An LS part, for example, didn’t need the extra resistor ... However, you could use other gates, including the other XOR gates in the package to realize a fast delay. Frequency doublers are ...

As an example, let’s consider the AND gate (the others are OR, NOT, NAND, NOR, XOR and XNOR). Electronic gates operate on two nominal voltages, normally 0 V and 5 V, representing the logic 0 ...
