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 is also included. 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 latches data in one of the registers of the shift register. A control gate outputs a control pulse in response to data in the transfer register. A drive transistor provides an energy pulse to the resistive element of the actuator upon receipt of the control pulse.
