Figure 23 shows the typical output drive characteristics of FLEX 10KE
devices with 3.3-V and 2.5-V V_CCIO. The output driver is compliant to the
3.3-V PCI Local Bus Specification, Revision 2.2 (when VCCIO pins are
connected to 3.3 V). FLEX 10KE devices with a -1 speed grade also comply
with the drive strength requirements of the PCI Local Bus Specification,
Revision 2.2 (when VCCINT pins are powered with a minimum supply of
2.375 V, and VCCIO pins are connected to 3.3 V). Therefore, these devices
can be used in open 5.0-V PCI systems.
