8. Limiting values
[1] The input and output negative voltage ratings may be exceeded if the input and output clamp current ratings
are observed.
[2] The performance capability of a high-performance integrated circuit in conjunction with its thermal
environment can create junction temperatures which are detrimental to reliability.
9. Recommended operating conditions
Table 5: Limiting values
In accordance with the Absolute Maximum Rating System (IEC 60134). Voltages are referenced to
GND (ground = 0 V).
