SCHMITT CIRCUIT OF SEMICONDUCTOR IC

摘要

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