Oh no! Active low signal? just kidding.
Yes, that's what the 2C and the new board have. So it's just POIFECT for the IGBT boards. ya!
The cool thing is, just adding a resistor from pin 2 to pin 3 of the HCPL-4506 footprint gives you the pull up you would need, since the dang chip would be gone in the igbt application! ya! Now tell me I wasn't sneaky... go ahead. tell me. hahaha
