Alwayslatches

Always latches are a type of electrical switch used in electronic circuits. They are also known as keepers or contacts. Always latches are used in a wide range of applications, including digital logic circuits, timing circuits, and state machines.

A latch typically consists of two or more electronic switches that are in contact with each other.

Always latches are used to implement memory and storage functions in digital electronics. There are two main
