8 / 16 page  © 2005 Fairchild Semiconductor Corporation www.fairchildsemi.com USB1T1103 Rev. 1.0. 3 8 DC Electrical Characteristics Supply Terminals Over recommended range of supply voltage and operating free air temperature (unless otherwise noted). VCC (5V) = 4.0V to 5.5V or VREG (3.3V) = 3.0V to 3.6V, VCCIO = 1.65V to 3.6V. Notes: 9. ILOAD includes the pull-up resistor current via terminal VPU 10. The minimum voltage in Suspend mode is 2.7V. 11. Not tested in production, value based on characterization. 12. Excludes any current from load and VPU current to the 1.5kΩ resistor. 13. Includes current between Vpu and the 1.5k internal pull-up resistor. 14. When VCCIO < 2.7V, minimum value for VREGTH = 2.0V for supply present condition. 15. DC electrical measurements should be taken with unused inputs and I/O pins connected to a valid logic level. This applies for all modes of device operation defined in the Functional Tables on Page 4.
