Note:
1. Input leakage currents include hi-Z output leakage for all bi-directional buffers with tri-state
outputs.
2. Refer to PCI spec.
3. Inputs are not “5 volt safe.”
4. IIL may be changed on IC and ID pins (up to 200µA), if pulled against internal pull-downs. Refer
to the pin descriptions (Table 1).
5. Do not violate processor or chipset specifications regarding the INIT# pin voltage.
