Texas Instruments’ 5400 and 7400 TTL quad 2-input NAND gate has been in continuous production since 1964 and is the progenitor of what is probably the most numerous breed of integrated circuits, ...

As an example, let’s consider the AND gate (the others are OR, NOT, NAND, NOR, XOR and XNOR ... all other gates can be implemented. The three input, diode-only AND gate is shown in the ...
