8. Limiting values

Table 3. Limiting values

In accordance with the Absolute Maximum Rating System (IEC 60134). All voltages are measured with respect to ground

(pin 2); positive currents flow into the chip. The voltage ratings are valid provided other ratings are not violated; current ratings

are valid provided the other ratings are not violated.
