Which IC number represents ex OR gate?

XNOR gates are represented in most TTL and CMOS IC families. The standard 4000 series CMOS IC is the 4077, and the TTL IC is the 74266 (although an open-collector implementation). Both include four independent, two-input, XNOR gates.

What is the IC number for 3-input OR gate?

74×00 – 74×99

Is there a 3-input XOR gate?

For 3-input XOR gates, we can have the HIGH input when odd numbers of inputs are at HIGH level. So the 3-input OR gate is called as “Odd functioned OR gate”.

What is IC number for 3 input ex-or gate?

Take any two inputs and run them through an XOR like 74135. Take the output from this XOR and use it as the input to a second XOR. The other input to the second XOR is your third input. The output of the second XOR is your desired output.

Which is the 3 input XOR gate Boolean function?

The Boolean function for the 3- input XOR gate is: Q = A ⊕ B ⊕ C = A B C + A B C + A B C + A B C The truth table and logic symbol for 3-input XOR gate is given below. 3-Input Ex-OR Gate Logic Symbol

When does an ex-or gate give an output value?

In general, an Ex-OR gate will give an output value of logic “1” ONLY when there are an ODD number of 1’s on the inputs to the gate, if the two numbers are equal, the output is “0”. Then an Ex-OR function with more than two inputs is called an “odd function” or modulo-2-sum (Mod-2-SUM), not an Ex-OR. This description can be expanded to apply

When does an Exclusive NOR gate have a high input?

For Exclusive NOR gates, we can have the HIGH input when even numbers of inputs are at HIGH level. So the 3-input XNOR gate is called as “Even functioned OR gate”.The truth table and logic symbol for 3-input XNOR gate is given below.
