description
These devices contain four independent 2-input
exclusive-OR gates. They perform the Boolean
functions Y = A
⊕
B or Y = AB + AB in positive
logic.
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.
The SN54ALS86 and SN54AS86A are
characterized for operation over the full military
temperature range of − 55°C to 125°C. The
SN74ALS86 and SN74AS86A are characterized
for operation from 0°C to 70°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
′ALS86
or
′AS86A
gate in positive logic. Negation
may be shown at any two ports.
LOGIC-IDENTITY ELEMENT
=
EVEN-PARITY ELEMENT
2k
ODD-PARITY ELEMENT
2k + 1
The output is active (low) if
all inputs are 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.

B. Waveform 1 is for an output with internal conditions such that the output is low except when disabled by the output control.
Waveform 2 is for an output with internal conditions such that the output is high except when disabled by the output control.
C. When measuring propagation delay items of 3-state outputs, switch S1 is open.
D. All input pulses have the following characteristics: PRR
≤
1 MHz, tr = tf = 2 ns, duty cycle = 50%.
E. The outputs are measured one at a time with one transition per measurement.
