Abstract:
A semiconductor integrated circuit device, having at least one selector, the selector in the integrated circuit comprising:first and second PMOS transistors; first and second NMOS transistors; first to fourth input terminals; and a first node; wherein a source-drain path of the first PMOS transistor is connected between the first input terminal and the first node; a source-drain path of the first NMOS transistor is connected between the first input terminal and the first node; a source-drain path of the second PMOS transistor is connected between the second input terminal and the first node; a source-drain path of the second NMOS transistor is connected between the second input terminal and the first node; a gate terminal of the first PMOS transistor is controlled by a first signal applied to the third input terminal; a gate terminal of the second NMOS transistor is controlled by the first signal applied to the third input terminal; a gate terminal of the second PMOS transistor is controlled by a second signal applied to the fourth input terminal; a gate terminal of the first NMOS transistor is controlled by the second signal applied to the fourth input terminal; the first signal and the second signal are complementary signals; the drain of the first PMOS transistor and the drain of the second PMOS transistor are arranged to share their diffusion layers so that they are connected to each other; and the drain of the first NMOS transistor and the drain of the second NMOS transistor are arranged to share their diffusion layers so that they are connected to each other; wherein common portions of the source of the first PMOS transistor and the drains of the first and second NMOS transistors are arranged in line in a direction intersecting a direction in which a power supply line extends; and common portions of the source of the second NMOS transistor and the drains of the first and second PMOS transistors are arranged in line in a direction intersecting a direction in which the power supply line extends.
