I/O Reliability
For typical continuous drive applications, I/O pins configured between 2 mA and 12 mA and operating
at -40 to 85°C, meet the standard 10-year lifetime reliability. If a continuous current sink of 18 mA
is required, then operation is limited to 0 to 75°C in order to meet the standard 10-year reliability.
At 105°C, I/O configured for continuous drive meet the standard 2.5 year lifetime reliability.
In typical switching applications (40% switch rate) operating at -40 to 85°C, all I/O configurations
except 2 mA meet the standard 10-year lifetime reliability with 50-pF loading. By limiting the capacitive
loading to 20 pF for an I/O configured to 2 mA, the 10-year lifetime reliability can be met at -40 to
85°C.
In typical switching applications (40% switch rate) operating at 105°C, all I/O configurations except
2 mA meet the standard 2.5-year lifetime reliability. By reducing the capacitive loading to 20 pF with
a typical switching rate at 105°C, a 2-mA I/O configuration meets a 2.5 year lifetime reliability.
