According to datasheet K10P144M100SF2V2 GPIO only have clamp diode to VSS. I need EOS protection up to +24V.
I can experiment and find what works but I will like to understand GPIO characteristics.
Can I use a series 10K resistor for protection?
Will it cause latchup because 24V > Max 5~5.5V even though it can't drive latch up current of 100ma?
What will be the voltage at pin?
What is the reverse break down voltage of clamp diode?
Will I I definitely need another clamp diode to VDD as well ? Why?
