Dear TI,
I would like to make a universal slow, Digital In on my PCB for 3V to 30V. Is it sufficient to just use a big input resistor (47k) and let the internal clamping diodes in the tm4c handle the high voltage?
- Are the clamping diodes capable to handle the 30V?
- Are they capable to handle 700uA?
thanks in advance.
Chris
