| Zusammenfassung: | To reduce an effect of crosstalk noise by a method that does not affect miniaturization and improvement in integration.SOLUTION: The semiconductor integrated circuit includes: two or more sequential circuits; and a branch circuit for branching a signal from the sequential circuit into at least two or more signals. The branch circuit is arranged near the sequential circuit. The branch circuit has at least one of outputs of the branch circuit connected to the ground potential when a selection signal is connected to the ground potential and a signal connected to the ground potential and the selection signal are arranged adjacent to both sides of a signal input to the sequential circuit.SELECTED DRAWING: Figure 1
