What is the input of AND gate?
The AND gate is a basic digital logic gate that implements logical conjunction (∧) from mathematical logic – it behaves according to the truth table above. A HIGH output (1) results only if all the inputs to the AND gate are HIGH (1). If none or not all inputs to the AND gate are HIGH, LOW output results.
Does gate have 4 inputs?
However, commercial available AND gate IC’s are only available in standard 2, 3, or 4-input packages. If additional inputs are required, then standard AND gates will need to be cascaded together to obtain the required input value, for example.
Which input values will cause an AND logic gate?
3. Which input values will cause an AND logic gate to produce a HIGH output? Explanation: For AND gate, the output is high only when both inputs are high. That’s why the high output in AND will occurs only when all the inputs are high.
Which logic gate provides high output for input?
A logic circuit that provides a HIGH output for both inputs HIGH or both inputs LOW is a(n):
| 1) | NAND gate |
|---|---|
| 2) | OR gate |
| 3) | Ex-OR gate |
| 4) | Ex-NOR gate |
| 5) | NULL |
Which gate is called a coincidence gate?
X-NOR gate is also known as coincidence detector or equivalence detector. The output of OR gate is high when any one of the inputs is high and output of OR gate is low only when all inputs are low. Therefore, the output of NOR gate is high only when all inputs are low.
Which is the output of a logic gate?
AND gate: the output is 1 if all inputs are 1; otherwise, the output is 0. OR gate: the output is 1 if at least one input is 1; otherwise, the output is 0. XOR gate: the output is 0 if both inputs are same; otherwise, the output is 1. NAND gate: the output is 1 if at lease one input is 0; otherwise, the output is 0.
When is the XOR gate output at logic 1?
The XOR gate output is at logic 1 when and only one of its inputs is at logic 1. Otherwise the output is at logic 0. The XNOR gate output is at logic 0 when one and only one of its inputs is at logic 1 Otherwise the output is at logic 1. (It is therefore similar to the XOR gate, but its output is inverted).
When is the NAND gate output at logic 0?
The NAND gate output is at logic 0 when & only when all its inputs are at logic 1. Otherwise the output is at logic 0. The NOR gate output is at logic 0 when one or more of its inputs are at logic 1. If all of its inputs are at logic 0, the output is at logic 1.
Which is true about the 2 input AND gate?
The 2-input logic AND gate is the most known, although it can have many more inputs (A, B, C, etc.), but it only has one output: Q. The 2-input and the 3-input AND gates have the above truth tables. It is easy to see that the output Q is “1” (true) when the input A and B are both “1”. In other words, the output Q is “1” when A and B inputs are “1”.
