what is differnce betn. a latch and flip flop?

Answer 1

Latch is a level sensitive device while flip-flop is an edge sensitive device.
Latch is sensitive to glitches on enable pin, whereas flip-flop is immune to glitches.
Latches take less gates (also less power) to implement than flip-flops.
Latches are faster than flip-flops.

Answer 2

latches and flip-flops are the building blocks of sequential circuits. While gates had to be built directly from transistors, latches can be built from gates, and flip-flops can be built from latches. This fact will make it somewhat easier to understand latches and flip-flops.
Both latches and flip-flops are circuit elements whose output depends not only on the current inputs, but also on previous inputs and outputs. The difference between a latch and a flip-flop is that a latch does not have a clock signal, whereas a flip-flop always does.

Latches are asynchronous, which means that the output changes very soon after the input changes

A flip-flop is a synchronous version of the latch

Answer 3

They both store digital information. Typically, a latch is sensitive to a clock level. That is as long as the clock is held in the active state, the input will propagate to the output. Flops are usually edge triggered. That is, the input is stored on a rising or falling edge of the clock.

Answer 4

A latch remembers the prior state of a signal. A flip-flop can toggle to either opposite state on the arrival of a signal (clock), which latches aren't ordinarily designed to do.

Answer 5

latch produces the same output as its input (0 gives 0 and 1 gives 1).. flip flops are basically classified in to four types viz. t-flipflop,d-flip flop, r-s flipflop & j-k flipflop... d-flipflop is similar to a latch.. toggle(flipflop) toggles 1-input to 0-output and viceversa..

Answer 6

The basic difference is a latch can "remember " its previous state (0,1, undefined) while a flip-flop can't
