exclusive-OR logic
|
An exclusive-OR gate has many applications, some of which can be represented better by alternative logic symbols. 
These five equivalent exclusive-OR symbols are valid for an SN74LV1T86 gate in positive logic; negation may be shown at any two ports. EXCLUSIVE OR |
||
The output is active (low) if all inputs stand at the same logic level (i.e., A = B). LOGIC-IDENTITY ELEMENT |
The output is active (low) if an even number of inputs (i.e., 0 or 2) are active. EVEN-PARITY ELEMENT |
The output is active (high) if an odd number of inputs (i.e., only 1 of the 2) are active. ODD-PARITY ELEMENT |
