One project I'm going to use BAT54S to protect the digital inputs.
Question on the pull-up voltage. Any reason to use 3.3V, 5V or 12V?
I have 3.3V currently on the pull-up, and if I put 5V (or 12V) on the input, the output to Teensy is 3.587V (I'm assuming the chip can handle 3.3V +/- 0.3V)
The examples I have come across are for Arduino that handles 5volts, and they have 12v for pull-up.
