Can NOR gate have 3 inputs?
Can NOR gate have 3 inputs?
As with the OR function, the NOR function can also have any number of individual inputs and commercial available NOR Gate IC’s are available in standard 2, 3, or 4 input types. If additional inputs are required, then the standard NOR gates can be cascaded together to provide more inputs for example.
What is the input of 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 a 3-input NOR gate?
description. These devices contain three independent 3-input positive-NOR gates. They perform the Boolean functions Y = A • B • C or Y = A + B + C in positive logic. The SN54ALS27A and SN54AS27 are characterized for operation over the full military temperature range of −55°C to 125°C.
How many inputs and outputs does a NOR gate have?
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. There are a total of 4 possible combinations of inputs.
Can a NOR gate have one input?
An AND gate gives a 1 output when both inputs are 1. Therefore, an AND gate is made by inverting the inputs of a NOR gate….AND.
| Input A | Input B | Output Q |
|---|---|---|
| 0 | 1 | 0 |
| 1 | 0 | 0 |
| 1 | 1 | 1 |
When the inputs to a 3 input NOR gate are 001 the output is low?
LOW. When the inputs to a 3-input OR gate are 001, the output is 1. An application requires a 3-input AND gate; however, all three of the inputs actually produce a LOW when the inputs are ON.
What is NOR in circuit?
A NOR gate (“not OR gate”) is a logic gate that produces a high output (1) only if all its inputs are false, and low output (0) otherwise. Hence the NOR gate is the inverse of an OR gate, and its circuit is produced by connecting an OR gate to a NOT gate.
What is the IC number of 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….74LS02 Pin configuration.
| Pin Number | Description |
|---|---|
| 6 | 2B-INPUT2 of GATE 2 |
| 4 | 2Y-OUTPUT of GATE2 |
| NORGATE 3 | |
| 8 | 3A-INPUT1 of GATE 3 |
How many entries will be in the truth table of a 3 input NOR gate?
question. Answer: Total 8 entries will be entered in the truth table of a 3 input NAND gate.
