description
The ’AHC86 devices are quadruple 2-input
exclusive-OR gates. These devices perform the
Boolean function 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 SN54AHC86 is characterized for operation
over the full military temperature range of –55°C
to 125°C. The SN74AHC86 is characterized for
operation from –40°C to 85°C.

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.

†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 af fect device reliability.
NOTES: 1. The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
2. The package thermal impedance is calculated in accordance with JESD 51.
