Abstract
A device includes a first element substrate and a second element substrate for driving a driving element; a first signal input unit connected to an input terminal of the first element substrate; a second signal input unit connected to an input terminal of the second element substrate; and a signal output unit. Each of the first and second element substrates includes a driving element, a first signal generation unit configured to output a first signal, a second signal generation unit configured to output a second signal, an input terminal, an output terminal, and a selection unit configured to receive a signal from the first and the second signal generation units, select one of a state of the first signal, a state of the second signal, and a high-impedance state on the basis of the selection signal input from the input terminal, and output the state to the output terminal.
