Some means of managing the transition between voltages is required, so we’re going to take a look at the world of level shifters, the circuits we use when interfacing these different voltage ...

Often multiple voltage domains are being created in order to cater the need of low power requirements and to communicate between these two domains level shifters are being used. However, these ...

So usually we’d say “add a level shifter to convert 3.3V to 5V” and ... since it’s operating at a lower voltage, but that’s a trade off [todbot] made to simplify this design.
