| TSOP28..PM Vishay Telefunken Photo Modules for PCM Remote Control Systems Available types for different carrier frequencies Type TSOP2830PM TSOP2836PM TSOP2838PM TSOP2856PM fo 30 kHz 36 kHz 38 kHz 56 kHz Type TSOP2833PM TSOP2837PM TSOP2840PM fo 33 kHz 36.7 kHz 40 kHz Description The TSOP28..PM - series are miniaturized receivers for infrared remote control systems. PIN diode and preamplifier are assembled on lead frame, the epoxy package is designed as IR filter. The demodulated output signal can directly be decoded by a microprocessor. The main benefit is the reliable function even in disturbed ambient and the protection against uncontrolled output pulses. 1 2 3 14320 Features D D D D D Photo detector and preamplifier in one package Internal filter for PCM frequency TTL and CMOS compatibility Output active low Improved shielding against electrical field disturbance Special Features D Small size package D Enhanced immunity against all kinds of disturbance light D No occurrence of disturbance pulses at the output D Short settling time after power on (<200ms) D Suitable burst length 6 cycles/burst Block Diagram 2 Input Control Circuit VS 30 kW 1 OUT PIN AGC Band Pass Demodulator 3 GND 14318 Rev.

A1, 18-Nov-98 5 (6) TSOP28..PM Vishay Telefunken 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-Telefunken products for any unintended or unauthorized application, the buyer shall indemnify Vishay-Telefunken 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.
