(1) For test conditions shown as MIN, MAX, or NOM, use the appropriate value specified in the recommended operating conditions table.
(2) These rated numbers are from the PCI Local Bus Specification (version 2.3). The DC specification and AC specifications are defined in
Table 4-3 and Table 4-4, respectively, of the PCI Local Bus Specification.
(3) I
I
applies to input-only pins and bi-directional pins. For input-only pins, I
I
indicates the input leakage current. For bi-directional pins, I
I
includes input leakage current and off-state (hi-Z) output leakage current.
(4) PCI input leakage currents include Hi-Z output leakage for all bidirectional buffers with 3-state outputs.
