DC Electrical Specifications
This section details the DC electrical specifications of the LAN9220 I/O buffers. The electrical specifications in this sec-
tion are valid over the indicated voltage range and the temperature range specified in Section 7.2, "Operating Condi-
tions**".
Note:
When operating at reduced VDDVARIO voltage levels (less than 3.0V), do not rely on internal pull-up and
pull-down resistors to determine signal state. Refer to the individual signal descriptions in Section 2.0, "Pin
Description and Configuration" for more information.
