Question

Some confusion about the difference between latches and flip/flop.
Can u tell me such a difference?

Answer 1

latches are level sensitive and flip flop are edge sensitive
Flip flops are edge-triggered devices whereas latches are level triggered devices.
latch does not have clock signal whereas flip flop does.
Flip flop has two values while latch has only one value.

Answer 2

flip flop:
-> it work's on the basis of clock pulses.
-> it is a edge trigerred , it mean that the output and the next state input changes when there is a change in clock pulse whether it may a +ve or -ve clock pulse.
latch;
-> it is based on enable function input
-> it is a level trigerred , it mean that the output of present state and input of the next state depends on the level that is binary input 1 or 0.

Answer 3

Correct ali110, ... but not complete.

Answer 4

sorry. It is not correct to say: "Flip flop has two values while latch has only one value".
What do you mean. Both have two states and are able to maintain it.

Answer 5

Flipflop- clocked latch.
latch is basic building block of a sequential ckt...the memory(stored bit) changes depending up on the input values.
In the case of large complicated circuits we cannot afford to change the stored value depending up on variations at the input.so we apply a clock signal.
Now the output depends not only on the input but also on clock signal,such clocked latches are called flipflops

Answer 6

rahul91 your response contains something usefull for the smallest and clear sentence which underlines the main difference between flip-flops and latches

Answer 7

what is?

Answer 8

The main difference between latches and flip-flops is that for latches, their outputs are constantly
affected by their inputs as long as the enable signal is asserted. In other words, when they are enabled, their content
changes immediately when their inputs change. Flip-flops, on the other hand, have their content change only either
at the rising or falling edge of the enable signal. This enable signal is usually the controlling clock signal. After the
rising or falling edge of the clock, the flip-flop content remains constant even if the input changes.

Answer 9

latch uses triggers while flip flops use clock signal

Answer 10

dirtymind say the right, clear thing. In few words: latches are "transparents", flip-flop not.
