Hi,
anyone knows who made the KT3172 optocoupler, and may be has a datasheet? It seems I can't find it.
Thanks,

Like a lot of numbers..
from what I can see it is a 4 pin device ? and if so, the pins 1 and 2 are the input LED or LED's, if could be an AC type? to test that, you can use the diode test and it should test the same both ways as a LED diode.
The output looks like a NPN transistor. Collector is on 4 and emitter on 3.
But, maybe I have it incorrect..

FWIW, the following discussion suggests that KT3172 crosses to HP part
