PROBLEM TO BE SOLVED: To provide a semiconductor device having small amplitude interface by which high speed and stable operation is performed. SOLUTION: In an input circuit, an output of a first differential comparator comparing a signal, to which reference signals VTRb and VTRt are divided internally effectively with a desired first ratio, with an input signal D and an output of a second differential comparator comparing a signal, to which reference signals VTRb and VTRt are divided internally effectively with a desired second ratio, with an input signal D are switched by a switching logic circuit STL. Effective signal quantity at the time of transition can be enlarged, securing voltage margin at the time of non-transition of the input signal D.
