1-26. (canceled)
An integrated circuit to drive a plurality of fluid actuation devices, the integrated circuit comprising:
- an interface;
- a digital circuit to output a digital signal to the interface;
- an analog circuit to output an analog signal to the interface;
- and
- control logic to activate the digital circuit or the analog circuit.
An integrated circuit to drive a plurality of fluid actuation devices, the integrated circuit comprising:
- an interface;
- an analog circuit to output an analog signal to the interface;
- and
- a timer to override the analog signal on the interface from the analog circuit in response to the timer elapsing.
An integrated circuit to drive a plurality of fluid actuation devices, the integrated circuit comprising:
- a data interface;
- an output interface;
- and
- a shift register to shift nozzle data into the integrated circuit through the data interface and shift the nozzle data out of the integrated circuit through the output interface.
