| TEKS5400 Vishay Telefunken Silicon Photodetector with Logic Output Description TEKS5400 is a high sensitive photo Schmitt Trigger in a sideview molded plastic package with spherical lens. It is designed with an infrared filter to spectrally match to GaAs IR emitters (l = 950 nm). The photodetector is case compatible to the TSKS5400 GaAs IR emitting diode, allowing the user to assemble his own optical sensor. Features D D D D D D D D D D Very high photo sensitivity Supply voltage range 4.5 to 16 V Low current consumption (2 mA) Side view plastic package with lens Angle of half sensitivity = 30 TTL and CMOS compatible Open collector output Output signal inverted (active `low') Case compatible with TSKS5400 Ordering code: TEKS5400-ESZ (1.27 mm Pin distance) TEKS5400-EGZ (2.00 mm Pin distance) 14 355 Absolute Maximum Ratings Tamb = 25_C Parameter Supply voltage Output current Power dissipation Junction temperature Operating temperature range Storage temperature range Soldering temperature Test Conditions Symbol VS1 IO PV Tj Tamb Tstg Tsd Value 18 20 100 100 -25 to +85 -40 to +100 260 Unit V mA mW C C C C t x 5 s, 2 mm from body Handling Precautions Connect a capacitor C of 100 nF between VS1 and ground !

A8, 20-Jan-00 TEKS5400 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.
