ABSTRACT:
A semiconductor integrated circuit device has a plurality of emitter-coupled logic (ECL) gates. Separate power source wiring lines are provided for current switch circuits and emitter follower output circuits for the gates. The separate sets of power source wiring lines are respectively coupled to the corresponding external terminals of the semiconductor integrated circuit device. The power source wiring lines for each set are arranged adjacent one another on a semiconductor chip in order that they may be short circuited or kept separated depending upon the package structure of the semiconductor integrated circuit device.
