Vishay TFDU5307 Data Handbook
Summary
The TFDU5307 is a high-performance, low-power Infrared Transceiver Module designed for reliable IrDA communication up to 1.152 Mbit/s. This complete front-end solution integrates the emitter, receiver, and control logic into a compact, surface-mount module. Ideal for engineers developing consumer electronics, telecommunication devices (phones), or industrial equipment that requires robust, bi-directional wireless infrared links. It guarantees long-range performance and low power consumption across standard computing voltage ranges.

Frequently Asked Questions
What speeds does the TFDU5307 support for IrDA communication?
It supports IrDA speeds up to 1.152 Mbit/s and operates using a 18102 carrier based remote control mode.
How far can this transceiver operate?
The system can operate from nose pointing up to 70 cm when supplied with two power sources.
What external components are required for setup?
Only a V bypass capacitor and a serial CCgle package resistor are the minimum external components needed.
How is module shutdown initiated?
Placing the SD pin active IHIGH for longer than 1.5 ms puts the module into shutdown mode.
