Operating Conditions
Absolute Maximum Conditions
Stresses beyond those listed in Table 2-2 may cause permanent damage to the device. Exposure to Absolute Maximum
rated conditions for extended periods may affect device reliability. Devices should not be operated outside the
recommended operating conditions in Table 2-3.

Notes:
1. The AC transient V_CCA limit is for radiation-induced transients less than 10 µs duration and not intended for repetitive use. Core
voltage spikes from a single event transient will not negatively affect the reliability of the device if, for this non-repetitive event, the
transient does not exceed 1.8 V at any time and the total time that the transient exceeds 1.575 V does not exceed 10 µs in
duration.
2. V_CCDA must be greater than or equal to the highest V_CCI voltage

1. Ambient temperature (T_A) is used for commercial and industrial grades; case temperature (T_C) is used for military grades.
2. Please see "V_CCDA Supply Voltage" on page 2-11 more detail.
3. T_{j (max)} = 125ºC.
Overshoot/Undershoot Limits
For AC signals, the input signal may undershoot during
transitions to –1.0 V for no longer than 10% of the
period or 11 ns (whichever is smaller). Current during the
transition must not exceed 95 mA.
For AC signals, the input signal may overshoot during
transitions to V_CCI + 1.0 V for no longer than 10% of the
period or 11 ns (whichever is smaller). Current during the
transition must not exceed 95 mA.
Note: The above specification does not apply to the PCI
standard. The RTAX-S/SL PCI I/Os are compliant to the PCI
standard including the PCI overshoot/undershoot
specifications.
