    In mathematics, the number or quantity obtained by multiplying two (or more) numbers together is called the product. In Boolean Algebra the AND function is the equivalent of multiplication and so its output state represents the product of its inputs. The AND function is represented in Boolean Algebra by a single “dot” (.) so for a two input AND gat...

    In mathematics, the number or quantity obtained by adding two (or more) numbers together is called the sum. In Boolean Algebra the OR function is the equivalent of addition so its output state represents the addition of its inputs. In Boolean Algebra the OR function is represented by a “plus” sign (+) so for a two input OR gate the Boolean equation...

    The NOTgate, which is also known as an “inverter” is given a symbol whose shape is that of a triangle pointing to the right with a circle at its end. This circle is known as an “inversion bubble”. The NOT function is not a decision making logic gate like the AND, or ORgates, but instead is used to invert or complement a digital signal. In other wor...

    One of the main disdvantages of using the complete sets of AND, OR and NOT gates is that to produce any equivalent logic gate or function we require two (or more) different types of logic gate, AND and NOT, or OR and NOT, or all three as shown above. However, we can realise all of the other Boolean functions and gates by using just one single type ...

    The 7400 (or the 74LS00 or 74HC00) quad 2-input NAND TTL chip has four individual NAND gates within a single IC package. Thus we can use a single 7400 TTL chip to produce all the Boolean functions from a NOT gate to a NORgate as shown.

    The 7402 (or the 74LS02 or 74HC02) quad 2-input NOR TTL chip has four individual NOR gates within a single IC package. Thus like the previous 7400 NAND IC we can use a single 7402 TTL chip to produce all the Boolean functions from a single NOT gate to a NANDgate as shown.
