Applications
The SN74LVC2G86DCUR is commonly used in various digital logic circuits where exclusive-OR operations are required. It can serve as a true/complement element, where if one input is low, the other input is reproduced in true form at the output, and if the input is high, the signal on the other input is reproduced inverted at the output. This device is particularly useful in partial-power-down applications due to its Ioff circuitry, which prevents damaging current backflow when the device is powered down.
