Abstract
A liquid discharge head control circuit includes a first wiring for propagating a first reference voltage signal to be supplied to a driving signal selection circuit, a second wiring for propagating a second reference voltage signal to be supplied to a restoration circuit, a third wiring for propagating the second reference voltage signal to be supplied to the restoration circuit, a fourth wiring for propagating one signal of a pair of first differential signals, and a fifth wiring for propagating the other signal of a pair of first differential signals. The fourth wiring and the fifth wiring are arranged side by side. The fourth wiring and the second wiring are located to be adjacent to each other, the fifth wiring and the third wiring are located to be adjacent to each other, and the fourth wiring and the fifth wiring are located between the second wiring and the third wiring.
