Question

DESCRIBE THE DIFFERENCES BETWEEN A LATCH AND AN EDGE-TRIGGERED FLIP-FLOP?

Explanation / Answer

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. Both the flip-flop and latch are Sequential circuits.... 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. A: A flip-flop can be set reset and pass date with a clock a latch is a two state switch of or on A flip flop will follow a clock a latch will remain status quo until it is unlatch. basically one does not use flip flop for latches and viceversa. both can be flip and latched by signals.
