An address decoder is a digital circuit that takes an address as input and selects one or more output lines based on that address. It is commonly used in digital systems such as microprocessors, memory systems, and input/output devices. The purpose of an address decoder is to enable specific devices or circuits to respond to specific addresses. For example, in a memory system, the address decoder selects the specific memory location based on the address provided by the microprocessor. In input/output devices, the address decoder selects the specific device based on the address provided by the microprocessor. The address decoder is a crucial component in digital systems as it ensures that the correct device or circuit is accessed based on the address provided.
