Timing parameters are equivalent to TSOP1238, see that datasheet.
Using an external current limiting resistor is allowed and recommended to reduce IRED intensity and operating current when current
The RC-RXD output is an open collector output, therefore a load resistor is mandatory.
Note: Due to this wavelength restriction compared to the IrDA spec of 850 nm to 900 nm the transmitter is able to operate as source for
