What is a 2-input NOR gate?

What is a 2-input NOR gate?

Theory. NOR GATE – ​ It is a digital circuit that has two or more inputs and produces an output, which is the inversion of logical OR of all those inputs.

What is the output of NOR gate for 2-input?

Therefore in the case of the NOR gate, the output is logic one only when all inputs are logic zero. For all other types of combinations of inputs, the output is logic zero. In two input NOR Gate, there are only two input values and an output value.

What is the truth table for the NOR gate?

The NOR gate is a digital logic gate that implements logical NOR – it behaves according to the truth table to the right. A HIGH output (1) results if both the inputs to the gate are LOW (0); if one or both input is HIGH (1), a LOW output (0) results. NOR is the result of the negation of the OR operator.

What is the chip number of 2-input NOR gate?

There are four NOR gates in the IC and each gate has two inputs, hence the name QUADRUPLE TWO INPUT NOR GATE. The gates in the chip are designed by low power SCHOTTKY TRANSISTORS….74LS02 Pin configuration.

Pin Number Description
5 2A-INPUT1 of GATE 2
6 2B-INPUT2 of GATE 2

Is NOR a universal gate?

A universal gate is a gate which can implement any Boolean function without need to use any other gate type. The NAND and NOR gates are universal gates. In practice, this is advantageous since NAND and NOR gates are economical and easier to fabricate and are the basic gates used in all IC digital logic families.

Why NOR gate is known as universal gate?

∴ NAND and NOR gates are called universal gates because they can be combined to produce any of the other gates like OR, AND, and NOT gates.

What is an IC number?

An IC number is allotted at the time of commissioning, based on the individual’s order of merit in IMA. It is a unique five-digit number with an alphabet suffix. These numbers are in sequence, the next course numbers start from the last number of the previous batch.

What is IC number of OR gate?

OR Gate An OR Gate is a basic gate used in digital electronics. It gives the output as the addition of two inputs. The IC number of OR Gate is 7432.

How do you prove that a NOR gate is a universal gate?

One NOR input pin is connected to the input signal A while all other input pins are connected to logic 0. The output will be A’. Thus, the NOR gate is a universal gate since it can implement the AND, OR and NOT functions.

Can a NOR gate be used as an inverter?

An Inverter or logic NOT gate can also be made using standard NAND and NOR gates by connecting together ALL their inputs to a common input signal for example. A very simple inverter can also be made using just a single stage transistor switching circuit as shown.

What is the use of EX OR gate?

It is used in simple digital addition circuits which calculate the sum and carry of two (half-adder) or three (full-adder) bit numbers. XOR gates are also used to determine the parity of a binary number, i.e., if the total number of 1’s in the number is odd or even.

Which gate is equivalent to NOR OR XOR?

– AND — Both Inputs must be ON – OR — One or both inputs must be ON – NOT — Input must be OFF – NAND — At least one input is OFF – NOR — Both inputs OFF – XOR — One input or the other (but not both) must be ON – XNOR — At least one input must be OFF (but not both)

What are logic gates and truth tables?

OR Gate.

  • AND Gate.
  • NOT Gate.
  • NAND Gate.
  • NOR Gate.
  • Exclusive-OR gate (XOR Gate) In XOR gate the output of a two-input XOR gate attains the state 1 if one adds only input attains the state 1.
  • Exclusive-NOR Gate (XNOR Gate) In XNOR gate the output is in state 1 when its both inputs are the same that is,both 0 or both 1.
  • What is a logic gate truth table?

    NOT Gate or an Inverter Truth Table. NOT gate is a single-in single-out logical device where the output will always be the complementary form of the input.

  • AND Gate Truth Table. AND gate is a basic gate with multiple inputs and a single output.
  • OR Gate Truth Table.
  • NAND Gate Truth Table.
  • NOR Gate Truth Table.
  • XOR Gate Truth Table.
  • XNOR Gate Truth Table.
  • What are the 7 basic logic gates?

    For AND Gate – If both the inputs are high then the output is also high

  • For OR Gate – If a minimum of one input is high then the output is High
  • For XOR Gate – If the minimum one input is high then only the output is high
  • NAND Gate – If the minimum one input is low then the output is high
  • NOR Gate – If both the inputs are low then the output is high.
