The TFDU6301 transceiver is an infrared transceiver module compliant to the latest IrDA physical layer low-power standard for fast infrared data communication, supporting IrDA speeds up to 4 Mbit/s (FIR), HP-SIR®, Sharp ASK^® and carrier based remote control modes up to 2 MHz. Integrated within the transceiver module is a photo PIN diode, an infrared emitter (IRED), and a low-power control IC to provide a total front-end solution in a single package.

This new Vishay FIR transceiver is built in a new smaller 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 VCC bypass capacitor is the only external component required implementing a complete solution. TFDU6301 has a tri-state output and is floating in shutdown mode with a weak pull-up.

An otherwise identical transceiver with supply voltage related logic levels is available as TFDU6301.
