Optoisolator CTR questions

When the optoisolator datasheet gives min,max and typ values for the
CTR,how do we decide which value is consider?

Also,does the CTR depend on the Vcc?If yes,how is the relation
determined?

And what is meant by Normalised CTR,the parameter that the datasheet
show the graphs with respect to?

Thanks.

All of them. Your circuit has to operate with all of
them I assume.

If you are designing a circuit for production then you must design a circuit
that will work with any CTR between the min and max value
