Absolute Maximum Ratings

Reference point pin, GND unless otherwise noted.

Typical values are for DESIGN AID ONLY, not guaranteed nor subject to production testing.

Eye safety information

Reference point pin: GND unless otherwise noted.

Definitions:

In the Vishay transceiver data sheets the following nomenclature is used for defining the IrDA operating modes:

SIR: 2.4 kbit/s to 115.2 kbit/s, equivalent to the basic serial infrared standard with the physical layer version IrPhy: 1.0

MIR: 576 kbit/s to 1152 kbit/s

FIR: 4 Mbit/s

VFIR: 16 Mbit/s

MIR and FIR were implemented with the physical layer standard IrPhy 1.1, followed by IrPhy 1.2, adding the SIR low power standard.

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.

Note: We apologize to use sometimes in our documentation the abbreviation LED and the word light emitting diode instead of infrared

emitting diode (IRED) for IR-emitters. That is by definition wrong; we are here following just a bad trend.

Typical values are for design aid only, not guaranteed nor subject to production testing and may vary with time.
