Notes:
1. Input leakage currents include hi-Z output leakage for all bidirectional buffers with tristate outputs.
2. Signals without pull-up resistors must have 3 mA low output current. Signals requiring pull-up must have 6 mA; the latter includes
FRAME#, IRDY#, TRDY#, DEVSEL#, STOP#, SERR#, PERR#, LOCK#, and, when used AD[63::32], C/BE[7::4]#, PAR64, REQ64#, and
ACK64#.
3. Absolute maximum pin capacitance for a PCI input is 10 pF (except for CLK).
