Claim:
1. A semiconductor device for a liquid discharge head, the device comprising: a plurality of first transistors each including a first terminal, a second terminal, and a control terminal, and configured to receive a first voltage at the first terminal; a plurality of second transistors each including a first terminal, a second terminal, and a control terminal, and configured to receive a second voltage at the first terminal; a plurality of discharge elements configured to discharge a liquid, each discharge element being connected between the second terminal of one of the plurality of first transistors and the second terminal of one of the plurality of second transistors; a first control circuit configured to supply a first control signal for controlling a conductive state of the plurality of first transistors to the control terminals of the plurality of first transistors via a common signal line connected to the plurality of first transistors; and a stabilization circuit configured to stabilize a voltage of at least one of the second terminal of the first transistor or the control terminal of the first transistor.
