Revision 13
The length of time an I/O can withstand IOSH/IOSL events depends on the junction temperature. The
reliability data below is based on a 3.3 V, 36 mA I/O setting, which is the worst case for this type of
analysis.
For example, at 100°C, the short current condition would have to be sustained for more than six months
to cause a reliability concern. The I/O design does not contain any short circuit protection, but such
protection would only be needed in extremely prolonged stress conditions.
