Latches & Flip-Flops

Latches and flip-flops are two types of electronic circuits used in digital systems to store and manipulate digital data. They are both sequential logic circuits, meaning that they can store information and use that information to make decisions based on the previous state.

A latch is a type of digital circuit that can hold or "latch" a signal in its current state. It is a simple memory element that can store a single bit of information. A latch can be transparent or opaque, depending on its behavior when the clock signal is active. A transparent latch passes the input signal through to the output when the clock signal is active, while an opaque latch holds the input signal at the output when the clock signal is active.

Flip-flops are similar to latches but are more sophisticated and have additional control inputs. A flip-flop is a digital circuit that can store one bit of information and change its state based on the clock signal and input signals. Flip-flops can be edge-triggered or level-triggered, depending on how they respond to the clock signal. Edge-triggered flip-flops change their state at the rising or falling edge of the clock signal, while level-triggered flip-flops change their state continuously as long as the clock signal is active.

Flip-flops are classified into various types based on their behavior and the number of inputs. Some of the commonly used flip-flops include D flip-flops, JK flip-flops, T flip-flops, and SR flip-flops. D flip-flops have a single data input and a clock input and can store one bit of information. JK flip-flops have two inputs, J and K, and can store one bit of information. T flip-flops have a single input and can toggle between two states based on the clock signal. SR flip-flops have two inputs, S and R, and can store one bit of information.

Latches and flip-flops are used in various applications, including digital signal processing, memory systems, and control circuits. They are essential components of digital systems and can be found in many electronic devices, such as computers, mobile phones, and digital cameras.
