Output circuit device for clock signal distribution

摘要

An output circuit device has an output circuit connected between a first power supply line and a second power supply line via a control circuit having at least one isolating transistor. A control voltage held at a constant level is applied to a control electrode of the isolating transistor, and the control voltage is a voltage at a level that works to attenuate high-frequency components contained in a voltage supplied from the first or the second power supply line.
