Abstract
An additional MOS transistor receiving at its control electrode a signal complementary to that applied to control electrodes of MOS transistors is provided between a power supply node and a control electrode line formed by resistors having a significant resistance and interconnecting respective control electrodes of MOS transistors which are connected in parallel and each of which is connected between output signal line and power supply node. When MOS transistors are rendered non-conductive, the additional MOS transistor is rendered conductive. As a result, internal nodes are driven by an inverter and the additional MOS transistor to a power supply voltage, thereby turning off MOS transistors at the same timing. Consequently, through current in a semiconductor output circuit can be suppressed and an output signal has no ringing.
