    摘要: A liquid discharge head substrate includes an external terminal, a diode, a first conductive layer, a second conductive layer, and a third conductive layer. The external terminal is configured to connect to an external. The first conductive layer is connected to the external terminal for causing an input current to flow from the external terminal, and the diode includes an anode and a cathode. The second conductive layer is connected to the first conductive layer and one electrode of the anode and cathode, and causes a surge current generated when a surge voltage is applied from the external terminal, to flow from the first conductive layer to the one electrode. The third conductive layer is connected to the other electrode of the anode and the cathode and passes the surge current flowing from the one electrode to the other electrode. The first conductive layer includes a part laminating with the second conductive layer sandwiching an insulation layer, and does not include a part laminating with the third conductive layer.

    摘要: This invention relates to a printhead element substrate having a plurality of electrothermal transducers and a plurality of switching elements which drive the plurality of electrothermal transducers. The element substrate has a level converter which is shared by adjacent electrothermal transducers and steps up an input driving signal, and a switch circuit which supplies the driving signal output from the level converter to one of the adjacent electrothermal transducers. The switch circuit switches the supply destination of the driving signal in accordance with an external input selection signal.
