CNY70 product information

The CNY70 is a reflective sensor that includes an infrared. I couldn’t find anything about the ON state resistance of the datasyeet, which could make things much easier for me. For most practical purposes this device is not going to do a good job of driving an LED directly. I couldn’t find anything about the ON state resistance of the transistor, which espall make things much easier for me Could you please explain what calculations should I do, or which figures should I check in the data sheet in order to calculate the X resistance value for safe operation.

It’s more like a current source until Vce drops to below a volt or so.
