PURPOSE:To facilitate the design and to secure the reliability of an LSI by devising the synchronizing type digital circuit such that the timing is made adjustable. CONSTITUTION:Plural delay elements 2 connected in series and plural fuse elements 3 connected in parallel with the delay elements 2 are interposed between an input terminal 10 of a circuit 1 operated based on a signal inputted in a required timing and a clock signal terminal 4, and the fuse elements 3 are selectively blown out after the manufacture of the LSI to change a delay of a timing signal inputted from the terminal 4 thereby adjusting the operating timing of the entire circuit. |
