Abstract
An output circuit for an integrated circuit device in which first and second power wirings are connected to a high-potential power terminal, third and fourth power wirings are connected to a low-potential power terminal, and a plurality of inverters are responsive, respectively, to a plurality of bit data signals, each being formed of P-channel and N-channel MOS transistors having drains thereof connected together, a junction of which forms an output terminal. First to fourth auxiliary transistors are provided for each of the inverters, which are connected, respectively, between the first power wiring and the source of the P-channel MOS transistor, between the second power wiring and the source of the P-channel MOS transistor, between the third power wiring and the source of the N-channel MOS transistor, and between the fourth power wiring and the source of the N-channel MOS transistor. First and second circuits are provided for each inverter and operable in response to one of the bit signals corresponding to each inverter to control the transistors ON and OFF states.
