I stumbled across this ckt - http://husstechlabs.com/support/tutorials/bi-directional-level-shifter/
It says it's a bidirectional level shifter (3.3 to 5v or 5 to 3.3v)
I can't figure out how it would work when level shifting 5v to 3.3v
When the drain is 5v, the source should be 3.3V
When the drain is 0v, the source should be 0v (how can the drain be 0v)?
