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. Voltage ratings are valid provided
other ratings are not violated; current ratings are valid provided the other ratings are not violated.
