Abstract
A Schmitt circuit for a semiconductor integrated circuit has resistances of predetermined resistors of the Schmitt circuit respectively selected from a plurality of resistances so as to obtain desired threshold voltages by selecting electrodes to which wiring is connected when producing the semiconductor integrated circuit according to the master slice method. Thus the Schmitt circuits have different threshold voltages depending on the selection of the electrodes to which the wiring is connected.
