NAND Gate: It is the combination of two basic logic gates, the AND gate and the NOT gate connected in series. The NAND gate and NOR gate can be called the universal gates
Now let us look at the logic symbol and the logic expression of the NAND gate circuit. The logic symbol of a NAND gate is shown below. A NAND gate consists of two basic gates AND and NOT. An AND gate is connected to NOT gate in series. The bubble at the output of the NAND gate ...
The NAND gate has an output that is normally at logic high and only goes to logic low when all of its inputs are at logic high. The Logic NAND Gate is the reverse or complementary design of the AND gate. Through this article on NAND gates, you will learn about the symbol, truth tab...

While an AND gate outputs a logical “1” only if both inputs are logical “1,” a NAND gate outputs a logical “0” for this same combination of inputs. The symbol and truth table for a NAND gate is shown in Figure 1. The Boolean expression for a NAND gate with two inputs (A...
TheAND gateis so named because, if 0 is called "false" and 1 is called "true," the gate acts in the same way as the logical "and" operator. The following illustration and table show the circuit symbol and logic combinations for an AND gate. (In the symbol, the input terminals are ...
XOR gate symbol (a) XOR-A From the above behavior specification, we can obtain a logic relationship of the output with the inputs as follows: Out=In1⋅In2¯+In1¯⋅In2 A direct implementation of this logic relationship requires 22 transistors as shown in Figure 11. Because logic ...
While an AND gate outputs a logical “1” only if both inputs are logical “1,” a NAND gate outputs a logical “0” for this same combination of inputs. The symbol and truth table for a NAND gate is shown in Figure 1. The Boolean expression for a NAND gate with two inputs (A...
diode cluster marked “Q1” is actually formed like a transistor, even though it isn’t used in any amplifying capacity. Unfortunately, a simple NPN transistor structure is inadequate to simulate thethreePN junctionsnecessary in this diode network, so a different transistor (and symbol) is needed...
