NOTES:
1. Unless otherwise noted, all specifications in this table apply to all processor frequencies.
2. All outputs are open-drain.
3. V
and V
may experience excursions above V
CC
. However, input signal drivers must comply with the
signal quality specifications in Section 3.0.
4. The V
referred to in these specifications refers to instantaneous V
CC
.
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
as indicated in
Figure 8
for the
Asynchronous GTL+ signals.
9. Leakage to V
SS
with pin held at V
.
10.Leakage to V
CC
with pin held at 300 mV.
