The NAND gate has two or more inputs, and one output. This output is the complement of the AND of all the bits and will only be 0 if all the inputs are 1.A NOT gate on the other hand has only 1 input, and the output is the complement of this input.So to make a NAND gate into a NOT gate, we should tie (short, connect to same value) all the inputs of the NAND gate. At the output we would have the complement of the signal given at the tied inputs.This way we have a NOT gate from a NAND gate.
A NAND gate.
That title of "Universal Gate" is reserved for NAND gates because you can build all possible logic using only NAND logic . You can build even other basic logic like AND, OR and NOT using NAND.
There are two forms of the NAND gate. Inverted input: Ouput = not Input1 and not Input2 and not Input3 ... Inverted output: Output = not (Input1 and Input2 and Input3 ...)
NAND gates are universal gates and can be used to construct any of the logic gates (AND, OR, NOT, NOR, XOR, XNOR). The easiest way to figure this out is to use basic Boolean Laws. For instance, to create a NOT gate (A'), tie one of the NAND gate's input to logic high: (A+1)' = A'. To create an AND gate (AxB), use two NANDs in series, with the second one configured as an inverter: (AxB) = ((AxB)')'
A: A AND gate becomes a NAND when the output is merely negated or inverted
the not gate applied to and gate is nand gate
when the two inputs are shorted, a NAND gate acts like a NOT gate. hence AND = NAND + NOT For OR gate, inverse both the inputs before connecting them to a NAND gate. So three NAND gates would be needed.
A nand gate can be made from an and gate by introducing an inverter at the output of the gate.
74ls00 is the ic no. Of nand gate
nand gate
Connect the two inputs of the NAND gate together.
When the two input terminals of a NAND gate are short circuited, it acts as a NOT gate.
pass the inputs through an nand gate and again pass them through inverter,which is again formed by an nand gate

The TTL Nand gate is usually used in the design of various electric circuits.
