description
The ’AHCT86 devices are quadruple 2-input
exclusive-OR gates. These devices perform the
Boolean function Y = A ⊕ B or Y = A
positive logic.
The SN54AHCT86 is characterized for operation
over the full military temperature range of –55°C
to 125°C.The SN74AHCT86 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 SN74AHCT86 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.

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 and output voltage ratings may be exceeded if the input and output current ratings are observed.
