Driving a 5V output from GPIOs

Other Parts Discussed in Thread: TMS320F2808

Hello, I am using a tms320f2808 Control Card, and it is mounted on a docking station, I was wondering is there a way I can drive out a 5V output signal instead of a 3.3V

Regards,

The TMS320F2808 is only capable of driving 3.3V output. You would need some level translation to drive a 5V output.

Hint: If you can find a level translator on TI's site, you can probably order a free sample or two, maybe something like http://www.ti.com/product/sn74lvc2t45?

Hi Forat!

I would recommed you this material 5556.TI_3.3V DSP for Digital Motor Control_spra550.pdf. There you can find methods of interfacing different voltage levels for any cases.
