1 - Guaranteed by design, not 100% tested in production.

2 - VDIF specifies the minimum input differential voltage (VTR-VCP) required for switching, where VTR is the "true"

input level and VCP is the "complement" input level

3 - Vpullup(external)=1.5V, Min=Vpullup(External)/2-150mV, Max=Vpullup(external)/2+150mV
