BIMOS logic circuit directly controllable by a CMOS block formed on same IC chip

摘要

A single chip IC includes a bipolar logic, a complementary metal-oxide semiconductor (CMOS) logic, and a level translator which interfaces the bipolar logic with the CMOS logic. The single chip IC comprises a MOS transistor logic, provided in the bipolar logic, for receiving a control signal which controls an operation of the bipolar logic. The control signal issues from the CMOS logic and bypasses the level translator and is applied to the MOS transistor logic.
