Fluid ejection device with data signal latch circuitry
Abstract:
A fluid ejection device includes a plurality of firing cells and a fire line adapted to conduct an energy signal including energy pulses. Each firing cell in the plurality of firing cells includes a firing resistor, a drive switch, a first data switch, and a second data switch. The drive switch is configured to enable the firing resistor to respond to the energy signal. The first data switch is configured to receive data signals that represent an image and to latch the data signals to provide latched data signals. The second data switch is configured to receive the latched data signals and control the drive switch to enable the firing resistor to respond to the energy signal and heat fluid to be ejected based on the latched data signals.
