'Simplest way to connect 5V with 3V logic'
In my current project, I need to connect a MPU powered by 3V to a DSP
powered by 5V. The probelm lies in connecting the bi-directional DATA
line in two different logic systems. In this case, I have selected two
open-drain ports to act as data pins, but I haven't yet found the
simplest way to convert the levels properly.
Would you be so kind to show me your solutions?
Thanks in advance!

So does TI and Toshiba. You can tie the voltage for the 'other' bus to what
ever rail you want. I know the TI parts does not require power sequencing,
but dunno about the cypress part.
