Logic type signal switch, multiplexer, and encoder ICs are used for routing and selection of electrical signals used to represent data in digital format. They differ from similar products designed for use with analog signals in that they are designed to preserve information represented as one of two electrical states, rather than as an infinitely variable quantity within two outer limits.
