*1 : The switching threshold voltage of 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 are some hysteresis 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.
