Minimum and maximum times are evaluated at 80 pF equivalent load. Actual test capacitance may vary, and results should be correlated
to these specifications.
REQ* and GNT* are the only point-to-point signals and have different output valid delay and input setup times than bused signals. GNT*
has a setup of 10.
For purposes of active/float timing measurements, the high-Z or off state is when the total current delivered through the component pin
is less than or equal to the leakage current specification at 80 pF equivalent load.
