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.
