MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -Course Hero uses AI to attempt to automatically extract content from documents to surface to you and others so you can study better, e.g., in search results, to enrich docs, and more.

Detailed explanation-2: -NAND gates can also reduce the cost of manufacturing a circuit since it is possible to reduce the total number of chips needed by the circuit. This duality of functions can be used to save money in the manufacture of logic circuits.

Detailed explanation-3: -A NAND gate is a universal logic gate which performs the negated logical multiplication. A NOR gate is a universal logic gate which performs the negated logical addition. NAND gate can be implemented by using an AND gate followed by a NOT gate.

Detailed explanation-4: -The 74LVC2G02 is a dual 2-input NOR gate. Inputs can be driven from either 3.3 V or 5 V devices. This feature allows the use of these devices as translators in mixed 3.3 V and 5 V environments. Schmitt-trigger action at all inputs makes the circuit tolerant of slower input rise and fall times.

Detailed explanation-5: -To make a NOR gate perform the NAND function, we must invert all inputs to the NOR gate as well as the NOR gate’s output. For a two-input gate, this requires three more NOR gates connected as inverters.
