Title: Semiconductor integrated circuit
Inventor: TANAKA HIRONORI
IPC: H03K19/0952
Filed: 1990-11-21
Abstract: PURPOSE:To suppress the potential fluctuation of a common source and to set the falling time of an output signal at a high speed by connecting a capacitance element between the common source for which the source electrode of a switch FET of a current switching part is connected in common, and a constant-voltage power source. CONSTITUTION:To a transistor F201, a current I2 from a transistor FL1 and a discharging current IL from a load capacitance connected to a terminal (a) flow, and a part of I2 and IL is used as the charging current of a capacitor CC. When the value of CC is set in advance to the sufficient large value of about several pFs, a potential difference across CC is hardly varied in a short time when outputs of (a) and (-a) are switched. CC can absorb a current exceeding a current I3 flowing through a transistor F202, and simultaneously, keeps the potential of C constant, and works so that the current exceeding I3 can be allowed to flow to F201.
