Abstract
print component includes a data pad, a clock pad to receive an intermittent clock signal, and an actuator group corresponding to the data pad. The actuator group includes a plurality of configuration functions for configuring an operational setup of a corresponding actuator group, an array of fluid actuators, and an array of memory elements including a first portion corresponding to the plurality of configuration functions and a second portion corresponding to the array of fluid actuators. Each time the intermittent clock signal is present on the clock pad, the array of memory elements to serially load a segment of data bits from the data pad, including loading a first portion of data bits into the first portion of memory elements, and loading a second portion of data bits into the second portion of memory elements.
