Note 5.1

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 5.2

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

Note 5.3

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

Note 5.4

0oC to +85oC for extended commercial version, -40oC to +85oC for industrial version.

Note 5.5

Performed by independent 3rd party test facility.

*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 5.2, "Operating Conditions**", Section 5.1, "Absolute Maximum Ratings*", or any other

applicable section of this specification is not implied. Note, device signals are NOT 5 volt tolerant

unless specified otherwise.
