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 Section 3.
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 8.
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 Ω as indicated in Figure 8 for the
Asynchronous GTL+ signals.
9. Leakage to VSS with pin held at VCC
.
10.Leakage to VCC with pin held at 300 mV.
