A product selector guide for Vishay's infrared data communication transceivers, detailing specifications and applications for models TFDU4101 through TFBS4652.
This document serves as a selector guide for Vishay InterTechnology's IRDC (Infrared Data Communication) optoelectronics. It highlights the strategic importance of maintaining availability for these transceivers, which enable short-distance wireless communication at speeds up to 115 kbit/s.
The guide provides technical specifications and application areas for five specific models: TFDU4101, TFDU4301, TFBS4711, TFBS4650, and TFBS4652. Key features include I/O voltage flexibility ranging from 1.5 V to 1.8 V, allowing direct connection to microcontrollers without level converters.
| Data Rate | 115 kbit/s |
|---|---|
| I/O Voltage Range (Fixed) | 1.8 V |
| I/O Voltage Range (Flexible) | 1.5 V to 1.8 V |
| Operating Voltage (TFDU4101, TFDU4301) | 2.4 to 5.5 V |
| Operating Voltage (TFBS4650, TFBS4652) | 2.4 to 3.6 V |
The transceivers are designed for use in metering, medical, vending, consumer, and access control applications.
Many models feature I/O voltage levels equal to 1.8 V, which eliminates the need for voltage level converters.
