Why NAND Gate is Better than NOR Gate?
Digital logic gates of the NAND and NOR kinds both carry out logical negation or “inversion,” of an input signal. As they can be used to implement any Boolean function, NAND gates and NOR gates are referred to as “universal” gates.
The fact that NAND gates are easier and more effective to implement using MOSFETs (metal-oxide-semiconductor field-effect transistors), the most popular form of the transistor in VLSI (very large-scale integration) circuits, is one reason why NAND gates are frequently regarded as superior to NOR gates. NAND gates are more compact and less expensive to produce than NOR gates since they implement the same logical function with fewer transistors.
NAND gates also possess the quality of being “functionally complete,” which entails that every Boolean operation can be carried out just by NAND gates. NAND gates are a flexible and adaptable building block for digital logic circuits a result.
In some cases, NOR gates have a few advantages over NAND gates. For instance, because of their simpler transistor structure, NOR gates are often faster than NAND gates. Additionally, NOR gates use less energy than NAND gates, which is beneficial in low-power applications. In most VLSI circuits, the simplicity and cost advantages of NAND gates frequently exceed these advantages.
