An address decoder is a combinational logic circuit that takes an n-bit address and selects one of 2^n possible outputs based on the value of the input address. It is commonly used in digital systems to enable or disable a specific memory location, register, or peripheral device based on the address. The address decoder essentially acts as a translator between the address bus and the control signals that are used to select a particular device or memory location. The most common type of address decoder is the binary decoder, which uses binary logic to decode the address inputs. Other types of address decoders include the octal decoder and the hexadecimal decoder, which are used for decoding addresses in base-8 and base-16 formats, respectively.
