We’ve all heard of the dangers of static electricity when dealing with electronics, and we all take the proper precautions when working with static-sensitive components — don’t we? But as much as we ...

Who would have thought that a circuit comprising only two 2-input NAND gates could be so complicated (or, should we say, “interesting”)? Up to this point (click here to see my earlier columns), the ...

Now, the thing to remember is that we are using a CD4512 chip, whose truth table is shown below. The important thing to note here is that, in addition to the three multiplexer select controls, A, B, ...
