Abstract
A demultiplexer has a main circuit section obtained by connecting a plurality of 1:2 demultiplexers, each for distributing a time-divisionally multiplexed signal into tow parts, to form a tree-like arrangement, and a clock frequency divider for frequency-dividing an input clock signal to generate frequency-divided signals to be supplied to the 1:2 demultiplexers of the respective stages of the tree-like arrangement. The demultiplexer has a plurality of inverting circuits for arbitrarily inverting the frequency-divided clock signals supplied from the clock frequency divider to the respective stages of the main circuit section in units of stages.
