Hello all
I want to jump over to Teensy 4.1's, as 3.2's appear to be impossible to find at the moment.
So, I want to incorporate level shifting in my board design and I see that Sparkfun and other people use a small 3 pin device. Any idea what that part is? BS170?
I understand that I can use something like a 74HCTxx. I basically want to make all the pins 5v tolerant.
But, I assume the analogue pins still have to stay 3.3v input? Would level shifting these analogue pins make them read 0-5v?
Also, if I make the 3.3v pins 5v tolerant with a level shifter, will it still operate correctly at 3.3v high?
I could voltage divide, but I would like to do the job properly
Thanks
