Bi-directional Level Shifter - 1 MOSFET

For data lines which are pulled high by resistors, simply place a single enhancement-mode n-channel MOSFET as shown to perform bi-directional level shifting.

You will notice the inputs are or-ed together, so that if either is pulled low, both are forced low.

Cool. In real life transistor should be small signal mosfet like bs138.
