*1 : The switching threshold voltage of Single-End-Receiver of USB I/O buffer is set as within VIL (Max) = 0.8V,
VIH (Min) = 2.0 V (TTL input standard).
There are some hystereses 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
0.8 V to 2.5 V to the local ground reference level.
Above voltage range is the common mode input voltage range.
