Vishay Intertechnology Inc. announced that they have developed two IrDA serial infrared (SIR) transceivers that enable mobile phones and PDAs to function as universal remote controls for televisions, DVD players and recorders, and other home appliances over a range of 5.5 meters.

With the smallest available package dimensions (1.6(H)-by-6.8(L)-by-2.8(?)mm) in the industry, Vishay said, the TFBS4650 and TFBS4652 transceivers offer a 25 percent lower 75?A idle current and a 36 percent higher 12.5mW/sr transmit intensity than the HSDL3208 and HSDL3209.

The operating voltage range of the two SIR transceivers is from 2.4V to 3.6V. The TFBS4650 I/O voltage is dependent on the voltage of the external power supply. The TFBS4652 I/O voltage can be as low as 1.5V, allowing direct connection to a microcontroller's I/Os with 1.5V or lower logic. Integrated EMI protection eliminates the need for an external shield.

Both the TFBS4650 and TFBS4652 are Pb-free and capable of Pb-free processing, as well as being fully compliant with the European Union's RoHS 2002/95/EC and WEEE 2002/96/EC environmental directives. These transceivers are also fully compliant with IrDA Physical Layer and IEC60825-1 Class 1 Eye Safety specifications.
