Offers a circuit that reduces or removes crosstalk with a method that does not exert influence on improvements in miniaturization and the degree of integration. The crosstalk prevention circuit, between at least two signal lines that are formed almost in parallel, for example, a master clock line and a slave clock line 11, 12, makes a third signal line 13 that applies a signal when a signal is not applied to at least one of these two signal lines, for example, a test signal, and becomes in a grounded condition when a signal is applied to the above-mentioned two signal lines. Preferably, a driver circuit is connected to the third signal line, and the ratio of the current drive capabilities of the N channel transistor and the P channel transistor of the output transistors of said driver circuit is made about 2:1.
