NOTES:
1. Unless otherwise noted, all specifications in this table apply to all processor frequencies.
2. V_IL 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 V_IH = GTLREF +
(0.10 * V_TT) and V_IL= GTLREF – (0.10 * V_TT).
4. V_IH is defined as the voltage range at a receiving agent that will be interpreted as a logical high value.
5. V_IH and V_OH may experience excursions above V_TT. However, input signal drivers must comply with the
signal quality specifications.
6. The V_TT referred to in these specifications refers to instantaneous V_TT.
7. All outputs are open drain.
8. The maximum output current is based on maximum current handling capability of the buffer and is not
specified into the test load.
9. Leakage to V_SS with land held at V_TT.
10.Leakage to V_TT with land held at 300 mV.

NOTES:
1. Unless otherwise noted, all specifications in this table apply to all processor frequencies.
2. All outputs are open drain.
3. V_HYS represents the amount of hysteresis, nominally centered about 0.5 * V_TT, for all TAP inputs.
4. The V_TT referred to in these specifications refers to instantaneous V_TT.
