- why NAND AND NOR gates alone are used to form a LATCH circuit
Why we cannot make a LATCH circuit with logic gates other than NAND and NOR gates.?
I think you can. However, recognize that all combinatorial logic can be (in fact often are) constructed from NAND and NOR gates. The fundamental boolean operations are AND, OR, and INVERT (or NOT), everything can be constructed from these. For technical reasons, it is usually easier to just make NAND and NOR gates as the basis for all higher complexity digital circuits in ICs.Avanthica said:TL;DR Summary: why NAND AND NOR gates alone are used to form a LATCH circuit

Because you need an inverter somewhere in a latch. Try to design a latch without a NOT gate and see what happens.Avanthica said:Why we cannot make a LATCH circuit with logic gates other than NAND and NOR gates.?
It is certainly possible, and even NAND and NOR gates can be made of inverters, AND gates, and OR gates.Avanthica said:TL;DR Summary: why NAND AND NOR gates alone are used to form a LATCH circuit

NAND and NOR gates are necessary for latch circuits because they are the basic building blocks of digital logic circuits. Latch circuits require these gates to function as they are responsible for performing logical operations such as AND, OR, and NOT.
NAND and NOR gates play a crucial role in latch circuits as they are used to create a feedback loop which allows the circuit to store and retain a logic state, known as a latch. This is necessary for memory storage and data processing in digital systems.
While other logic gates such as AND, OR, and NOT gates can be used in latch circuits, NAND and NOR gates are preferred due to their simplicity and efficiency in performing logical operations. They also require fewer components, making them more cost-effective.
In latch circuits, NAND and NOR gates are connected in a feedback loop, with their outputs connected to each other's inputs. This creates a latch, where the output of one gate feeds into the input of the other and vice versa. This allows the circuit to retain a logic state, which can be changed by applying a triggering signal to the inputs.
No, NAND and NOR gates are used in various digital logic circuits, including flip-flops, shift registers, and counters. They are also used in combinational logic circuits to perform logical operations. However, their use in latch circuits is essential for memory storage and data processing in digital systems.
