What is a Latch?
A latch is a device that has two stable states namely high output as well as low-output and includes a feedback lane also latch is a memory device used to store one bit of data. These are the same as flip-flops, but they are not synchronous devices and They do not work on the edges of the clock as Flip-flop
What is a Flip-Flop?
A Flip-Flop is a couple of latches, and the designing of this can be done using a NOR gate or a NAND gate. so it has 2 inputs, 2 outputs, a set as well a reset. it’s used to store the binary values. A Flip-Flop will have an extra CLK signal to make it work in a different way as compared to the latch.
|1||Flip-flop has two stable states that are represented as 0 and 1. also called a bistable device||The latch is also a bistable device whose states are also represented as 0 and 1.|
|2||It is an edge-triggered device.||It is a level-triggered device.|
|3||A flip-flop can be clocked for all time||A Latch may be clockless or clocked|
|4||Gates like NOR, NOT, AND, and NAND are building blocks of flip-flops.||These are also made up of gates.|
|5||They are classified into asynchronous or synchronous flip-flops.||There is no such classification in latches.|
|6||It forms the building blocks of many sequential circuits like counters.||These can be used for the designing of sequential circuits but are not generally preferred.|
|7||Flip-flops always have a clock signal||The latch doesn’t have a clock signal|
|8||Flip-flops can be built from Latches||Latches can be built from gates|
|9||Example: D Flip-flop, JK Flip-flop #||Example: SR Latch, D Latch|
