Abstract:
A die for a printhead is described herein. The die includes fluid feed holes disposed in a line parallel to a longitudinal axis of the die. The fluid feed holes are formed through a substrate of the die. Fluidic actuators are proximate to the fluid feed holes, to eject fluid received from the fluid feed holes. Field-effect transistors are parallel to the fluid feed holes. Each fluidic actuator is powered by an associated field effect transistor. Logic circuitry to actuate the field-effect transistors is disposed on an opposite side of the fluid feed holes from the field-effect transistors. Traces, disposed between the fluid feed holes, electrically couple the logic circuitry to the field-effect transistors. The die has a repeating structure including one fluid feed hole, two fluidic actuators, and two field-effect transistors placed at an interval of two times a dot pitch in a line along the die.
