Those pins should not be connected to any of your circuit connections (apart from possibly [[power rail]]s). |
| − | + | IC chips are mostly mass produced in a limited array of [[integrated circuit package types|packages]]. Most designers are thus restricted to one of those pre-defined packages. Sometimes the device that's designed does not utilize all the pins for various reasons. Some manufacturers may also designate some pins for their internal use only (e.g. calibration or testing). When that happens, those pins gets labeled "NC" or "Not Connected". | |
