Latches

Latches are a type of integrated circuit (IC) that is used to store a binary value. They are typically made up of a set of gates and flip-flops that are interconnected in a particular way, and that can be used to hold a digital value in a stable state. Latches are commonly used in digital circuits as temporary storage elements, where they can hold a value until it is needed by other parts of the circuit. They are often used in conjunction with other logic gates, such as AND, OR, and NOT, to implement more complex logical operations. Latches are typically classified by the number of bits they can store, and by the type of logic they use, such as TTL (transistor-transistor logic) or CMOS (complementary metal-oxide-semiconductor).
