Notes
:
1. Nominal voltages; see
Table 4
for recommended operating conditions.
2. For processor bus signals, the reference is OV
DD
while GV
DD
is the reference for the L3 bus signals.
3. Excludes test signals and IEEE 1149.1 boundary scan (JTAG) signals.
4. Capacitance is periodically sampled rather than 100% tested.
5. The leakage is measured for nominal OV
DD
/GV
DD
and V
DD
, or both OV
DD
/GV
DD
and V
DD
must vary in the same
direction (for example, both OV
DD
and V
DD
vary by either +5% or –5%).
6. Applicable to L3 bus interface only.
