DESCRIPTION/ORDERING INFORMATION (CONTINUED)
A common application is as a true/complement element. If one of the inputs is low, the other input is reproduced
in true form at the output. If one of the inputs is high, the signal on the other input is reproduced inverted at the
output.
EXCLUSIVE-OR LOGIC
= 1
EXCLUSIVE OR
These five equivalent exclusive-OR symbols are valid for an SN74LVC86A gate in positive logic; negation may be shown at any two ports.
=
2k
2k + 1
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 inputs
(i.e., only 1 of the 2) are
active.

QUADRUPLE 2-INPUT EXCLUSIVE-OR GATES
SCAS288P–JANUARY 1993–REVISED APRIL 2005
Inputs can be driven from either 3.3-V or 5-V devices. This feature allows the use of these devices as translators
in a mixed 3.3-V/5-V system environment.

An exclusive-OR gate has many applications, some of which can be represented better by alternative logic
symbols.
