Abstract
A demultiplexer circuit which can simultaneously demultiplex plural pieces of input data while minimizing the circuit scale. The demultiplexer circuit includes an input line identification information addition circuitfor giving input line identification information to input data which have data identification information and are inputted through plural input lines, respectively; a multiplexerfor outputting the input data which have been given the input line identification information, respectively, by the input line identification information addition circuitthrough one common line; a filterfor filtering the data outputted from the multiplexeron the basis of the input line identification information and the data identification information at one time; and a filter tablethat contains filtering conditions which are used in the filter
