Die for a printhead

A method for forming a die for a printhead, comprising:

• etching a plurality of fluid feed holes in a line down a substrate;
• depositing a plurality of layers on the substrate to form:
• a plurality of fluidic actuator arrays, proximate to the plurality of fluid feed holes;
• a plurality of address lines, proximate to a plurality of logic circuits in a low-voltage region disposed on one side of the plurality of fluid feed holes;
• an address decoder circuit that couples to at least a portion of the plurality of address lines to select a fluidic actuator in a fluidic actuator array for firing, wherein the address decoder circuit is customized to select a different address for each fluidic actuator in the fluidic actuator array;
• and
• a logic circuit in the plurality of logic circuits that triggers a driver circuit located in a high-voltage region on an opposite side of the plurality of fluid feed holes based, at least in part, on a bit value for the fluidic actuator array, the fluidic actuator selected by the address decoder circuit, and a firing signal.
