Notes:
1. Currents are measured at high temperature (100°C junction temperature) and maximum voltage.
2. Currents are measured at 85°C junction temperature.
AC loadings are defined per the PCI/PCI-X specifications for the datapath; Microsemi loadings for enable
path characterization are described in Figure 2-10.
