1. TJ = 100°C
2. Applicable to 3.3 V LVCMOS Wide Range. IOSL/IOSH dependent on the I/O buffer drive strength selected
for wide range applications. All LVCMOS 3.3 V software macros support LVCMOS 3.3 V wide range as
specified in the JESD-8B specification.
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, 12 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.

Note:
*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.
Microsemi recommends signal integrity evaluation/characterization of the system to ensure that
there is no excessive noise coupling into input signals.
