How does the triggering mechanism differ between a latch and a flip-flop in digital circuits?
Question

How does the triggering mechanism differ between a latch and a flip-flop in digital circuits?

A.

A latch is triggered by clock edges, while a flip-flop is controlled by enable signals.

B.

A latch updates output only at the rising edge of a clock pulse, whereas a flip-flop responds throughout the clock cycle.

C.

A latch is level-triggered, while a flip-flop is edge-triggered.

D.

A latch stores data permanently, while a flip-flop stores data temporarily.

Correct option is C

Explanation Latches respond to the level (HIGH or LOW) of an enable or clock signal.They remain transparent as long as the enable level is active. Flip-flops change their output only on a specific clock edge(rising edge or falling edge).Thus, the key distinction in triggering is:Latch  Level-triggeredFlip-flop  Edge-triggered\textbf{Explanation} \\[6pt]\bullet \ \textbf{Latches} \text{ respond to the } \textit{level} \text{ (HIGH or LOW) of an enable or clock signal.} \\[2pt]\quad \text{They remain transparent as long as the enable level is active.} \\[6pt]\bullet \ \textbf{Flip-flops} \text{ change their output only on a } \textit{specific clock edge} \\[2pt]\quad \text{(rising edge or falling edge).} \\[8pt]\text{Thus, the key distinction in triggering is:} \\[6pt]\text{Latch } \rightarrow \text{ Level-triggered} \qquad \text{Flip-flop } \rightarrow \text{ Edge-triggered}​​
