With the low going edge of Txd a single pulse is generated at Rxd. The SD is indendet to activate the shutdown function after a delay of 1 ms. Therefore the full sequence should be run with that 1 ms time limitation, see drawing. tSD: > 5 ms for "real" shutdown > 1 ms SD tTxd: > 0.5 ms to 2 ms Txd tdelTxd: 1 ms tdelRxd: 10 ns tRxd = 400 ns Rxd Figure 6. The transmitter current is programmable and can be switched by setting the mode input (Pin 7) Mode switching affects only pulse current. Mode switch (Pin 7) set to "High": Output driver acts as switch, the current is controlled by an external resistor but limited by an internal overload protection. Mode switch set to "Low": Internal current control is activated and controls the output intensity to be compliant with the low power Telecom standart. Table 1.

In a more noisy ambient it is recommended to add a combination of a resistor and capacitor (R1, C1, C2) for noise suppression as shown in the figure below. A combination of a electrolytic for the low frequency range and a ceramic capacitor for suppressing the high frequency disturbance will be most effective. The inputs TXD and SD are high impedance CMOS inputs. Therefore, the lines from the I/O to those inputs should be carefully designed not to pick up ambient noise. If long lines are used, loads at the Txd input of the TFDx5x06 and at the Rxd input of the controller (!) are recommended. At the IRED Anode voltage supply line an additional capacitor might be necessary when inductive wiring is used. However, a low impedance layout is the better and more cost efficient solution. For adjusting the intensity depending on the application, see the diagrams. 500 5.25V 400 Intensity (mW/sr) 5.0V 300 200 100 0 0 15186 max. intensity in emission cone "15 min. Rdson, min.

In a UART related application after that time (typically 50 s) the receiver buffer of the UART must be cleared. Therefore, the transceiver has to wait at least the specified latency after receiving the last bit before starting the transmission to be sure that the corresponding receiver is in a defined state. Figure 7. Recommended Application Circuit Shut Down To shut down the TFDx5x06 into a standby mode the SD pin has to be set active. After a delay of < 1 ms it will switch to the standby mode. www.vishay.de * FaxBack +1-408-970-5600 10 (13) Document Number 82533 Rev. A1.0a, 01-Dec-99 TFDU5106 Vishay Telefunken Table 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.
