and prices please contact

the Semiconductor Group Offices in

Germany or the Siemens Companies and

Representatives worldwide

(see address list).

Due to technical requirements compo-

nents may contain dangerous substanc-

es. For information on the types in ques-

tion please contact your nearest

ufacturer.

Packing

Please use the recycling operators

known to you. We can also help you – get

in touch with your nearest sales office. By

agreement we will take packing material

back, if it is sorted. You must bear the

costs of transport.

For packing material that is returned to us

unsorted or which we are not obliged to

accept, we shall have to invoice you for

any costs incurred.

Components used in life-support de-

vices or systems must be expressly

authorized for such purpose!

Critical components 1 of the Semiconduc-

tor Group of Siemens AG, may only be

used in life-support devices or systems 2

with the express written approval of the

Semiconductor Group of Siemens AG.

1 A critical component is a component

used in a life-support device or system

whose failure can reasonably be

expected to cause the failure of that

life-support device or system, or to

affect its safety or effectiveness of that

device or system.

2 Life support devices or systems are

intended (a) to be implanted in the

human body, or (b) to support and/or

maintain and sustain human life. If

they fail, it is reasonable to assume

that the health of the user may be

endangered.

Data Classification

Maximum Ratings

Maximum ratings are absolute ratings; exceeding only one of these values may cause

irreversible damage to the integrated circuit.

Recommended Operating Conditions

Under this conditions the functions given in the circuit description are fulfilled. Nominal

conditions specify mean values expected over the production spread and are the

proposed values for interface and application. If not stated otherwise, nominal values will

apply at T A =25°C and the nominal supply voltage.

Characteristics

The listed characteristics are ensured over the operating range of the integrated circuit.
