Pentium
III Processor for the SC242 at 450 MHz to 1.0 GHz
NOTES:
1. Unless otherwise noted, all specifications in this table apply to Pentium
III processor frequencies.
2. V
and V
for the Pentium III processor may experience excursions up to 200 mV above V
TT
for a single
system bus clock. However, input signal drivers must comply with the signal quality specifications in
Section
3.0
.
3. Minimum and maximum V
TT
are given in
Table 11
.
4. Parameter correlated to measure into a 25
resistor terminated to 1.5 V.
5. I
for the Pentium III processor may experience excursions of up to a 12 mA for a single bus clock.
6. Leakage current affects input, output, and I/O signals.

NOTES:
1. Unless otherwise noted, all specifications in this table apply to all Intel
Pentium
III processor frequencies.
2. These values are specified at the processor core pins.
3. These values are specified at the processor edge fingers.
4. Parameter measured at 14 mA (for use with TTL inputs).
5. Leakage current affects input, output and I/O signals.
