FEATURES
?Very low supply current
?Photo detector and preamplifier in one package ?Internal filter for PCM frequency ?Improved shielding against EMI
?Supply voltage: 2.5 V to 5.5 V
?Improved immunity against ambient light ?Insensitive to supply voltage ripple and noise
?Component in accordance to RoH S 2002/95/EC and WEEE 2002/96/EC
DESCRIPTION
The TSOP341.., TSOP343.. series are miniaturized receivers for infrared remote control systems. A PIN diode and a preamplifier are assembled on a lead frame, the epoxy package acts as an IR filter.
The demodulated output signal can be directly decoded by a microprocessor. The TSOP341.. is compatible with all common IR remote control data formats. The TSOP343.. is optimized to better suppress spurious pulses from energy saving fluorescent lamps but will also suppress some data signals.
This component has not been qualified according to automotive specifications.

SUITABLE DATA FORMAT
The TSOP341.., TSOP343.. series are designed to suppress spurious output pulses due to noise or disturbance signals.Data and disturbance signals can be distinguished by the devices according to carrier frequency, burst length and envelope duty cycle. The data signal should be close to the band-pass center frequency (e.g. 38 kH z) and fulfill the conditions in the table below.
When a data signal is applied to the TSOP341.., TSOP343..in the presence of a disturbance signal, the sensitivity of the receiver is reduced to insure that no spurious pulses are present at the output. Some examples of disturbance signals which are suppressed are:
?DC light (e.g. from tungsten bulb or sunlight)?Continuous signals at any frequency
?Modulated noise from fluorescent lamps with electronic ballasts (see figure 14 or figure 15)

OZONE DEPLETING SUBSTANCES POLICY STATEMENT
It is the policy of Vishay Semiconductor GmbH to
1.Meet all present and future national and international statutory requirements.
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. It is particular concern to control or eliminate releases of those substances into the atmosphere which are known as ozone depleting substances (ODSs).
The Montreal Protocol (1987) and its London Amendments (1990) intend to 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. Vishay Semiconductor GmbH has been able to use its policy of continuous improvements to eliminate the use of 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.
3.Council Decision 88/540/EEC and 91/690/EEC Annex A, B and C (transitional substances) respectively.
Vishay Semiconductor GmbH can certify that our semiconductors are not manufactured with ozone depleting substances and do not contain such substances.
We reserve the right to make changes to improve technical design
and may do so 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 Vishay Semiconductors products for any unintended or unauthorized application, the buyer shall indemnify Vishay Semiconductors 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.
