two nand gates
by multiplying two NAND gates
The 7400, and its variations, is a quad two input NAND gate.
The 7400 series is a family of integrated circuits (ICs) that contain multiple logic gates. The name "7400" refers to the first IC in the series, which is a quad 2-input NAND gate. Each subsequent IC in the 7400 series follows a similar naming convention based on the logic gates it contains.
The 7400, and its variations, is a quad two input NAND gate.
Seven gates, they are: not, and, or, nor, nand, xor, xnor.
And, or, xor, xnor, nand, nor, not
Nand, nor, and, or, xor, nxor, not, true.
Nand and nor gates are called universal gates .they called so as since any logic function can be done with nand and nor gates
There are 2 types of universal gates in physics: the NAND gate (combinations of NAND gates can produce any logic function) and the NOR gate (combinations of NOR gates can also produce any logic function). These gates are considered universal because they can be used to implement any logical function.
A&B = ((A&B)')' So two, it would go a - | ==NAND--=NAND-- b - | By using two NAND gates back-to-back, you can create a normal AND gate.
it is made bu use ing nand gates logic
