Special Logic ICsThere are many types of special logic ICs, each designed to perform a specific function in a digital circuit. Some examples of special logic ICs include multiplexers, demultiplexers, decoders, encoders, and shift registers. Multiplexers and demultiplexers are used to select and route digital signals, while decoders and encoders are used to convert between different code formats. Shift registers are used to store and shift digital data. These and other special logic ICs are commonly used in digital circuits to perform a variety of functions.
