The TFDU5307 is an infrared transceiver module compliant to the latest IrDA physical layer standard, supporting IrDA speeds up to 1.152 Mbit/s (MIR) and carrier based remote control modes up to 2 MHz. Integrated within the transceiver module are a PIN photodiode, an infrared emitter (IRED), and a low-power control IC to provide a total front-end solution in a single package.

This Vishay MIR transceiver is built in a low profile package using the experiences of the lead frame babyface technology. The transceivers are capable of

directly interfacing with a wide variety of I/O devices, which perform the modulation/ demodulation function. At a minimum, a V_CC bypass capacitor and a serial resistor for current control are the only external components required implementing a complete solution. TFDU5307 has a tri-state output and is floating in shutdown mode with a weak pull-up.
