Levelshifting 3->5V. Can I add a DC bias of 0.5v or so to the 5v input line to bring up the 3v signals?
Assuming it doesn't just line up correctly, eg: If my Vih is 3.6v on the 5v side, and my Voh is 3.3v on the 3v side.
By DC bias I mean connecting up a voltage divider giving 0.5v to the line connecting the 3v->5v.
I'm guessing this isn't done as it would drain power when the 3v line goes low, but if the divider is high enough resistance, that could be minimal?
