whats the difference between a latch and Flip-flop?

Question

Logic Design

Answer 1

The main difference between latch and FF is that latches are level sensitive while FF are edge sensitive. They both require the use of clock signal and are used in sequential logic. For a latch, the output tracks the input when the clock signal is high, so as long as the clock is logic 1, the output can change if the input also changes. FF on the other hand, will store the input only when there is a rising/falling edge of the clock.

Answer 2

Latches are digital elements (circuits) that pass the input to the output only on application of a clock pulse. That means that the output doesnt change unless a second clock pulse is given. That also means that the data is latched at the output. Flip flops on the other hand are basic elements of sequential logic. In fact the latches are made using Flip flops. A good book for digital electronics would be Floyd.

Answer 3

A latch is one type of flip-flop; it does nothing more than to save the state of the single data input, hence is often called a D flip-flop.

This is contrasted with other varieties of flip-flops such as the J-K, where two inputs are used to provide certain sequential logic functions. Nonetheless, the J-K flip-flop can be configured to operate like a D flip-flop

Answer 4

All you need to know is that a flip-flop is synchronous with a clock, and a latch isn't. Beyond that, read the datasheet and be careful.

Answer 5

logic design
the latch and ff has the basic difference in applying clock pulse, FF may not work though it is enableed, untill and unless the clock pulses given, the laches does not require any clock pulse, it works just the enable is high
