| VISHAY TFBS6614 Vishay Semiconductors Low Profile 4 Mbit/s (FIR) Infrared Transceiver Module with independent Logic Supply Voltage Description The Vishay TFBS6614 is the lowest profile (2.7 mm) 4 Mbit/s Infrared Data Transceiver module available. A photo PIN diode, an infrared emitter (IRED) and a low-power CMOS control IC are integrated in a single package that provides a total front-end solution. VLOGIC - allows a low-voltage controller to connect directly to TxD, RxD and SD/Mode logic signals of the transceiver hence eliminating the need for costly signal level converter and reducing power consumption. The TxD-echo function is enabled for internal selftest. During transmission the TxD signals are echoed at RxD output to perform the internal self-test. The Shut Down (SD) feature cuts current consumption to less than 10 nA. 18088 Features * Smallest FIR Transceiver available: H 2.7 mm x D 3.33 mm x L 7.98 mm * 1.0 m Link distance * Battery & Power Management Features: > Receive - 2 mA Typical > Shutdown - 10 nA Typical > Independent LED Anode Power Supply > Wide Voltage Range 2.7 V - 5.5 V > Power Up Latency < 100 s > High VCC Noise Rejection > 100 m VPP * The TxD-Echo function is enabled * VLOGIC (1.5 V - 5.5 V) - Independent Digital supply voltage * Shutdown Tri-States Receiver Output and Disables TxD allowing Bus Interfacing * High Immunity to Fluorescent Light Noise and AC Field.

Set SD/ Mode input to logic "High". 2. Set TxD input to logic "High". Wait ts 200 ns. 3. Set SD/ Mode to logic "Low" (the negative edge latches state of TxD, which determines data rate setting). 4. After waiting th 200 ns TxD can be set to logic "Low". The hold time of TxD is limited by the maximum allowed pulse width. TxD is now enabled as normal TxD input for the high bandwidth mode.

A1, 30-Apr-03 VISHAY 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. TFBS6614 Vishay Semiconductors 2. Regularly and continuously improve the performance of our products, processes, distribution and operatingsystems 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.
