*1: The switching threshold voltage of the single-end-receiver of USB I/O buffer is set as within VIL (Max) = 0.8 V,
VIH (Min) = 2.0 V (TTL input standard).
There is some hysteresis applied to lower noise sensitivity.
*2: Use differential-receiver to receive USB differential data signal. Differential-receiver has 200 mV of differential input
sensitivity when the differential data input is within 0.8V to 2.5V to the local ground reference level.
Above voltage range is the common mode input voltage range.
