Notes:
1. Input leakage currents include high impedance output leakage for all bi-directional buffers with tri-state out-
puts.
2. Signals without pull-up resistors have greater than 3mA low output current. Signals requiring pull resistors
have greater than 6mA output current. The latter include FRAME, TRDY, IRDY, STOP, SERR, PERR.
3. Absolute maximum pin capacitance for a PCI unit is 10pF (except for CLK).
4. Lower capacitance on this input-only pin allows for non-resistive coupling to AD[xx].
