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 ’F86 gate in positive logic; negation may be shown at any two ports.

LOGIC-IDENTITY ELEMENT EVEN-PARITY ELEMENT ODD-PARITY ELEMENT
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 outputs
(i.e., only 1 of the 2) are
active.

†
Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTES: 1. The input voltage ratings may be exceeded provided the input current ratings are observed.
2. The package thermal impedance is calculated in accordance with EIA/JEDEC Std JESD51, except for through-hole packages,
which use a trace length of zero.
