Datasheet
NOTES:
1. These values are only applicable in 3.3 V signaling environments. Outside of this limit the input buffer must
consume its minimum current.
2. Input leakage currents include high-Z output leakage for all bidirectional buffers with tri-state outputs.
3. Signals without pull-up resistors have 3 mA low output current; and signals requiring pull-up resistors, 6 mA.
The signals requiring pull-up resistors include: FRAME#, TRDY#, IRDY#, DEVSEL#, STOP#, SERR# and
PERR#
.
4. This value is characterized but not tested.
