    Abstract: Examples include a fluidic die. The fluidic die comprises an array of field effect transistors. Connecting members electrically connect at least some of the field effect transistors of the array of field effect transistors, and the field effect transistors of the array are arranged into respective sets of field effect transistors. The fluidic die further comprises a first fluid actuator connected to a first set of field effect transistors having a first number of field effect transistors. The die includes a second fluid actuator connected to a second respective set of field effect transistors having a second number of field effect transistors that is different than the first number of field effect transistors.

    Abstract: Examples include a fluid ejection die having a die length and a die width. The fluid ejection die may include a plurality of nozzles arranged along the die length and a die width. The plurality of nozzles is arranged such that at least one pair of neighboring nozzles are positioned at different die width positions along the width of the fluid ejection die. The example fluid ejection die further includes a plurality of ejection chambers including a respective ejection chamber fluidically coupled to each respective nozzle. The fluid ejection die further includes an array of fluid feed holes. The array of fluid feed holes includes a first respective fluid feed hole fluidically coupled to each respective ejection chamber, and the array of fluid feed holes includes a second respective fluid feed hole fluidically coupled to each respective ejection chamber.

    Abstract: The fluid ejection device includes a plurality of nozzles and a plurality of ejection chambers that includes a respective ejection chamber fluidically coupled to a respective nozzle. A plurality of inlet passages are fluidically coupled to the ejection chambers and input fluid to the ejection chambers at a first pressure. A plurality of outlet passages are fluidically coupled to the ejection chambers and output fluid from the ejection chambers at a second pressure that is less than the first pressure. Fluid circulates through the ejection chambers based on the pressure difference between the first and second pressure. The fluid ejection device also includes at least one fluid actuator fluidically coupled to at least one ejection chamber to pump fluid through the at least one ejection chamber.
