IRED anode, connected via a current limiting resistor to V
Transmitter data input. Setting this input above the threshold turns on the transmitter.
This input switches the IRED with the maximum transmit pulse width of about 100 µs.
Power supply, 2.4 V to 3.6 V. This pin provides power for the receiver and transmitter
Receiver output. Normally high, goes low for a defined pulse duration with the rising

Definitions:
In the Vishay transceiver datasheets 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 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.
