Optoisolator CTR 100% or 35%
(1/1)
Poe:
The below datasheet lists a minimum CTR of 100% at table 4.2, yet graphs 4 and 11 imply 35% MAX.

Before I contact them, just wanted to check to see if I'm missing something.
David Hess:
It looks like a mistake to me.
MagicSmoker:
Yeah, the 100% CTR at 10mA spec is definitely a typo; the figure 4 graph looks about right for a 4N25/4N35 series opto.
