IR Receiver Modules for Remote Control Systems
DescriptionThe TSOP341.. - series are miniaturized receivers forinfrared remote control systems. PIN diode andpreamplifier are assembled on lead frame, the epoxypackage is designed as IR filter.The demodulated output signal can directly bedecoded by a microprocessor. The main benefit is theoperation with short burst transmission codes andhigh data rates at a supply voltage of 3 V.
Features • Photo detector and preamplifier in one
package • Internal filter for PCM frequency • Improved shielding against electrical
field disturbance • TTL and CMOS compatibility • Output active low • Supply voltage range: 2.7 V to 5.5 V • High immunity against ambient light • Lead (Pb)-free component • Component in accordance to RoHS 2002/95/EC
and WEEE 2002/96/EC
Special Features • Enhanced data rate up to 4000 bit/s • Operation with short short bursts possible
(≥ 6 cycles/burst)

Suitable Data FormatThe circuit of the TSOP341.. is designed in that waythat unexpected output pulses due to noise or distur-bance signals are avoided. A bandpass filter, an inte-grator stage and an automatic gain control are usedto suppress such disturbances.The distinguishing mark between data signal and dis-turbance signal are carrier frequency, burst lengthand duty cycle.The data signal should fulfill the following conditions:• Carrier frequency should be close to center fre-quency of the bandpass (e.g. 38 kHz).• Burst length should be 6 cycles/burst or longer.• After each burst which is between 6 cycles and 70cycles a gap time of at least 10 cycles is necessary.• For each burst which is longer than 1.8 ms a corre-sponding gap time is necessary at some time in thedata stream. This gap time should have at least samelength as the burst.• Up to 2200 short bursts per second can be receivedcontinuously.Some examples for suitable data format are: NECCode, Toshiba Micom Format, Sharp Code, RC5Code, RC6 Code, RCMM Code, R-2000 Code,RECS-80 Code.When a disturbance signal is applied to theTSOP341.. it can still receive the data signal. How-ever the sensitivity is reduced to that level that nounexpected pulses will occur.Some examples for such disturbance signals whichare suppressed by the TSOP341.. are:• DC light (e.g. from tungsten bulb or sunlight)
• Continuous signal at 38 kHz or at any other fre-quency• Signals from fluorescent lamps with electronic bal-last (an example of the signal modulation is in the fig-ure below).

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.
