POWER SUPPLY
There are two power supplies in SN65LVDS4, VCC which is the core power supply and VDD which is the output
drive power supply. For proper device operation it is recommended that VCC should be powered up first and
then VDD or VCC applied at the same time as VDD (VCC and VDD tied together). It is also recommended that
VCC should be equal to or less than VDD as shown in Table 3.
