Lowest Profile 4 Mbits/s (FIR) Infrared Transceiver Module
Description The Vishay TFBS6614 is the lowest profile (2.7 mm) 4 Mbit/s Infrared Data Transceiver module available. A PIN photodiode, 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 Tx D, Rx D and SD/Mode logic signals of the transceiver hence eliminating the need for costly sig- nal level converter and reducing power consumption. The Tx D-echo function is enabled for internal self- test. During transmission the Tx D signals are echoed at Rx D output to perform the internal self-test.
The Shut Down (SD) feature cuts current consump- Applications tion to less than 10 n A.

Frequently Asked Questions
How is the module's internal function tested?
The TFBS6614 performs an internal self-test by echoing the TxD signals at the RxD output during transmission.
What is the shutdown current consumption of the unit?
When using the shut down feature, the current consumption drops to less than 10 nA typical.
How can I switch between high and low data bandwidth modes?
Mode switching is controlled by setting the SD/Mode input signal to specific logic levels according to a sequence of steps.
Is this product compliant regarding restricted chemicals?
Yes, Vishay certifies that the semiconductor modules are not manufactured with ozone depleting substances (ODSs).
