Single XOR gate that runs on anything from 1.8V to 5V
The SN74LVC1G86DCKT single 2-input XOR gate operates from 1.65V to 5.5V supply.
32 mA output — enough to drive a LED or a small relay
That lets you drive an indicator LED or a low-current relay coil directly, skipping a separate transistor buffer. Quiescent current maxes at 10 µA, so it is not going to drain a battery-powered design.
4 ns propagation delay at 5V — fast enough for most buses
The input logic thresholds are 0.7V–0.8V for low and 1.7V–2.0V for high, which are compatible with 1.8V CMOS and 3.3V LVTTL levels.
