Reset (SR) Flip-Flop
- JK Flip-Flop
- D (Data or Delay) Flip-Flop
- T (Toggle) Flip-Flop
Difference Between Latch and Flip-Flop
|1.||A Latch is a bistable device, and the state of the latch is represented as 0 and 1.||Flip-Flop is also a bistable device and there are two stable states of Flip-Flop, which are represented as 0 and 1.|
|2.||A Latch is a level triggered device.||Flip-flop is an edge triggered device.|
|3.||We cannot classify the Latch.||We can classify the flip-flop as synchronous or asynchronous flipflops.|
|4.||To form sequential circuits, latches are constructed from logic gates.||To form sequential circuits, Flip-Flop is constructed from latches along with an additional clock signal.|
|5.||Latches are fast as compared to the Flip-Flop.||Flip-Flops are slow as compared to the latches.|
|6.||Less power is consumed by the Latches.||More power is consumed by the Flip-Flop.|
|7.||The latches can be clocked or clockless.||For all the time, Flip-Flops are clocked.|
|8.||Only binary inputs can be used to operate the latches.||By the clock signal and binary input, the Flip-Flop works.|

|10.||The latch cannot be used as a register because the register requires more advanced electronic circuits where time plays an essential role.||Flip-Flop can work as a register because it contains clock signals in its input.|
|11.||The latch is asynchronous because latch does not work on the basis of the time signal.||Flip-Flop is synchronous because flip-flop work on the basis of the clock signal.|
|12.||The latch cannot be built from the gates.||Flip-Flop cannot be built from the latches.|
