Latch & F.F

[jatin7797]

Latch has level sensitive control which means that its o/p is constantly affected by i/p as long as clk signal is asserted. So when the latch is enabled, its content changes immediately when its i/p change.

F.F changes its o/p only at rising or falling edge of the clk signal. After the rising or falling edge of the clk, the F.F content remains constant even if i/p changes.

NOTE- In general latches are more difficult to use because the timing considerations are much more complex.

Depending on certain cases design could benefit using either latches or F.F.

Ques: Latch is sensitive to glitch but F.F is not, is that true ? or both latches & F.F are sensitive to glitches.
