DATA SHEET

USE IN LIFE SUPPORT DEVICES OR SYSTEMS MUST BE EXPRESSLY AUTHORIZED.

SGS-THOMSON PRODUCTS ARE NOT AUTHORIZED FOR USE AS CRITICAL COMPONENTS IN LIFE SUPPORT DEVICES OR SYS-

TEMS WITHOUT THE EXPRESS WRITTEN APPROVAL OF SGS-THOMSON Microelectronics.

As used herein :

1. Life support devices or systems are those which (a) are

intended for surgical implant into the body, or (b) support

or sustain life, and whose failure to perform, when prop-

erly used in accordance with instructions for use pro-

vided with the product, can be reasonably expected to

result in significant injury to the user.

2. A critical component is any component of a life support

device or system whose failure to perform can reason-

ably be expected to cause the failure of the life support

device or system, or to affect its safety or effectiveness.
