*Stresses exceeding those listed in this section could cause permanent damage to the device. This is
a stress rating only. Exposure to absolute maximum rating conditions for extended periods may affect
device reliability. Functional operation of the device at any condition exceeding those indicated in
Section 3.2, "Operating
of this specification is not implied. Note, device signals are NOT 5 volt tolerant unless specified
otherwise.

**Proper operation of LAN9500/LAN9500i is guaranteed only within the ranges specified in this section.
When powering this device from laboratory or system power supplies, it is important that
the absolute maximum ratings not be exceeded or device failure can result. Some power
supplies exhibit voltage spikes on their outputs when AC power is switched on or off. In
addition, voltage transients on the AC power line may appear on the DC output. If this
possibility exists, it is suggested that a clamp circuit be used.
This rating does not apply to the following pins: XI, XO, EXRES, USBRBIAS.
This rating does not apply to the following pins: EXRES, USBRBIAS.
