We report on the experimental demonstration of a magnetic domain wall logic device - a 2bit demultiplexer or a biplexer - that sorts vortex domain walls, created in the input branch, into one of the two output branches of a Y-shaped magnetic nanostructure based on their chiralities. We show that this sorting behavior is insensitive to the angle that the two output branches of the Y-shaped nanostructure subtend with each other, which we attribute to a topological protection stemming from the constituent fractional topological defects of the domain wall.
