Is a level shifter the right thing, or a hex buffer? Which chip could achieve that?
Reason for my question is that until now I worked a lot with L293D motor controller, which allows up to 36V as motor voltage. Therefore I could use 4 fully loaded (3.7V) LiPos with 4x4.2V=16.8V as motor voltage easily.
With Arduebot I use Arduino Due which is 3.3V microcontroller, which cannot control L293D 4.5V-7V logic level without level shifters.
This is the reason why I work with TB6612FNG motor driver  since some time [one did explode recently ;-)]. It has logic voltage 2.7-5.5V which is fine for Arduino Due, but maximum motor voltage of 15V. So I need to reduce 16.8V to
