A SR latch (R1, R2 = 1 kΩ; R3, R4 = 10 kΩ)In electronics, flip-flops and latches are circuits that have two stable states that can store state information – a bistable multivibrator.
Low power flip-flops [1] are flip-flops that are designed for low-power electronics, such as smartphones and notebooks. A flip-flop, or latch, is a circuit that has two stable states and can be used to store state information.
Synchronizers may take the form of a cascade of D flip-flops (e.g. the shift register in Figure 3). [7] Although each flip-flop stage adds an additional clock cycle of latency to the input data stream, each stage provides an opportunity to resolve metastability. Such synchronizers can be engineered to reduce metastability to a tolerable rate.

It is the essential characteristic of the flip-flop, a circuit which is a fundamental building block of computers and some types of semiconductor memory. A bistable device can store one bit of binary data, with one state representing a "0" and the other state a "1".
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.
A 14-year-old boy is in a serious condition in hospital following a stabbing in the West Midlands. Police said they were called to Brunel Road, Oldbury, in the early hours, after he was found with ...
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.
