A decoding and level shifting circuit comprises first and second n-channel transistors each having a source connected to a high negative potential, a gate and a drain of the first n-channel transistor being connected to a drain and a gate of the second n-channel transistor, respectively. A first group of p-channel transistors are connected in parallel between the drain of the first n-channel transistor and a ground level, and gates of the first group of p-channel transistors are connected to receive a first group of signals, respectively. A second group of p-channel transistors are connected in series between the drain of the second n-channel transistor and the ground level, and gates of the second group of p-channel transistors are connected to respectively receive a second group of signals complementary to the first group of signals. The drain of the second n-channel transistor gives an output.
