Semiconductor integrated circuit

摘要

There is disclosed a semiconductor integrated circuit comprising pass transistor circuits (PT3, PT4) for producing logically complementary signals. The output of the pass transistor circuit (PT3) is connected to the base electrode of an NPN bipolar transistor (BN1), and the output of the pass transistor circuit (PT4) is connected to the gate electrode of an NMOS transistor (MN9). PMOS transistors (MP15, MP16) are connected between the outputs of the pass transistor circuits (PT3, PT4) and a first potential (VDD). The gate electrodes of the PMOS transistors (MP15, MP16) are connected to the outputs of the pass transistor circuits (PT3, PT4). The bipolar transistor (BN1) having a large driving force charges and discharges a load capacity (CL1) connected to an output terminal in response to the output signal of the pass transistor circuit (PT3). This provides for a logic circuit which operates at high speeds in the semiconductor integrated circuit.
