Minimum and maximum times are evaluated at 50 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 do bused
signals. GNT* has a setup of 10 ns; REQ* has a setup of 12 ns for 33 MHz.
For purposes of active/float timing measurements, the hi-Z or off state is defined to be when the total current delivered through
the component pin is less than or equal to the leakage current specification at 50 pF equivalent load.
