_{So my question is their designs seem pretty same, what cause them to work different in their designs, how can they work different despite having the same design?}

I heard that the main difference between latch and flip flops is that latches are asynchronous while flip flops are edge triggered which makes sense. But when I check out their shematic they seem pretty much Here is the design of a dlatch from one book which I can understand CLK 11 01010 Figure 3.7 D latch: (a) schematic, (b) truth table, (c) symbol But here is the D Flip Flop shematic I found in various tutorials Q(t) cik- Q(t)
