2-Input Exclusive-OR Gates
Quad 2-input Exclusive-OR gate
An Exclusive-OR [XOR] has a single output that goes high [logic 1] only when the inputs are different. When the inputs are the same the output goes low, see the true table below.

The graphic above shows the logic symbol and pin out for a 7486 Exclusive-OR gate in a 14 pin package.
Exclusive OR Gate Internal Schematic
Note that the internal schematic of a 7486 only applies to the DIP package, as other packages may have a different internal structure [because of assurance levels, not because of the physical package change]. More importantly any of the sub-TTL families will certainly use different resistor values. For example a 74S86 XOR gate may use smaller resistor values than a 74LS86 XOR gate. The smaller resistor values allow the transistors to switch faster but also allow a higher current to flow. So a 74LS86 is slower and consumes less power than a 74S86 IC.
