It is compliant to the latest IrDA physical layer Surface-mount package standard for fast infrared data communication, supporting High efficiency emitter IrDA speeds up to 115.2 kbit/s (SIR) and carrier base d Low profile (universal) package capable of surface-mount remote control. The transceiver module consists of a PIN soldering to side and top view orientation photodiode, an infrared emitter (IRED), and a low-power control IC to provide a total front-end solution in a single Directly interfaces with various super I/O and encoder / package. decoder devices This device covers an extended IrDA low power range of Tri-state-receiver output, floating in shut down with a close to 1 m. With an external current control resistor the weak pull-up current can be adjusted for shorter ranges. Compliant with IrDA background light specification The RXD output pulse width is independent of the optical EMI immunity in GSM bands > 300 V/m verified input pulse width and stays always at a fixed pulse width Qualified for lead (Pb)-free and Sn/Pb processing (MSL4) thus making the device optimum for standard endecs. Material categorization: for definitions of compliance TFDU4301 has a tri-state output and is floating in shut-down please see www.vishay.com/doc 99912 mode with a weak pull-up.

IRED current can be decreased by CC2 V CC2 1 adding a resistor in series between the power supply and IRED anode. A separate IRED anode unregulated power supply can be used at this pin 2 IRED cathode IRED cathode, internally connected to the driver transistor This Schmitt-Trigger input is used to transmit serial data when SD is low. An on-chip protection circuit disables the LED driver if the TXD pin is asserted for longer than 100 s. 3TXD IHigh The input threshold voltage adapts to and follows the logic voltage swing defined by the applied supply voltage Received data output, push-pull CMOS driver output capable of driving standard CMOS or TTL loads. During transmission the RXD output is active and mirrors the transmit signal. No 4RXD OLow external pull-up or pull-down resistor is required. Floating with a weak pull-up of 500 k (typ.) in shutdown mode. The voltage swing is defined by the applied supply voltage Shutdown.

IrPhy 1.3 extended the low power option to MIR and FIR and VFIR was added with IrPhy 1.4. A new version of the standard in any case obsoletes the former version. With introducing the updated versions the old versions are obsolete. Therefore the only valid IrDA standard is the actual version IrPhy 1.4 (in Oct. 2002).
