摘要:
A die for a printhead is described herein. The die includes a number of fluid feed holes disposed in a line parallel to a longitudinal axis of the die, wherein the fluid feed holes are formed through a substrate of the die. A number of fluidic actuators are proximate to the fluid feed holes to eject fluid received from the plurality of fluid feed holes. The die includes logic circuitry to operate the fluidic actuators, wherein the logic circuitry is disposed on a first side of the plurality of fluid feed holes. Power circuitry to power the plurality of fluidic actuators is disposed on an opposite side of the fluid feed holes from the logic circuitry. Activation traces are disposed between each of the fluid feed holes to couple the logic circuitry to the power circuitry.
