(1) These rated numbers are from the PCI Local Bus Specification (version 2.3). The DC specifications and AC specifications are defined in
Table 4-3 and Table 4-4, respectively, of the PCI Local Bus Specification.
(2) PCI-capable pins can withstand a maximum overshoot/undershoot for up to 11 ns as required by the PCI Local Bus Specification
(version 2.3).
(3) Duration of overshoot/undershoot must not exceed 30% of the cycle period.
