1. BASIC LOGIC GATES

2. In studying digital in integrated circuits, one must start with the simples group of circuits, the SSIs or Small Scale Integrated Circuits. Since this devices contain only a maximum of 10 transistorized components inside, these chips normally contain a function used in Boolean Algebra. Switching functions using Boolean Algebra is the simplest operation used in digital circuits, since it only involves a zero (0) and a one (1), much like the false (if zero) and true (if one) signals of Boolean algebra.
