Abstract
A semiconductor device for a liquid discharge head is provided. The device includes first transistors configured to receive a first voltage at a first terminal and second transistors configured to receive a second voltage at a first terminal. The device further includes discharge elements configured to discharge a liquid. Each discharge element is connected between a second terminal of a first transistor and a second terminal of a second transistor. A first control circuit is configured to supply a first control signal for controlling a conductive state of the first transistors via a common signal. A stabilization circuit is 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.
