TFDS4400
Vishay Semiconductors
wwwS.DaItRaSheTet4rUa.conmsceiver Module (115.2 kbit/s)
2.7 V to 5.5 V
Description
The TFDS4400 is a low–power infrared transceiver
module compliant to the IrDA physical layer standard
for infrared data communication, supporting IrDA
speeds up to 115.2 kbit/s (SIR), HP-SIR, and carrier
based remote control modes up to 100 kHz. Integrated
within the transceiver module are a photo PIN diode,
infrared emitter (IRED), and a low–power control IC to
provide a total front–end solution in a single package.
Vishay Semiconductors TFDS4400 transceiver
represents a novel package option enabling a
minimized package height over the PCB of only
1.8 mm and nevertheless offering a full 1m IrDA 1.2
transmission range. The transceiver is capable of
directly interfacing with a wide variety of I/O chips
which perform the modulation/demodulation function,
including National Semiconductor’s PC87338,
PC87108 and PC87109, SMC’s FDC37C669,
FDC37N769 and CAM35C44, and Hitachi’s SH3. At a
minimum, a current– limiting resistor in series with the
infrared emitter and a VCC bypass capacitor are the
only external components required to implement a
complete solution.

Label
Standard bar code labels for finished goods
The standard bar code labels are product labels and
used for identification of goods.The finished goods are
packed in final packing area. The standard packing
units are labeled with standard bar code labels before
transported as finished goods to warehouses. The
labels are on each packing unit and contain Vishay
Semiconductor GmbH specific data.
