Abstract:
A semiconductor integrated circuit device comprising:a constant current source directly connected to a first power supply via a power terminal; first and second current switches connected to an end of said constant current source in parallel with each other, and configured to output first and second outputs complementarily on the basis of first and second control signals that are complementarily applied from a driving means; a first terminal electrically connected to a first end of said first current switch opposite from the end thereof connected to said constant current source, and configured to output said first output to the outside as the output of said semiconductor integrated circuit; a second terminal electrically connected to a second end of said second current switch opposite from the end thereof connected to said constant current source, and configured to output said second output to the outside as the output of said semiconductor integrated circuit; first resistive elements, a first of which is connected in a first path between said first end of said first current switch and said first terminal and a second of which is connected in a second path between said second end of said second current switch and said second terminal; and a resistive element connected in a third path between said first terminal and a second power supply; and wherein said second terminal is directly connected to said second power supply.
