Abstract
An integrated circuit to drive a plurality of fluid actuation devices includes a plurality of contact pads, a plurality of pulldown devices, and control logic. The plurality of contact pads include a first contact pad and a second contact pad. Each of the pulldown devices is electrically coupled to a corresponding contact pad. The control logic enables at least a portion of the pulldown devices in response to both a logic low signal on the first contact pad and a logic low signal on the second contact pad.
