Output circuit including current mirror circuits

Abstract

The invention provides an output circuit in a semiconductor integrated circuit which comprises an input terminal for receiving input signals controlling output circuits, an output terminal for delivering output signals driving a load device being connected to the output terminal, high and low voltage supply lines for supplying high and low voltage driving the output circuit, a first current mirror circuit on its output stage including a single transistor being connected between the high voltage supply line and the output terminal, a second current mirror circuit on its output stage including a single transistor being connected between the low voltage supply line and the output terminal, a first logic circuit being connected between the input terminal and the first current mirror circuit for receiving input signals from the input terminal for a subsequent controlling of the first current mirror circuit, and a second logic circuit being connected between the input terminal and the second current mirror circuit for receiving input signals from the input terminal for a subsequent controlling of the second current mirror circuit.
