1. The maximum PCI input voltage depends upon the operating mode of the PCI bus, which
PCI5VBIAS determines. The maximum input voltage in a 5 V PCI system is 5 V. The maximum input
voltage in a 3.3 V PCI system is VDD. Refer to the signal description in
Section 3.9, “Power and
Ground Pins,” for more information concerning PCI5VBIAS.
