Abstract
An integrated circuit to drive a plurality of fluid actuation devices includes an interface, a digital circuit, an analog circuit, and control logic. The digital circuit outputs a digital signal to the interface. The analog circuit outputs an analog signal to the interface. The control logic activates the digital circuit or the analog circuit.
Claims13
An integrated circuit for a fluid ejection device, the integrated circuit comprising:
- an interface including a pad, the interface to selectively couple the pad with a memory cell and to selectively couple the pad with a thermal sensor;
- 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.
