Notes:

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

2 - VmF 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(extemal) = 1.5V, Min= (Vpull-up(extema1/2) - l50mV; Max = (Vpull-up(extema1/2)+150mV
