11. Limiting values

[1]

The performance capability of a high-performance integrated circuit in conjunction with its thermal

environment can create junction temperatures which are detrimental to reliability. The maximum junction

temperature of this integrated circuit should not exceed 125

°C.

12. Static characteristics

Table 15.

Limiting values

In accordance with the Absolute Maximum Rating System (IEC 60134).

Voltages are referenced to VSS (ground = 0 V).[1]
