I need a unidirectional way to connect a LM1881 sync separator operating at 5V to a dsPIC operating at 3.3V, so I need to translate the 5V signal down to 3.3V.
I could use a voltage divider but I was thinking, could I just take advantage of the internal diodes that the dsPIC has to clamp the 5V to 3.3V through current limiting resistors? I am trying to build this on a small stripboard so size is a driving factor.
I don't want to blow up my dsPIC because they are £4 each and I only have two of them.
