8. Limiting values
[1] Equivalent to discharging a 100 pF capacitor through a 1.5 k series resistor.
9. Thermal characteristics
10. Characteristics
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 and current
ratings are valid provided the other ratings are not violated.
