Notes1

NOTES:

1. Unless otherwise noted, all specifications in this table apply to all processor frequencies.

VIL

Input Low Voltage

0.0

VTT/2 – (0.10 * VTT)V

2, 3

2. VIL is defined as the voltage range at a receiving agent that will be interpreted as a logical low value.

3. LINT0/INTR and LINT1/NMI use GTLREF as a reference voltage. For these two signals VIH = GTLREF +

(0.10 * VTT) and VIL= GTLREF – (0.10 * VTT).

VIH

Input High Voltage

VTT/2 + (0.10 * VTT)VTT

4, 5, 6, 3

4. VIH is defined as the voltage range at a receiving agent that will be interpreted as a logical high value.

5. VIH and VOH may experience excursions above VTT. However, input signal drivers must comply with the

signal quality specifications.

6. The VTT referred to in these specifications refers to instantaneous VTT.

VOH

Output High Voltage

0.90*VTT

7, 5, 6

7. All outputs are open drain.

IOL

Output Low Current

VTT/

[(0.50*RTT_MIN)+(RON_MIN)]

8. The maximum output current is based on maximum current handling capability of the buffer and is not

specified into the test load.
