3.3 V PCI, 3.3 V PCI-X
Peripheral Component Interface for 3.3 V standard specifies support for 33 MHz and 66 MHz PCI Bus
applications.
AC loadings are defined per the PCI/PCI-X specifications for the datapath; Microsemi loadings for enable
path characterization are described in Figure 2-11.
AC loadings are defined per PCI/PCI-X specifications for the datapath; Microsemi loading for tristate is
described in Table 2-46.

Notes:
1. IIL is the input leakage current per I/O pin over recommended operation conditions where –0.3 V< VIN < VIL.
2. IIH is the input leakage current per I/O pin over recommended operating conditions VIH < VIN< VCCI. Input current is
larger when operating outside recommended ranges.
3. Currents are measured at high temperature (100°C junction temperature) and maximum voltage.
4. Currents are measured at 85°C junction temperature.
