Electrical Specifications
NOTES:
1. Unless otherwise noted, all specifications in this table apply to all processor frequencies.
2. VIL is defined as the maximum voltage level at a receiving agent that will be interpreted as a logical low value.
3. VIH is defined as the minimum voltage level at a receiving agent that will be interpreted as a logical high
value.
4. VIH and VOH may experience excursions above VCC. However, input signal drivers must comply with the
signal quality specifications in Section 3.
5. Refer to processor I/O Buffer Models for I/V characteristics.
6. The VCC referred to in these specifications is the instantaneous VCC.
7. Vol max of 0.450 Volts is guaranteed when driving into a test load of 50
as indicated in Figure 7.
8. Leakage to VSS with pin held at VCC.
9. Leakage to VCC with pin 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. VIH and VOH may experience excursions above VCC. However, input signal drivers must comply with the
signal quality specifications in Chapter 3.0.
4. The VCC referred to in these specifications refers to instantaneous VCC.
5. This specification applies to the asynchronous GTL+ signal group.
6. The maximum output current is based on maximum current handling capability of the buffer and is not
specified into the test load shown in Figure 7.
7. Refer to the processor I/O Buffer Models for I/V characteristics.
8. Vol max of 0.270 Volts is guaranteed when driving into a test load of 50
as indicated in Figure 7 for the
Asynchronous GTL+ signals.
9. Leakage to VSS with pin held at VCC.
10. Leakage to VCC with pin held at 300 mV.
