Latch-up performance

Question asked by Claes-Henry Aronsson on Nov 25, 2015

To avoid latch-up or malfunctions the I/O pins should not be externally driven while the I/O supply is OFF.

At what current do you consider an I/O pin to be driven?

 

Will an external 100k resistor, pulled up to external 3.3V, drive the I/O pin?

 

Best Regards
