TTL 74 86 series or CMOS 4030
Not sure about the comparator. XOR is what I came up with, so we have two XORs. This is the "exclusive OR" logic function. Build one out of standard resistors and transistors, or buy an IC with the XOR function already implemented, or use four two-input NAND gates. At least that's the way we did it in the 1960s. In analog circuits, a comparator.
7432 ICs are used for summing purposesThe 7432 is a quad dual input OR gate. That means that the device contains four identical two input OR gates. It is often in a 14 pin package, and as each gate has three connections, there are 12 logic pins, a ground pin, and a power supply (5 volts) pin, making a total of 14 pins.Seehttp://html.alldatasheet.com/html-pdf/51073/FAIRCHILD/7432/403/1/7432.htmlFor a datasheet.
You can use a second gate on the same IC to invert the output (most OR-gate ICs I know of have 4 gates per chip). Do this by tying the output of the first gate to both inputs of the spare gate.
As I check there is no summon outstanding maybe not blacklisted yet....
A: It is an IC which contain an led which will couple the input to another device within the package it can be a transistor a triac scr and so forth. is main purpose in application is to isolate the source from the output.
If you look at the 7486 IC datasheet you can see, it have 4 independence XOR gates with 2 inputs. So you can only use 2 inputs if you see it like that. But if you understand the truth table of XOR gate you can have 3 input application using 7486 IC. Here I will show you how. 1.Get the first 2 input into the first XOR gate. 2.Then get the 3rd input together with the Output from the first 2 input XOR gate into another gate. 3.This output should be the result of 3 input XOR gate. Check this output with 3 input truth table to confirm the answer.
For two input AND gate it is 7408for three input AND gate it is 7411

the easiest way to make an xnor gate is with a 7486 (or equivalent) integrated circuit, a quad xor gate. connect the output of one gate to one in put of another gate. connect the other input of the second gate to Vcc. the second xor gate will then act as an inverter.
You can't make XOR out of NOT alone. Mathematically, NOT takes only a single argument, and its gate, an inverter, takes a single input. There's no way to combine two inputs giving a single output with one input gates. You need some two input gates to do the job. They can be AND, OR, NAND, NOR, or some combination, but you need something. That said, they don't have to be IC gates; you can combine two inputs with diodes to make an OR gate, so you could make XOR with only inverters and diodes, i.e. no other gate symbols on your schematic, but it would mot be making XOR out of NOT.

The number of inputs in an OR gate can vary, but the most common type is a 2-input OR gate. This means that it takes two input signals and produces one output signal based on the logical OR operation.
