. Measured when the driver is tristated.

6.

This is the measurement at the pin.

1.

Unless otherwise noted, all specifications in this table apply to all processor frequencies.

2.

Measured at 0.2*V

TT

.

3.

V

OH

 is determined by value of the external pullup resistor to V

TT

. Please refer to platform design guide for 

details.

4.

For V

IN

 between 0 V and V

OH

.

5.

This is the measurement at the pin.

1.

These parameters are based on design characterization and are not tested.

2.

All DC specifications for the SMBus signal group are measured at the processor pins.

3.

Platform designers may need this value to calculate the maximum loading of the SMBus and 
to determine maximum rise and fall times for SMBus signals.
