What is the IC number for 2 input NOR gate?
What is the IC number for 2 input NOR gate?
7402
As with the 7400 series of TTL logic chips, several hundred types of 4000-series chips are available….Digital Electronics: Integrated Circuit Logic Gates.
| Number | Description |
|---|---|
| 7400 | Quad two-input NAND gate (four NAND gates) |
| 7402 | Quad two-input NOR gate (four NOR gates) |
| 7404 | Hex inverter (six NOT gates) |
What is a positive NOR gate?
The Positive Logic NOR gates output achieves its ACTIVE state (LOW) “only when AT LEAST ONE of its inputs” achieve their ACTIVE state (HIGH). Negative Logic NOR gate. The Negative Logic NOR gates output achieves its ACTIVE state (HIGH) “only when ALL of its inputs” achieve their ACTIVE state (LOW).
Which IC is required for NOR gate?
74LS02 is a LOGIC GATE IC and member of 74XXYY IC series which are logic gates. There are four NOR gates in the IC and each gate has two inputs, hence the name QUADRUPLE TWO INPUT NOR GATE.
Why NAND and NOR gates are called 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. Hence the correct option is option (B). Note: NAND and NOR are economical and it is commonly used in many integrated circuit packages.
What is a NOR gate in digital logic?
NOR Gate is a digital logic gate (Also known as Universal gate) which gives output “1” only and only when all of its inputs are logic LOW state “0”. NOR gate is invert of OR Gate.
When is the input NOR gate high or low?
The truth table of 3 –input NOR gate is given below The output of the 3 input NOR gate is LOW when all the 3 inputs are HIGH and it will be HIGH for all other combinations of inputs. Back to top
Can a NOR gate be used to build a computer?
The symbol for a NOR gate is shown below. It is a very simple logic gate: if all inputs are low, the output is high. It might be surprising that NOR gates are sufficient to build a computer, but NOR is a universal gate: you can make any other logic gate out of NOR gates.
When does a NOR gate become a universal gate?
NOR Gate is a digital logic gate (Also known as Universal gate) which gives output “1” only and only when all of its inputs are logic LOW state “0”. NOR gate is invert of OR Gate. In other words, if we connect NOT gate to the output of OR gate that will become NOR gate. NOR gate usually has 2 input And 1 output.
