The switch diagrams help clarify these rules ... The order of precedence is less well defined for logic circuits, like XOR or NAND, which are derived from the three basic circuits.

The logic only uses NAND gates ... If you try the circuit out, you can see the output will change, and flipping the switch won’t matter. If you break one of the inputs and ground it, for ...

Here’s a blast from the past as we reprint our news from NYC’s 1961 IRE show—the first integrated logic circuits in TO-5 and TO-18 cans are being announced. March 29, 1961 - LOGICAL ...
