TELEFUNKEN Semiconductors
TDA 4565
Picture improvement circuit for colour TV
Technology: Bipolar
Integrated, matchable gyrator chain, adjustable in steps
of 45 ns from 730 to 1045 ns
(R–Y) and (B–Y), suitable for pos. and neg. colour
difference signals
Steepens the slope of the colour difference signals
Y-output with less delay for applications with future
features (i.e. modulation of horizontal deflection)
Case: 18-pin dual inline plastic

OZONE DEPLETING SUBSTANCES POLICY STATEMENT
It is the policy of TEMIC TELEFUNKEN microelectronic GmbH to
1. Meet all present and future national and international statutory requirements and
2. Regularly and continuously improve the performance of our products, processes, distribution and operating systems
with respect to their impact on the health and safety of our employees and the public, as well as their impact on the
environment.
Of particular concern is the control or elimination of releases into the atmosphere of those substances which are known
as ozone depleting substances ( ODSs ).
The Montreal Protocol ( 1987 ) and its London Amendments ( 1990 ) will soon severely restrict the use of ODSs and forbid
their use within the next ten years. Various national and international initiatives are pressing for an earlier ban on these
substances.
TEMIC TELEFUNKEN microelectronic GmbH semiconductor division has been able to use its policy of continuous
improvements to eliminate the use of any ODSs listed in the following documents.
1. Annex A, B and list of transitional substances of the Montreal Protocol and the London Amendments respectively
2 . Class I and II ozone depleting substances in the Clean Air Act Amendments of 1990 by the Environmental Protection
Agency ( EPA ) in the USA and
3. Council Decision 88/540/EEC and 91/690/EEC Annex A, B and C ( transitional substances ) respectively.
TEMIC can certify that our semiconductors are not manufactured with and do not contain ozone depleting substances.
We reserve the right to make changes to improve technical design without further notice .
Parameters can vary in different applications. All operating parameters must be validated for each customer
application by the customer. Should the buyer use TEMIC products for any unintended or unauthorized application,
the buyer shall indemnify TEMIC against all claims, costs, damages, and expenses, arising out of, directly or
indirectly, any claim of personal damage, injury or death associated with such unintended or unauthorized use.
