RoHS 10 Compliant

The TFDU4101 transceiver is an infrared transceiver modulecompliant to the latest IrDA® physical layer standard for fastinfrared data communication, supporting IrDA speeds up to115.2 kbit/s (SIR), and carrier based remote control modes.Integrated within the transceiver module are a photo pindiode, an infrared emitter (IRED), and a low-power control ICto provide a total front-end solution in a single package. Thisdevice covers the full IrDA range of more than 1 m using theinternal intensity control. With one external current controlresistor the current can be adjusted for shorter rangessaving operating current operating in IrDA low power mode.This Vishay SIR transceiver is using the lead frametechnology.

The receiver output pulse duration is independent of theoptical input pulse duration and recovers always a fixedpulse duration optimum for compatibility to standardEndecs and interfaces. TFDU4101 has a tristate output andis floating in shutdown mode with a weak pull-up.

Key Features

  • 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
  • Low power consumption (< 0.12 mA supply current in receive mode, no signal)
  • Power shutdown mode (< 4 μA shutdown current in full temperature range, up to 85 °C, < 10 nA at 25 °C)
  • Surface mount package (L x W x H in mm): 9.7 × 4.7 × 4
  • High efficiency emitter
  • Low profile (universal) package capable of surface mount soldering to side and top view orientation
  • Directly Interfaces with various super I/O and controller devices as e. g. TOIM4232
  • Tri-state-receiver output, floating in shut down with a weak pull-up
  • Qualified for lead (Pb)-free and Sn/Pb processing (MSL4)
