TFDH6131/TFDH6541
Vishay Telefunken
Fast Infrared Transceiver Module Family
(FIR, 4 Mbit/s) for 2.6 V to 5.5 V Operation
Description
The TFDH6131 and TFDH6541 transceivers are is based on the standard package with the leads single
package modification inside the 6000E – family of in line (SIL), the other based on the BabyFace
low–power infrared transceiver modules compliant to package, leads dual in line. The transceivers are
the IrDA physical layer standard for fast infrared data capable of directly interfacing with a wide variety of I/O
communication, supporting IrDA speeds up to 4 Mbit/s devices which perform the modulation/ demodulation
(FIR), HP-SIR, Sharp ASK and carrier based remote function,
including
National
Semiconductor’s
control modes up to 2 MHz. Integrated within the PC87338, PC87108 and PC87109, SMC’s
transceiver modulesareaphotoPINdiode, aninfrared FDC37C669, FDC37N769 and CAM35C44, and
emitter (IRED), and a low–power CMOS control IC to Hitachi’s SH3. At a minimum, a current–limiting
