Input leakage currents include high-impedance output leakage for all bidirectional buffers with tristate outputs.
Signals without pull-up resistors must have 3-mA low output current. Signals requiring pull-up resistors (including
frame_l, trdy_l, irdy_l, devsel_l, stop_l, serr_l, and perr_l) must have 6 mA.
Parameter design guarantee.
