In order to reduce crosstalk caused between control signal wires 14, 15, 16 in a semiconductor apparatus without increasing the size of the semiconductor apparatus, a noise guard circuit 13 is provided at the opposite end of the control signal wire 14, 15, 16 to the driver circuit 12. The noise guard circuit 13 operates in such a way as to increase the impedance between the relevant control signal wire 15 and a fixed potential when the logic of the relevant control signal wire 15 is logical positive for driving the element 10, and to decrease the impedance between the relevant control signal wire 15 and a fixed potential when the logic of the relevant control signal wire 15 is logical negative for driving the element 10.
