ABSTRACT:
A nozzle assembly for an inkjet printhead is disclosed. The nozzle assembly includes an inkjet nozzle having an actuator for ejecting an ink droplet from the inkjet nozzle when a resistive element of the actuator is heated by an electrical current, a shift register comprising a plurality of successive registers, the shift register receives input data in a first register, and shifts the input data to successive registers upon receipt of a shift signal, a transfer register for latching data in one of the registers of the shift register; a control gate for outputting a control pulse in response to data in the transfer register, and a drive transistor for providing an energy pulse to the resistive element of the actuator upon receipt of the control pulse. Each energy pulse has a pulse voltage of less than 10 Volt.
