Nand Gate Circuit. The circuit of full adder using only nand gates is shown below. If we connect the output of and gate to the input of a not gate the gate so obtained is known as nand gate.
Basically we use the first gate of the 4011 as the gate where we have our inputs. This simplifies the expression such that only one standard gate is used throughout. Full adder using nand gates full adder is a simple 1 bit adder.
The nand gate is essential because different types of a boolean function are implemented by using it.
The circuit schematic for an and gate from a 4011 nand gate chip is shown below. Study the transfer characteristics of a ttl nand gate using a 7400 chip. Basically we use the first gate of the 4011 as the gate where we have our inputs. The nand gate is significant because any boolean function can be implemented by using a combination of nand gates.
