description
This single 2-input exclusive-OR gate is designed for 1.65-V to 5.5-V VCC operation.
The SN74LVC1G86 performs the Boolean function Y = A ⊕ B or Y = AB + AB in positive logic.
A common application is as a true/complement element. If the input is low, the other input is reproduced in true
form at the output. If the input is high, the signal on the other input is reproduced inverted at the output.
This device is fully specified for partial-power-down applications using I
preventing damaging current backflow through the device when it is powered down.
The SN74LVC1G86 is characterized for operation from –40°C to 85°C.

exclusive-OR logic
An exclusive-OR gate has many applications, some of which can be represented better by alternative
logic symbols.
EXCLUSIVE OR
= 1
These are five equivalent exclusive-OR symbols valid for an SN74LVC1G86 gate in positive logic; negation may be shown at any two ports.
LOGIC-IDENTITY ELEMENT EVEN-PARITY ELEMENT ODD-PARITY ELEMENT
= 2k 2k + 1
The output is active (low) if
all inputs stand at the same
logic level (i.e., A = B).
The output is active (low) if
an even number of inputs
(i.e., 0 or 2) are active.
The output is active (high) if
an odd number of inputs
(i.e., only 1 of the 2) are
active.
