Notes:

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

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.

3 - Vpull-up(external) = 2.7V, Min=Vpull-up(external)/2-150mV; Max=Vpull-up(external)/2 +150mV
