Note 1: All output leakage’s are measured with the current pins in high impedance

Note 2: Output leakage is measured with the low driving output off, either for a high level output or a high impedance

state.

Note 3: Voltages are measured from the local ground potential, unless otherwise specified.

Note 4: This minimum value is referred to as VIL in the USB Spec 1.1

Note 5: This maximum value is referred to as VIH in the USB Spec 1.1

Note 6: This input sensitivity is valid when both differential data inputs are in the differential common

mode range.
