An output terminal circuit is disclosed. The circuit comprises a supply power supply source; a ground power supply source; a first inverting gate for inverting an input signal; a first PMOS transistor having a source connected to the supply power supply source and a gate connected to a gate of the first inverting gate; a second inverting gate for inverting the output signal from the output signal from the first inverting gate; a first NMOS transistor having a source connected to the ground power supply source and a gate connected to the first inverting gate; a second NMOS transistor having a drain connected to the drain of the first PMOS transistor and a gate connected to the output of the second inverting gate; a second PMOS transistor having a source connected to the source of the second NMOS transistor, a gate connected to the gate of the second inverting gate and a drain connected to the drain of the first NMOS transistor; a third inverting gate for inverting the source signal from the second PMOS transistor; a third PMOS transistor having a source connected to the first PMOS transistor and a gate connected to the output of the third inverting gate; and a third NMOS transistor having a drain connected to the third PMOS transistor, a gate connected to the output of the third inverting gate and a source connected to the drain of the first NMOS transistor. Thereby, a stable output signal can be obtained.
