DATASHEET
Notes:
1. Output leakage is measured with the current pins in high impedance.
2. See USB 2.0 Specification for USB DC electrical characteristics.
3. RBIAS is a 3.3V tolerant analog pin.
CAPACITANCE TA = 25°C; fc = 1MHz; VDD33CR = 3.3V
Power Sequencing
There are no power supply sequence restrictions for the Hub. The order in which power supplies
power-up and power-down is implementation dependent.
