Notes:
1 - Guaranteed by design, not 100% tested in production.
3 - Vpullup(external) = 1.5V, Min = Vpullup(external)/2-150mV; Max=(Vpullup(external)/2)+150mV
2 - VDIF specifies the minimum input differential voltages (VTR-VCP) required for switching, where VTR is the "true"
input level and VCP is the "complement" input level.
