NOTES:
1. VIL is defined as the voltage level at a receiving agent that will be interpreted as a logical low value.
2. VIH is defined as the voltage level at a receiving agent that will be interpreted as a logical high value.
3. VIH and VOH may experience excursions above VCC. However, input signal drivers must comply with the signal
quality specifications in Section 3.
4. Refer to Processor Signal Integrity Models for I/V characteristics.
5. The VTT referred to in these specifications refers to the instantaneous VTT.
6. Leakage to VSS with pin held at VTT.
7. The maximum output current is based on maximum current handling capability of the buffer and is not
specified into the test load.
8. Leakage to VTT with pin held at 300 mV.

NOTES:
1. All outputs are open drain.
2. TAP signal group must meet system signal quality specification in Section 3.
3. Refer to the Processor Signal Integrity Models for I/V characteristics.
4. The VTT referred to in these specifications refers to instantaneous VTT.
5. The maximum output current is based on maximum current handling capability of the buffer and is not
specified into the test load.
6. VHYS represents the amount of hysteresis, nominally centered about 0.5 * VTT for all TAP inputs.
