The definition and values of input/output AC characteristics are given in Figure 37 and Table 50 , respectively.

Unless otherwise specified, the parameters given in Table 50 are derived from tests performed under the ambient temperature and V DD supply voltage conditions summarized in Table 14 .

Stresses above the absolute maximum ratings listed in Table 11: Voltage characteristics , Table 12: Current characteristics , and Table 13: Thermal characteristics may cause permanent damage to the device. These are stress ratings only and functional operation of the device at these conditions is not implied. Exposure to maximum rating conditions for extended periods may affect device reliability. Device mission profile (application conditions) is compliant with JEDEC JESD47 Qualification Standard, extended mission profiles are available on demand.

Table 12. Current characteristics

1. Positive injection is not possible on these I/Os. A negative injection is induced by V IN <VSS . I INJ(PIN) must never be exceeded. Refer to Table 11 for the values of the maximum allowed input voltage.
2. A positive injection is induced by V IN >VDD while a negative injection is induced by V IN <VSS . I INJ(PIN) must never be exceeded. Refer to Table 11 for the values of the maximum allowed input voltage.
3. When several inputs are submitted to a current injection, the maximum Σ I INJ(PIN) is the absolute sum of the positive and negative injected currents (instantaneous values).

Table 13. Thermal characteristics

The maximum chip-junction temperature, T J max, in degrees Celsius, may be calculated using the following equation:

T J max = T A max + (P D max x Θ JA )

In order to meet environmental requirements, ST offers these devices in different grades of ECOPACK packages, depending on their level of environmental compliance. ECOPACK specifications, grade definitions and product status are available at: www.st.com . ECOPACK is an ST trademark.
