47.8 USB HS Characteristics
The following characteristics are applicable to the operating temperature range: T
A
= -40°C to 85°C and worst case of
power supply, unless otherwise specified.
47.8.1 Electrical Characteristics
47.8.2 Static Power Consumption
Note: 1. If cable is connected, add 200 µA (typical) due to Pull-up/Pull-down current consumption.
