Four.
two nand gates
by multiplying two NAND gates
The 7400, and its variations, is a quad two input NAND gate.
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
There are two universal gates called NAND and NOR
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
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
and gates or gates nor gates nand gates are the electronics logic gates.
