IGLOO nano DC and Switching Characteristics
2- 24
Advance v0.2
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, 8 mA I/O setting, which is the worst case for this type of
analysis.
For example, at 110°C, the short current condition would have to be sustained for more than three
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.

* The maximum input rise/fall time is related to the noise induced into the input buffer trace. If the
noise is low, then the rise time and fall time of input buffers can be increased beyond the
maximum value. The longer the rise/fall times, the more susceptible the input signal is to the
board noise. Actel recommends signal integrity evaluation/characterization of the system to
ensure that there is no excessive noise coupling into input signals.
