Power to the device is supplied through the V_CC pin. TI recommends placing a bypass capacitor as close as possible to the supply pin V_CC to help smooth out lower frequency noise to provide better load regulation across the frequency spectrum.

This device doesn't require any power sequencing with respect to other devices in the system due to its power off isolation feature which allows signals to be present on the D± and HSD± pins before the device is powered up without damaging the device.
