Electrical Specifications
Note 1. Actual value is adjustable. Values in this table require VADJ[2:0] = 4 (011b):
Note 2. USB v1.1 compliance is achieved with external crimp protection diodes.
Note 3. The following SMB I/Os are limited to an input high max of V
Note 4. This parameter is sometimes referred to as TRI-STATE leakage.
Note 5. V
Note 6. A
Note 7. No pull-ups/downs on PCI, IDE, and SMB I/O cell types.

The single ended receiver incorporates hysteresis for more reliable operation.
Under any mode of operation, the USB inputs do not meet the requirements of “Figure 7-1 Maximum Input Wave-
form For USB Signaling” from the USB Specification v1.1. The maximum voltage can not exceed the value above.
