ABSTRACT:
An output circuit device according to the present invention comprises first circuit means (1) having a first type MOS transistor and a second type MOS transistor connected in parallel to each other, second circuit means (3) having at least a first type MOS transistor and a second type MOS transistor connected in parallel to each other, and a load capacitor means (13) connected between the output terminal and the ground potential for charging and discharging electric charge of an output signal.
The source of said first type MOS transistor is connected to a first power supply and the source of said second type MOS transistor being connected to a second power supply.
The second circuit means is connected between the output of said first circuit means and an output terminal. The source of the first type MOS transistor in the second circuit means is connected to the first power supply. The source of the second type MOS transistor is connected to the second power supply. The first and second type MOS transistors have a first threshold voltage level.
Thereby, undershoot and overshoot phenomena are suppressed when the output potential of the first and second type MOS transistors in the second circuit means reaches the threshold voltage level.
