Abstract
An output circuit capable of high-speed operation, large current output, and low power consumption. The output circuit includes an input transistor for receiving an input signal, a pair of output transistors for supplying an output signal to the load at a desired current level, a resistor network provided between the output transistors, a level shift circuit for shifting a bias voltage of the input transistor to determine a bias voltage of the output transistors thereby defining bias current in the output transistors, and an inverse current circuit for supplying a current to the resistor network which is opposite to the current supplied from the output transistor when the output current from one of the output transistors to the load exceeds the predetermined value.
