Vishay Semiconductors
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.
V
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.
- allows a low-voltage controller to connect
LOGIC
The Shut Down (SD) feature cuts current consumption to less than 10 nA.
