Note 7.1

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.

Note 7.2

This rating does not apply to the following pins: XTAL1/CLKIN, XTAL2, EXRES1.

Note 7.3

This rating does not apply to the following pins: EXRES1.

*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 7.2, "Operating Conditions**", Section 7.6, "DC Electrical Specifications", or any other

applicable section of this specification is not implied.

Note: Do not drive input signals without power supplied to the device.

Note: Apply and remove power to all power supply pins simultaneously, including the Ethernet

magnetics. Do not apply power to individual supply pins without the others.

**Proper operation of the LAN9211 is guaranteed only within the ranges specified in this section.
