I already damaged 2 TIL311 :-(

I wonder what happened but I suspect my new fancy digital lab power supply. Turning it off while the circuit is still connected could send spikes that damage the pins...

So I have to implement the power supply ASAP or I'll burn my stock of TIL311 quickly :-/

Lesson learned : TIL311 are quite fragile...
