摘要:
A compound semiconductor integrated circuit is adapted to provide an interface with respect to an internal circuit which is driven by first and second power source voltages and operates responsive to a logic signal having a predetermined logic level which is different from an emitter-coupled logic level. The compound semiconductor integrated circuit includes an input circuit part which is driven by the first and third power source voltages and receives an input logic signal having the emitter-coupled logic level, and an output circuit part which is driven by the first and second power source voltages and converts an output signal of the input circuit part into a signal having the predetermined logic level. The second power source voltage is lower than the first power source voltage. The third power source voltage is different from the second power source voltage and is lower than the first power source voltage. The output circuit part supplies an output thereof to the internal circuit.
