The term flip-flop has historically referred generically to both level-triggered (asynchronous, transparent, or opaque) and edge-triggered (synchronous, or clocked) circuits that store a single bit of data using gates. [1] Modern authors reserve the term flip-flop exclusively for edge-triggered storage elements and latches for level-triggered ones.
Flip-flop and latch are not the same; so, they deserve separate pages (as it is). Flip-flop and latch are closely related; so, the two pages have to be closely related as well. The latch precedes chronologically the flip-flop. Eccles and Jordan have invented a latch, not a flip-flop; so, the data about their patent have to be placed on Latch.
If the output of the flip-flop is low, and a high clock pulse is applied with the input being a low pulse, then there is no need for a state transition. The extra computation to sample the inputs cause an increase in setup time of the flip-flop; this is a disadvantage of this technique. [3]
Flip-flop excitation tables [ edit ] In order to complete the excitation table of a flip-flop , one needs to draw the Q(t) and Q(t + 1) for all possible cases (e.g., 00, 01, 10, and 11), and then make the value of flip-flop such that on giving this value, one shall receive the input as Q(t + 1) as desired.
Current mode logic (CML), or source-coupled logic (SCL), is a digital design style used both for logic gates and for board-level digital signaling of digital data.. The basic principle of CML is that current from a constant current generator is steered between two alternate paths depending on whether a logic zero or logic one is being represented.

This dual threshold action is called hysteresis and implies that the Schmitt trigger possesses memory and can act as a bistable multivibrator (latch or flip-flop). There is a close relation between the two kinds of circuits: a Schmitt trigger can be converted into a latch and a latch can be converted into a Schmitt trigger.
D : Q; where Dff is the D-input of a D-type flip-flop, D is the module information input (without CE input), and Q is the D-type flip-flop output. This type of clock gating is race-condition-free and is preferred for FPGA designs. For FPGAs, every D-type flip-flop has an additional CE input signal.
