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.
