Features & Applications

The TFDU4301-TT1 is a low profile (2.5 mm) infrared transceiver module. It is compliant to the latest IrDA® physical layer standard for fast infrared data communication, supporting IrDA speeds up to 115.2 kbit/s (SIR) and carrier based remote control.

This device covers an extended IrDA low power range of close to 1 m. With an external current control resistor the current can be adjusted for shorter ranges.


  • Operates from 2.4 V to 5.5 V within specification over full temperature range from - 30 °C to + 85 °C
  • Split power supply, transmitter and receiver can be operated from two power supplies with relaxed requirements saving costs, US - patent no. 6,157,476
  • Extended IrDA low power range to about 70 cm
  • Typical remote control range 12 m
  • Low power consumption (< typ. supply current 70 μA)
  • Power shutdown mode (< 1 μA shutdown current in full temperature range, up to 85 °C)
